Trying to use the echosign API with oauth2
OAuth is a widely used framework for allowing users to authorize API access. Adobe Sign's implementation complies with the OAuth 2.0 specification, described in this RFC.
This is a direct quote from the OAuth documentation for echosign, but I cannot seem to use the grant type "client_credentials", as the endpoint only responds with the following.
{
"error_description": "Invalid grant_type client_credentials",
"error": "invalid_request"
}
Here is an example of my request that results in this error message
POST /oauth/token HTTP/1.1
Host: secure.eu1.echosign.com
Authorization: Basic **********************************
Content-Type: application/x-www-form-urlencoded
Cache-Control: no-cache
grant_type=client_credentials
As client_credentials is part of the spec, and I would very much like to use it for the application I have in mind, what would be my steps to proceed?
Is there a way for me to enable client_credentials for my application?
P.s.
These documentations could do with an update that states clearly that having the correct region (i.e. secure.{region}.echosign.com) in the oauth URI is imperative, and that you may receive invalid_request if you're in the wrong region.
