**Description** I am having the 500 Internal Server Error when I launch the App Authorisation using OAUTH2 app in order to get access token. My email and password are correct(can be signed in at Zoom), and it is the same email as the developer email field in Zoom OAUTH2 app. Th redirect uri are the same too. **Error** ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/4/4abcd0f52e04d6f9ab143758a71be30de93ecc7c.png) **Which App Type (OAuth / Chatbot / JWT / Webhook)?** I am using OAUTH app **Which Endpoint/s?** This is the url/ the API that I am using ‘[https://zoom.us/oauth/authorize?response\_type=code&client\_id=XXXXX&redirect\_uri=$zmEncodedWSurl](https://zoom.us/oauth/authorize?response_type=code&client_id=XXXXX&redirect_uri=%24zmEncodedWSurl)’ **How To Reproduce (If applicable)** Steps to reproduce the behavior: ``` var url ='https://zoom.us/oauth/authorize?response_type=code&client_id=0C4XBizXRNaLaoAs1BENw&redirect_uri=$zmEncodedWSurl'; final callbackUrlScheme = 'foobar'; final result = await FlutterWebAuth.authenticate( url: url, callbackUrlScheme: callbackUrlScheme); ``` ---

I’m seeing this as well. Surprised no mention on [https://status.zoom.us/](https://status.zoom.us/) - seems to be an issue on Zoom’s end. ---

Hey @okzoomer, @gohsyang, We are aware of this issue, it will be fixed this weekend. Current work around is to login first here: [zoom.us/signin](http://zoom.us/signin) and then go back to authorize the app. Apologies for the inconvenience, Tommy ---

Hi Tommy, Am new to using Zoom APIs and first blocker is in OAuth itself. I’m using Postman to try the APIs and in token generation process get 500 internal server error. I am already logged into Zoom using both Chrome and Safari, not sure how to implement above recommended workaround in Postman. Will appreciate help. ---

Hi, I encountered a similar issue of 500 error when I tried to authorize Slack-Zoom integration on Slack. The steps are below: 1. Type `/zoom` on a random slack channel. 2. Click **“Authorize Zoom”** link and open a Zoom sing-in page on Google Chrome. 3. Click **“Sign-in with SSO”** and type our domain name. (Using Okta as a IDaaS) 4. Open a `slack.com` page which requires authentication. It says **“Zoom is requesting permission to access the NESIC社内 Slack workspace.”** (“NESIC社内” is the name of our workspace.) 5. Click “Allow” and move to `application.zoom.us` 6. It says > “Authorization Failure. > 500 - INT\_db8ab08610781134” (See the attached screenshot.) ![failed](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/2X/7/78e9b99518b56e21c2c75edf8cf7fd89dc633a4a.png) I checked the install status of the integration at [App Marketplace](https://marketplace.zoom.us/user/installed), and found it had successfully installed (subscribed) into my zoom account. I found some colleagues in our company encountered the same authorization issue above. I wonder if someone could tell me the additional information to solve the issue. Thanks in advance.

Hey @terovn, Thank you for reaching out to the Zoom Developer Forum. I just have a couple of questions to get us started: 1. Are the steps to reproduce the same as above? > [@mkawamura](#): > > - Type `/zoom` on a random slack channel. > - Click **“Authorize Zoom”** link and open a Zoom sing-in page on Google Chrome. > - Click **“Sign-in with SSO”** and type our domain name.

It says **“Zoom is requesting permission to access the NESIC社内 Slack workspace.”** (“NESIC社内” is the name of our workspace.) > - Click “Allow” and move to `application.zoom.us` > - It says 1.
