# ListAttempts

> List every attempt made for one delivery, oldest first. A delivery is
 attempted at most ten times, so the result is small and is not paginated.

      DeliveriesService reports what was sent to your notification integrations
      —
       webhooks, PagerDuty, Opsgenie — and what came back.

       It answers the three questions an integration owner has. "Did this event
       reach my endpoint": list the deliveries for an event id and read the outcome
       of each. "Why did my endpoint reject it": read the attempts, which carry the
       request as it was sent and the response as it came back. "Why did I get
       nothing at all": every delivery that sent nothing records a reason, so a
       silent integration can be explained rather than guessed at.

       Deliveries are kept for 90 days. Credential-bearing header values are never
       returned, on either side of an attempt — see `Header`.
  - name: synq.savedviews.v1.SavedViewsService
    description: >-
      SavedViewsService manages saved views — named, reusable selections over
      your
       entities (and other surfaces) with display configuration, sharing and
       per-user pinning.

       A saved view is owned by the user who created it. It can be kept private,
       shared with the whole workspace, or granted to specific users. Reads return,
       for the calling user, how each view relates to them (mine / shared / granted)
       and what they are allowed to do with it. Workspace administrators can manage
       any view in the workspace.

  - name: synq.integrations.v1.IntegrationsService
    description: |-
      IntegrationsService manages connections from Coalesce Quality to your data
       systems (warehouses, databases, and transformation tools).

       Concurrency: every integration carries an opaque `etag`. Read it from
       `GetIntegration` / `ListIntegrations`, then pass it back on
       `UpdateIntegration` / `DeleteIntegration` to ensure you modify the version you
       last saw. A stale etag is rejected with ABORTED (HTTP 409). Omit
       the etag for last-write-wins.

       Quota: each workspace has a limit on the number of integrations. Creating
       beyond the limit is rejected with RESOURCE_EXHAUSTED.

       Secrets: credential fields (passwords, tokens, keys) are write-only. They are
       masked (returned empty) on every read. On update, omit a secret to keep it,
       send a new value to rotate it, or send an explicit empty string to clear it
       (where the field is `optional`).
  - name: synq.queries.v1.NLQueryService
    description: >-
      NLQueryService generates structured Query protos from natural language
      descriptions using an LLM.
  - name: synq.queries.v1.QueriesService
    description: |-
      QueriesService compiles and evaluates ResolverQL — the compact text query
       language used across Coalesce Quality to select entities — over the public
       API.

       ResolverQL is a string DSL (for example `with_type("TABLE")` or
       `in_folder(...)`); a structured `synq.queries.v1.Query` is its parsed,
       machine-readable form. This service is the bridge between the two and the
       read-only execution surface for both:
         - `TranslateResolverQl` compiles a ResolverQL expression into a structured
           `Query` without evaluating it — inspect it, validate it, or reuse it as a
           filter on another API (entity listing, folder browsing, ...).
         - `ResolveQuery` compiles a ResolverQL expression (or takes an
           already-structured `Query`), evaluates it against the catalog, and
           returns the matched entity ids. This is the general author -> resolve
           loop.

    description: >-
      EntityExecutionsService provides read-only access to entity execution
      history.
       This service allows customers to retrieve information about all executions that happened on their entities,
       including execution status, timing, and messages.

       Use cases:
       - Retrieve execution history for specific entities
       - Filter executions by time range, status, or execution type
       - Get aggregated summaries of execution activity
       - Track execution trends and patterns
  - name: synq.entities.executions.v1.EntityExecutionsService
    description: 'Deprecated: Use [synq.entities.custom.v1.EntityExecutionsService] instead'
  - name: synq.entities.lineage.v1.LineageService
    description: |-
      LineageService allows you to fetch:
       * Entity level lineage from a starting point of one or more entities.
       * Column Level lineage from a starting point of multiple columns of a single entity.
  - name: synq.entities.checks.v1.ChecksCategoriesService
    description: |-
      ChecksCategoriesService lets workspace admins set explicit category
       overrides on individual checks. An explicit category is the
       authoritative category for a check — it takes precedence over the
       categories computed by the workspace's categorisation rules.

       It is a public API so customers can manage check categories
       programmatically; the same service is also mounted on the internal
       API. The workspace and the acting identity are always taken from the
       request context, never from the payload.
  - name: synq.entities.constraints.v1.TableConstraintsService
    description: >-
      TableConstraintsService provides access to table constraint and index
      information.
  - name: synq.entities.sql_insights.v1.SqlInsightsService
    description: >-
      SqlInsightsService exposes analytical information about the SQL used
      across a
       workspace's entities. It answers questions such as "which SQL constructs are
       used in my warehouse, and how often" and "what SQL constructs does this
       specific entity use", without requiring the caller to re-parse any SQL.
  - name: synq.entities.status.v1.EntityIncidentsService

  - name: synq.entities.orchestration.v1.OrchestrationService
    description: >-
      OrchestrationService provides information about orchestration
      relationships between entities.
       This includes relationships between Airflow tasks and transformation models (dbt, SQLMesh),
       as well as task-to-task dependencies.
  - name: synq.entities.annotations.v1.AnnotationsService
    description: >-
      AnnotationsService provides operations for managing and querying entity
      annotations.
       Annotations are key-value pairs that can be attached to entities for categorization and filtering.
  - name: synq.entities.custom.v1.RelationshipsService
    description: >-
      RelationshipsService allow management of relationships between entities.
      Relationships can
       be created, updated, and deleted between 2 custom entities, or between a custom entity and Coalesce Quality native entity.enum
       There is no option to create relationships between 2 Coalesce Quality native entities (dbt model, BI dashboard, etc.).
  - name: synq.entities.custom.v1.EntityExecutionsService
  - name: synq.entities.custom.v1.FeaturesService
  - name: synq.entities.custom.v1.EntitiesService
    description: >-
      custom.EntitiesService is a service for managing custom entities. Entities
      can represent
       various data platform concepts such as services, consumers, applications or data pipelines
       that are not natively available in Coalesce Quality.

       Entities are identified by a unique identifier and can be created, updated, read and deleted.
  - name: synq.entities.custom.v1.GroupsService
    description: >-
      It eliminates the need to keep state on client side to remember which
      assets were already created
       and which should be deleted. The server will keep track of the current state of the group and client
       can always send the intended new state. The server will calculate the diff and entities that are
       no longer present in the group will be removed.

       Example:
       1. group has entities A, B, C at time t1
       2. client sends group with entities B, C, D at time t2
       3. server will remove entity A from the system and update the current state of the group to B, C, D

       The service is designed to be idempotent and can be called multiple times with the same state without
       causing any side effects.
  - name: synq.entities.custom.v1.TypesService
    description: TypesService is a service for managing custom entity types.
  - name: synq.entities.custom.v1.ChecksRelationshipsService
  - name: synq.entities.folders.v1.FoldersService
    description: >-
      FoldersService discovers and browses the folder / containment hierarchy of
      the
       catalog: the roots data hangs from, the sub-folders under any folder, the
       folders a given entity lives in, and the entities contained in a folder.

       It is a read / navigation surface, not folder management — there are no
       create, move, or delete operations.

       Addressing: every folder has an opaque `folder_entity_id` (round-trip it
       verbatim) and a structured `FolderRef{root_entity_id, folders[]}` (the
       human-friendly form). Entities — both folder members and the ids you pass to
       `GetFolderOf` — are named by their opaque entity id, the same id used across
       the rest of the entities API.

       Depth footgun: membership is SHALLOW by default. `Browse` returns only the
       direct children of a folder, and `ListMembers` returns only the entities
       placed directly in the folder. Set `deep = true` (or raise `Browse.depth`) to
       recurse into sub-folders.
  - name: synq.entities.schemas.v1.SchemaMismatchesService
    description: >-
      SchemaMismatchesService provides access to schema drift information
      between
       data platform tables and their definitions (e.g., dbt models).
  - name: synq.entities.schemas.v1.SchemasService
    description: EntitiesService is a service for retriving any entity.
  - name: synq.entities.resolve.v1.IdentifierResolveService
    description: >-
      IdentifierResolveService resolves identifiers to their Coalesce Quality
      paths and identities.
  - name: synq.entities.changes.v1.ChangesService
    description: >-
      ChangesService provides functionality to track and retrieve all types of
      changes to data entities.

       This unified service returns ALL change types for an entity:
       - Git commits: Changes to code files (dbt models, SQL files) tracked in version control
       - Schema changes: Database schema modifications (columns added/removed/changed)
       - SQL definition changes: View/materialized view definition updates detected by Coalesce Quality

       Changes are returned with structured metadata including:
       - For git commits: structured statistics (directories, file types, top changes)
       - For schema changes: detailed column-level diffs
       - For SQL changes: before/after SQL definitions

       Use cases:
       - "What changed in the last week for table X?" → Returns git commits, schema changes, SQL changes
       - "Show me all commits affecting this dbt model" → Returns git commits with lineage context
       - "What schema changes happened to this table?" → Returns schema changes detected by Coalesce Quality

  - name: synq.git.commits.v1.CommitsService
  - name: synq.dataproducts.v2.DataproductsService
    description: |-
      DataproductsService manages data products — named, owned groupings of data
       assets with a membership definition, a priority and an optional folder.

       Ids are opaque UUIDs supplied by the caller, which makes writes idempotent
       (a retried create converges instead of duplicating). Mutable fields are
       optional on Upsert: a field that is set is written, a field that is omitted is
       left unchanged. Pass the `etag` you last read to guard against overwriting a
       concurrent edit.

       A data product is a leaf in the reference graph — its definition may not
       reference another data product or domain — so membership resolution always
       terminates.

  - name: synq.agent.sre.v1.FeatureRequestService
    description: >-
      FeatureRequestService allows MCP clients to submit feature requests when
      users encounter
       missing capabilities. This is a last-resort service — it should only be used when no
       existing tool can fulfill the user's request.
  - name: synq.agent.recon.v1.SuiteDeploymentService
    description: |-
      SuiteDeploymentService is the platform plane of reconciliation.

       SuiteConfigService is the developer/authoring sandbox (edit, version, run
       ad-hoc with your own credentials — preview-only, no Entity, no Run, no
       Issue). A deployment is what SYNQ actually runs on the workspace's behalf:
       a frozen snapshot of a suite config, mapped to workspace-level SYNQ
       integrations, optionally scheduled or triggerable by API.

       Identity: every deployment has a stable deployment_id (UUIDv7) assigned on
       first promote. It survives re-promotes, schedule/mapping changes, and
       pause/resume. Downstream AssetCommand / RunCommand publication keys off
       deployment_id so Entity identity does not fragment on promote churn.
  - name: synq.agent.recon.v1.YamlService
    description: >-
      YamlService provides stateless conversion between YAML config format and
      proto.
       This is useful for UI editors that need to display/edit suite configs as YAML.

  - name: synq.owners.v1.OwnersService
    description: |-
      OwnersService manages owners and their ownerships — the "alert routing as
       code" surface. An owner is a named responsible party with notification
       channels (contacts); an ownership assigns a set of assets to an owner and
       configures the alerts routed to it. Owner is the resource, ownership its
       sub-resource: an ownership is meaningless without its owner, and deleting an
       owner deletes its ownerships.

       Ids are opaque UUIDs supplied by the caller, which makes writes idempotent (a
       retried create converges instead of duplicating). Mutable fields are optional
       on the Upsert calls: a set field is written, an omitted field is left
       unchanged. Pass the `etag` you last read to guard against overwriting a
       concurrent edit.

       Related: `synq.dataproducts.v2.DataproductsService` (an ownership can own a
       whole data product), `synq.alerts.v1.AlertsService` (how the configured alerts
       are reported), and `synq.users.v1.UsersService` (resolve the users behind
       `UserContact` and Slack/Teams mentions).
  - name: synq.domains.v2.DomainsService
    description: >-
      DomainsService manages data domains — named areas of ownership that group
      the
       assets, data products and sub-domains belonging to one part of the business.

       Ids are opaque UUIDs supplied by the caller, which makes writes idempotent
       (a retried create converges instead of duplicating). Mutable fields are
       optional on Upsert: a field that is set is written, a field that is omitted is
       left unchanged. Pass the `etag` you last read to guard against overwriting a
       concurrent edit.

       A domain may contain other domains and data products, so membership resolution
       is recursive. Every write that adds such a reference — including a change of
       `parent_id` — is rejected if it would close a loop, so a definition can always
       be resolved in finite time.

         The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
         restricting to that range, we ensure that we can convert to and from [RFC
         3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.

         # Examples

         Example 1: Compute Timestamp from POSIX `time()`.

             Timestamp timestamp;
             timestamp.set_seconds(time(NULL));
             timestamp.set_nanos(0);

         Example 2: Compute Timestamp from POSIX `gettimeofday()`.

             struct timeval tv;
             gettimeofday(&tv, NULL);

             Timestamp timestamp;
             timestamp.set_seconds(tv.tv_sec);
             timestamp.set_nanos(tv.tv_usec * 1000);

         Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.

             FILETIME ft;
             GetSystemTimeAsFileTime(&ft);
             UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;

             // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
             // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
             Timestamp timestamp;
             timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
             timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));

         Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.

             long millis = System.currentTimeMillis();

             Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
                 .setNanos((int) ((millis % 1000) * 1000000)).build();


         Example 5: Compute Timestamp from Java `Instant.now()`.

             Instant now = Instant.now();

             Timestamp timestamp =
                 Timestamp.newBuilder().setSeconds(now.getEpochSecond())
                     .setNanos(now.getNano()).build();


         Example 6: Compute Timestamp from current time in Python.

             timestamp = Timestamp()
             timestamp.GetCurrentTime()

         # JSON Mapping

         In JSON format, the Timestamp type is encoded as a string in the
         [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
         format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
         where {year} is always expressed using four digits while {month}, {day},
         {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
         seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
         are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
         is required. A proto3 JSON serializer should always use UTC (as indicated by
         "Z") when printing the Timestamp type and a proto3 JSON parser should be
         able to accept both UTC and other timezones (as indicated by an offset).

         For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
         01:30 UTC on January 15, 2017.

         In JavaScript, one can convert a Date object to this format using the
         standard
         [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
         method. In Python, a standard `datetime.datetime` object can be converted
         to this format using
         [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
         the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
         the Joda Time's [`ISODateTimeFormat.dateTime()`](
         http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
         ) to obtain a formatter capable of generating timestamps in this format.
    google.protobuf.Duration:
      type: string
      format: duration
      description: |-
        A Duration represents a signed, fixed-length span of time represented
         as a count of seconds and fractions of seconds at nanosecond
         resolution. It is independent of any calendar and concepts like "day"
         or "month". It is related to Timestamp in that the difference between
         two Timestamp values is a Duration and it can be added or subtracted
         from a Timestamp. Range is approximately +-10,000 years.

         # Examples

         Example 1: Compute Duration from two Timestamps in pseudo code.

             Timestamp start = ...;
             Timestamp end = ...;
             Duration duration = ...;

             duration.seconds = end.seconds - start.seconds;
             duration.nanos = end.nanos - start.nanos;

             if (duration.seconds < 0 && duration.nanos > 0) {
               duration.seconds += 1;
               duration.nanos -= 1000000000;
             } else if (duration.seconds > 0 && duration.nanos < 0) {
               duration.seconds -= 1;
               duration.nanos += 1000000000;
             }

         Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.

             Timestamp start = ...;
             Duration duration = ...;
             Timestamp end = ...;

             end.seconds = start.seconds + duration.seconds;
             end.nanos = start.nanos + duration.nanos;

             if (end.nanos < 0) {
               end.seconds -= 1;
               end.nanos += 1000000000;
             } else if (end.nanos >= 1000000000) {
               end.seconds += 1;
               end.nanos -= 1000000000;
             }

         Example 3: Compute Duration from datetime.timedelta in Python.

             td = datetime.timedelta(days=3, minutes=10)
             duration = Duration()
             duration.FromTimedelta(td)

         # JSON Mapping

         In JSON format, the Duration type is encoded as a string rather than an
         object, where the string ends in the suffix "s" (indicating seconds) and
         is preceded by the number of seconds, with nanoseconds expressed as
         fractional seconds. For example, 3 seconds with 0 nanoseconds should be
         encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
         be expressed in JSON format as "3.000000001s", and 3 seconds and 1
         microsecond should be expressed in JSON format as "3.000001s".

      title: Header

        Header is one HTTP header of an attempt.

         A header whose value carries a credential is never returned, on either the
         request or the response side. That covers headers you configured as secret,
         credentials held for the destination, and the standard credential-bearing
         names (`Authorization`, `Proxy-Authorization`, `Cookie`, `Set-Cookie`,
         `X-Api-Key`, `X-Auth-Token`) whatever their contents — a destination echoing
         its own authorization header back is withheld too.

         Signature headers are returned in full: `X-Coalesce-Signature` is a digest of
         the body and `X-Coalesce-Timestamp` is a timestamp, neither of which is the
         signing secret, and the exact bytes are what you need to reproduce a
         verification that failed.
