The name parameter's value depends on the target resource for the request, namely roles, projects, or organizations. Each resource type's name value format is described below:
roles.get: roles/{ROLE_NAME}. This method returns results from all predefined roles in IAM. Example request URL: https://iam.googleapis.com/v1/roles/{ROLE_NAME}
projects.roles.get: projects/{PROJECT_ID}/roles/{CUSTOM_ROLE_ID}. This method returns only custom roles that have been created at the project level. Example request URL: https://iam.googleapis.com/v1/projects/{PROJECT_ID}/roles/{CUSTOM_ROLE_ID}
organizations.roles.get: organizations/{ORGANIZATION_ID}/roles/{CUSTOM_ROLE_ID}. This method returns only custom roles that have been created at the organization level. Example request URL: https://iam.googleapis.com/v1/organizations/{ORGANIZATION_ID}/roles/{CUSTOM_ROLE_ID}
Note: Wildcard (*) values are invalid; you must specify a complete project ID or organization ID.
Authorization requires the following IAM permission on the specified resource name:
iam.roles.get
Request body
The request body must be empty.
