Data Catalog API methods that are related to Data Catalog search and metadata are deprecated and will be discontinued on January 30, 2026. See Transition from Data Catalog to Dataplex Universal Catalog. Methods that are related to policy tags and policy tag taxonomies are not deprecated.
Sets an access control policy for a resource. Replaces any existing policy.
Supported resources are:
Tag templates
Entry groups
Note: This method sets policies only within Data Catalog and can't be used to manage policies in BigQuery, Pub/Sub, Dataproc Metastore, and any external Google Cloud Platform resources synced with the Data Catalog.
To call this method, you must have the following Google IAM permissions:
datacatalog.tagTemplates.setIamPolicy to set policies on tag templates.
datacatalog.entryGroups.setIamPolicy to set policies on entry groups.
HTTP request
POST https://datacatalog.googleapis.com/v1/{resource}:setIamPolicy
Path parameters
Parameters
resource
string
REQUIRED: The resource for which the policy is being specified. See Resource names for the appropriate value for this field. It takes the form projects/{project}/locations/{location}/entryGroups/{entrygroup}.
Request body
The request body contains data with the following structure:
REQUIRED: The complete policy to be applied to the resource. The size of the policy is limited to a few 10s of KB. An empty policy is a valid policy but certain Google Cloud services (such as Projects) might reject them.
OPTIONAL: A FieldMask specifying which fields of the policy to modify. Only the fields in the mask will be modified. If no mask is provided, the following default mask is used:
paths: "bindings, etag"
This is a comma-separated list of fully qualified names of fields. Example: "user.displayName,photo".
Response body
If successful, the response body contains an instance of Policy.
