Error:invalid_client

[will.zoom (Will)]

Hi @mark.krawec,

Thanks for reaching out about this, and happy to help.

It sounds like you’ve already seen our guide for retrieving an access token, right?
https://marketplace.zoom.us/docs/guides/auth/oauth

If you’re still having trouble, a few things to double check:

• You’ve successfully created an OAuth App to generate a Client ID and Client Secret
• You’re grabbing the code parameter from the redirect URL after hitting the user installation URL (install button, testable URL)
• You’re including the required Authorization header in your request

Once you’ve double checked these things, I also recommend checking out this thread:

"Invalid client_id or client_secret"

Hey @abhilash, Did you include the required Authorization header in your request? "Authorization": "Basic base64Encode(Client_Id:Client_Secret)" (You can base64encode them here. Make sure to include the : in between your client_id and client_secret) It will look something like this "Authorization": "Basic YXNkZmFzZGZha3M6YWRramZiYXNrbGRqZmFzZGY=" Also, you need to change redirection_uri to redirect_uri. Let me know if this works! Thanks, Tommy

Please let me know if this helps!

Best,
Will
