Refresh token problem

[hoss_4807]

I'm trying to generate a refresh token to update a User access token
via this API:

https://api.ebay.com/identity/v1/oauth2/token

I set all headers and information, but it returns:

{"error":"invalid_grant","error_description":"the provided authorization refresh token is invalid or was issued to another client"}

I'm having the exact same issue, followed everything to the letter, checked and double checked all the values but still get the same error as you

I have the same problem too. Since Friday I've only got the error message. Have you already found a solution?

I am having the same problem as well, but just on a few listings. Has anyone figured out why
