Hello, I am using OAuth token to schedule meeting using zoom api. But after 1 hour access token expired and when I try to generate new access token with old refresh token It gives the following issue: Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: `POST https://zoom.us/oauth/token` resulted in a `401 Unauthorized` response: {“reason”:“Invalid Token!”,“error”:“invalid\_request”} I am working in PHP. ---

Hey @marketing4 Thanks for posting on the Zoom Devforum! I am still learning, but I will try my best to help answer your question. 🙂 Checkout these related threads that may have the answer you are looking for: > [@Failed to find the refresh Token.

Hey @marketing4, You should have received an email or be able to view a DM from the top right hand side of your Forum account/dropdown menu. If you still have trouble seeing the DM, you can send us an email at [developersupport@zoom.us](mailto:developersupport@zoom.us). Please include the value you’re passing for your authorization header with us either of these places (do not post this here, as this contains sensitive credentials). This will help us to debug! Thanks, Will ---

Hi @marketing4, Thanks for sharing this. I’m not seeing any issues with your Authorization headers. I think there is likely still an issue with the `refresh_token` value you’re passing in the form\_params for your refresh request. Can you please send us an email to [developersupport@zoom.us](mailto:developersupport@zoom.us) with the values you’re passing for your refresh\_token? We should be able to check our logs to look into this further. Please do not share this here, as these are sensitive details. Thanks, Will ---
