Facebook OAuth2 Custom Token

So, I had this working for a couple of months and then all of a sudden it stopped. I thought it was because I needed to initialize the call again in order to refresh the access token. But, that didn’t fix it!

Here’s my current set up. I had it differently and changed it to this. However this isn’t working either.

I try initializing it with a different code each time but I keep getting this error:

"There was an issue setting up your call.

The service this service just returned an error (HTTP 400). Please consult their documentation to ensure your call is setup properly. Raw error:

{"error":{"message":"Invalid verification code format.","type":"OAuthException","code":100,"fbtrace_id":"AG3AfTBH1oPOH4eAfIkMYjg"}}"

Have you been able to get a token back from the token endpoint when using a tool like Postman? Also, I’ve read the code is valid for only 10mins so perhaps that is expired?

I do it here and haven’t had any problems. One thing that is different in yours is that you try to do the exchange code in the API with Authentication Oauth2 Custom Token. Remove this authentication by leaving it as None, and try to make the call the same as mine.
