Security Token Service (STS) enables you to request temporary, limited-privilege credentials for Identity and Access Management (IAM) users or for users that you authenticate (federated users). This guide provides descriptions of the STS API. For more information about using this service, see Temporary Security Credentials.
Use this page to mock AWS Security Token Service in your testing and development.
Run our mock API sample using the open source WireMock library, or in the free edition of WireMock Cloud. You'll have a working API server simulating the behavior of AWS Security Token Service, which will allow you to keep building and testing even if the actual API you isn't currently available.
