IAM client libraries
Stay organized with collections
Save and categorize content based on your preferences.
The APIs for Identity and Access Management (IAM) are built on HTTP and JSON, so any standard HTTP client can send requests to it and parse the responses.
However, the Google API Client Libraries provide better language integration, improved security, and support for authentication. The client libraries are available in a number of programming languages; they handle all communication with IAM.
Many Google Cloud services also offer Google Cloud Client Libraries, which you can use to manage the allow policies for each service's resources. The Google Cloud Client Libraries offer the same benefits as the Google API Client Libraries, along with a more idiomatic API for each programming language. To learn more, see Client libraries explained.
IAM v1 API
Use the IAM v1 API to manage custom roles, service accounts, and service account keys.
To grant and revoke access to a specific resource, use the getIamPolicy and
setIamPolicy methods in that resource's API to update its allow policy. For a
list of resource types that accept allow policies, see
Resource types that accept allow policies.
To manage deny policies, use the IAM v2 API.
