Hey @akhilesh 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: > [@Getting Invalid request : Redirect URI mismatch error](https://devforum.zoom.us/t/-/10484): > > Description I’m getting a Redirect URI mismatch error when trying to get an access token after getting the code. It’s probably because I misunderstood how redirect URI works. I tried the following: Exact same URI as in app settings Same URI that I provided in oauth/authorize call when getting the code I’m getting the same error every time.

Hey @akhilesh, Please checkout my post here: > [@'Invalid request : Redirect URI mismatch.' despite using ngrok](https://devforum.zoom.us/t/invalid-request-redirect-uri-mismatch-despite-using-ngrok/26106/4): > > Hey @Nad, Let me know if this helps explain things: The Redirect URI needs to be the same URI from the authorization (install URL) through to the Get Access Token request. So with these URLs set: When I go to install the app from the “Activation” page, it defaults the redirect URI to the one specified in the “Redirect URL for OAuth” input: https://zoom.us/oauth/authorize?response\_type=code&client\_id=ztmR8sxaSBGZ66b5laR7Ag&redirect\_uri=https://zoom.u… If that does not help, please share your the redirect url you are using so I can help debug.

Hi @akhilesh, Can you also please whitelist the full Redirect URL as well (…/services/apexrest…) in addition to the main domain, and let me know if you’re still experiencing the error? Thanks, Will ---

Hey @akhilesh, I’m getting a 500 error when I try to access your redirect URL. Can you confirm this is publicly accessible and isn’t experiencing any internal server errors? Thanks, Will ---

Hey all figured this out with the help of Will, we need to make sure redirect url,white list has “slash” in the end like below in market place app. Example: “[https://zoom.us/”](https://zoom.us/%E2%80%9D) ========================================================= Also make sure if you are using state in your URL while getting OAuth Code use the same state in getting access token as well. For example: if you are using some thing like below to get Authorization Code [https://zoom.us/oauth/authorize’+’?response\_type=code’+’&client\_id=xxxxxxxxxxxxxx’+’&redirect\_uri=‘https://zoom.us/’+’?state=’+‘test’](https://zoom.us/oauth/authorize'+'?response_type=code%27+%27&client_id=xxxxxxxxxxxxxx%27+%27&redirect_uri=%27https://zoom.us/%27+%27?state=%27+%27test%27) Make Sure you do the same state while calling access token end point [https://zoom.us/oauth/token’+’?grant\_type=authorization\_code’+’&code=’+OAuthCode+’&redirect\_uri=’+‘https://zoom.us/’+’?state=’+'test](https://zoom.us/oauth/token'+'?grant_type=authorization_code%27+%27&code=%27+OAuthCode+%27&redirect_uri=%27+%27https://zoom.us/%27+%27?state=%27+%27test)’ I wish the documentation is a little clear on state stuff as well Thanks! ---
