Overview

Package endpointcreds provides support for retrieving credentials from an arbitrary HTTP endpoint.

The credentials endpoint Provider can receive both static and refreshable credentials that will expire. Credentials are static when an "Expiration" value is not provided in the endpoint's response.

Static credentials will never expire once they have been retrieved. The format of the static credentials response:

{
    "AccessKeyId" : "MUA...",
    "SecretAccessKey" : "/7PC5om....",
}

Refreshable credentials will expire within the "ExpiryWindow" of the Expiration value in the response. The format of the refreshable credentials response:

{
    "AccessKeyId" : "MUA...",
    "SecretAccessKey" : "/7PC5om....",
    "Token" : "AQoDY....=",
    "Expiration" : "2016-02-25T06:03:31Z"
}

Errors should be returned in the following format and only returned with 400 or 500 HTTP status codes.

{
    "code": "ErrorCode",
    "message": "Helpful error message."
}
