Authorize.Net OAuth Token endpoint has internal server error.

[TroyW]

I am having a problem with the Authorize.Net API.  When my web application goes to request a new access access token at https://access.authorize.net/oauth/v1/token, posting in grant_type=refresh_token&refresh_token=(my refresh token)&client_id=52aFq3XHuf&client_secret=(my client secret)

The API endpoint responds with:

{"response":{"rmsg":"Internal System Error"}}

My web application has been working fine for years, then this cropped up earlier today.  Any idea what's going on?

Troy,

I don't know what is going on. See if the raw response has more information about the error message. I have found that calling the Developer support people at AN, and telling them the error, often elicits more understanding. They are familiar with common errors (in my experience).

HTH!
