Step 4: Generate Access Token From Refresh Token
Access tokens have limited validity, typically expiring within one hour. While valid, the access_token offers unlimited usage. Once it expires, your application needs to use the refresh_token to request a new one.
Use the following POST request with the specified parameters to obtain a new access_token :
https://accounts.zoho.com/oauth/v2/token?
| Parameter | Description |
|---|---|
| refresh_token * | refresh_token obtained in the previous step |
| client_id * | client_id obtained during Client Registration |
| client_secret * | client_secret obtained during Client Registration |
| redirect_uri * | This parameter should be same redirect_url used while registering the client |
| grant_type * | refresh_token |
