I notice you are using the header “Content-Type:application/x-www-form-urlencoded” which isn’t listed in the documentation around refresh listed on this page:

[https://devdocs.zoom.us/docs/oauth-with-zoom](https://devdocs.zoom.us/docs/oauth-with-zoom)

It appears to have solved our problem, so you may want to update the docs accordingly.&nbsp; Also on that page, the refresh token section makes reference to the revoke endpoint, which we noticed, but could be quite misleading for folks.

Thanks!
