Hi, @mladen,
Thank you for posting in the Developer Forum. Are you able to confirm you are always using the newest refresh_token that is returned with every [refresh request] ?
I’ve linked a similar Developer Forum post that may be a useful point of reference :
Hi @donte.zoom Thanks for the quick response. No i don’t use two accounts, also i don’t use the scenarios from the tread you are referring. My postman gives me the error on newly created refresh token (as you can see from the screenshots).
I tried different ways to pass app key and secret with same result.
Please make sure that you are using a Content-Type header of application/json. Further, instead of using the --data argument to send POST body data to the endpoint, you’ll want to set the values as query parameters instead.
Here’s an example of how the cURL command would look:
Great! I’m glad to hear that it’s working now. I’ll go ahead and close this topic now but feel free to open a new topic if you encounter any further issues or questions.
