OAuth Authentication Errors

If you are getting the following error when trying to make a request to the DocuSign API:

{ "errorCode" : "USER_AUTHENTICATION_FAILED", "message" : "One or both of Username and Password are invalid. Invalid access token"}

you will typically have to go through the Authentication process again to generate a new set of tokens. Make sure you have entered the Integration Key and Client Secret correctly then click the Authenticate button on the Setup screen and follow the prompts to login to DocuSign and generate a new set of tokens. You can follow the instructions in our Getting Started Guide or the Authorization Code Grant video on our Videos page.
