Trying to get through OAuth2 testing in Postman. I am using the Get New Access Token page but it takes me to the “Invalid redirect url (4700)” page. ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/a/ad2fc2f2bec12195faff28f087d72be838b1109d.png) What’s wrong with this setup? Steps to reproduce the behavior: 1. Enter in the same info in Postman but with your own client\_id and client\_secret. It is probably something simple I am not seeing. Thanks for the help! ---

Figured this one out. redirect\_uri goes where it says “Callback URL”, not “[https://myapp.io/zoomcallback](https://myapp.io/zoomcallback)” Also, I think the redirect\_uri has to be an “https” address to fix the redirection however I am not 100% sure about that. I was able to generate a token after changing the Callback URL which is the first problem I was trying to solve here. ---

Hi baifeng1991321, Set Callback URL = “redirect uri”. **Do not set** Callback URL = “[https://zoom.us/oauth/callback](https://zoom.us/oauth/callback)”. “redirect uri” should be something like “[https://www.yourdomain.com/landing\_page\_after\_login](https://www.yourdomain.com/landing_page_after_login)”. The “redirect uri” is the page the user sees AFTER they have logged in successfully to Zoom. Unfortunately I am leaving my house for a few hours so I cannot help any further right now. Good luck! ---

Hey @baifeng1991321, I am well! It looks like your backend is not sending a response to your Angular frontend. Which github sample are you using? [Here are the docs on generating a signature serverside.](https://marketplace.zoom.us/docs/sdk/native-sdks/web/essential/signature) As for your request in Postman, please set the Type to `Bearer` not OAuth 2.0. ![Screen Shot 2020-01-21 at 12.33.50 PM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/1/155eecacb3f89a4e6a57dff78cdb3c1d733c4455.png) Thanks, Tommy ---

@Tommy, Could you help me to zoom oauth test setup in postman? I’m getting `Invalid Request URL (4700)` Error. I’m following tutorial [https://marketplace.zoom.us/docs/guides/authorization/oauth/quickstart](https://marketplace.zoom.us/docs/guides/authorization/oauth/quickstart). It would be great if you are available via team viewer. I’m trying to setup zoom LTI with our LMS system. ---

Hi @deepen, When testing within Postman, please make sure your redirect url matches the one you set within your OAuth app. [https://zoom.us/oauth/token?grant\_type=authorization\_code&code=2LGsWqGOg&redirect\_uri=](https://zoom.us/oauth/token?grant_type=authorization_code&code=2LGsWqGOg&redirect_uri=)**[https://zoom.us](https://zoom.us)** ![Screen Shot 2020-03-26 at 11.55.36 AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/e/e01f2a9160f4ba7bd82dab5eeae50f2a27c42534.png) ---

Thanks @michael_p.zoom for responding. I’m trying to Oauth with zoom. First step as per doc is to get authorize user and second step is retrieve access token of that user. I am getting difficulty in first step. Steps I followed, - Create one Oauth in zoom market place - Set `https://zoom.us` url in redirect url for development and production. - Get client id and secret - Use `https://zoom.us/oauth/authorize?response_type=code&client_id=&redirect_uri=https://zoom.us` to authorize user in web browser and in postman as well. Here, I’m getting `Invalid redirect url(4700)` error. Could you help me to solve this? I can use `ngrok` to build URL which can forward to `localhost` if you can help to setup. Thanks. ---

Hey @deepen, Make sure you have set your redirect url domain ([https://zoom.us](https://zoom.us)) in the whitelist section. ![Screen Shot 2020-03-27 at 11.06.59 AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/9/9a521f49472e130cb1b87516930a5dbc03af925f.png) Thanks, Tommy ---

Thanks @tommy for your response. I did test as per your suggestion and it worked for one time only. It’s not working after I changed redirect\_uri in zoom app config and in local. I roll backed changes. but, no luck. What I did as, - Changed redirect\_url to `https://402f3930.ngrok.io/zoom-integration/` in zoom app and redirect\_url in authentication url. - Whitelisted `https://zoom.us`. ---
