Which Endpoint/s?

How To Reproduce (If applicable)

  1. Its showing when in callback

Hey @rahul.sharma,

Thank you for reaching out to the Zoom Developer Forum. How are you making this request from your GoDaddy server? Are you using cURL, a programming language, or something else?

Are you able to reproduce this issue when using different REST clients from that environment?


Hello MaxM,
I am using Mattermost with Zoom plugin integration. I have created an app and connected with the api key and secret key. The problem here is zoom is unable to detect the chain of ssl certificate for the domain.

Hey @rahul.sharma,

Do you get this same error when hitting Zoom from Postman, cURL/terminal, etc.? This seems like it’s likely an environment issue.


The issue is with the callback not with the api’s. The api’s are working fine. Only Zoom unable to detect the SSL certificate for the domain. I guess!

Thanks for confirming, @rahul.sharma.

Have you tried checking out a resource such as StackOverflow, etc., for suggestions on this?
