Error in Refreshing with refresh tokens

API and Webhooks
6

Thanks @ezhilvelan006,

Can you double check you are following the correct flow?

Here is the flow from start to finish on a per install basis,

  1. Go to url below (or click install app button on app dashboard) to authorize your app,

GET https://zoom.us/oauth/authorize?response_type=code&client_id={YOUR_CLIENT_ID}&redirect_uri={YOUR_REDIRECT_URI}

Grab the authorization code in the redirect url https://yourRedriectUrl.com?code={AUTHORIZATION_CODE}

  1. Then request an access token

POST https://zoom.us/oauth/token?grant_type=code&redirect_uri={YOUR_REDIRECT_URI}&code={AUTHORIZATION_CODE}

HEADERS: {"Authorization": "Basic BASE64ENCODED(CLIENT_ID:CLIENT_SECRET)"}

This will give you an access_token and refresh_token

The access_token is different per user and lasts for one hour.
The refresh_token is different per user and lasts for 15 years (unless you refresh access_token in which it becomes invalid and you get a new one)

You want to store both of these.

Now let’s say your access_token is no longer valid

  1. You need to refresh the access_token,

POST https://zoom.us/oauth/token?grant_type=refresh_token&refresh_token={REFRESH_TOKEN}

HEADERS: {"Authorization": "Basic BASE64ENCODED(CLIENT_ID:CLIENT_SECRET)"}

Now this will return a new access_token AND a new refresh_token. You need to store these new values as the old ones are now invalid.

You can use the access_token to call Zoom API’s, and when the access_token is expired, repeat step 3 for that user to get a new access_token and refresh_token.

Let me know if this helps, otherwise I will look into your account specifically.

Thanks,
Tommy
