#Pipeline APIs

List the Hub Pipelines visible from a Workspace Namespace or retrieve a requested set of Pipelines in one batch. Text search is performed by clients over the list response; this endpoint does not accept a server-side search expression.

#/api/v1alpha1/pipelines

#get List Hub Pipelines

Returns the Pipelines visible from the requested Namespace. Visibility filtering happens before pagination. The API does not provide a server-side text-search parameter; clients can search or filter the returned list. This operation requires list permission on hub.tekton.dev/resources.

#Parameters

• namespace (in query): string

  Workspace Namespace used for authorization and catalog visibility filtering. It must be a DNS-1123 label. When omitted, the response uses the legacy unscoped catalog view. Generated apiPath and manifestURL values preserve this parameter.

• includeContent (in query): boolean

  Whether list items include README and manifest content. Detail and batch responses always include content.

• offset (in query): integer

  Zero-based offset applied after visibility filtering.

• limit (in query): integer

  Maximum number of items to return. When supplied, the server caps it at config.maxBatchQuerySize, which defaults to 200. When omitted, all items after offset are returned.

#Response

• 200 HubResourceList: The requested Hub resources.
• 400 ErrorResponse: The Namespace, query parameter, path, or request body is invalid.
• 401 ErrorResponse: The Authorization header is missing or the Bearer token is invalid.
• 403 ErrorResponse: The authenticated caller is not allowed to access Hub resources in the Namespace.
• 404 ErrorResponse: The Namespace or resource does not exist, or the catalog is not visible from the Namespace. Hidden catalogs intentionally use the same status as missing resources.
• 500 ErrorResponse: Indexed README or manifest content could not be resolved.
• 503 ErrorResponse: The Hub index, authentication service, or Namespace lookup service is temporarily unavailable.

#post Batch-query Hub Pipelines

Returns the requested Pipelines in request order. The request is atomic: if any resource is missing or not visible from the Namespace, the entire request returns 404. The default deployment accepts at most 200 entries and limits the JSON body to 1 MiB. This operation requires list permission on hub.tekton.dev/resources.

#Parameters

• namespace (in query): string

  Workspace Namespace used for authorization and catalog visibility filtering. It must be a DNS-1123 label. When omitted, the response uses the legacy unscoped catalog view. Generated apiPath and manifestURL values preserve this parameter.
