To allow your application to integrate with your ZOHO Creator applications, you must register it with ZOHO
Generate Access Token and Refresh Token :
Once the client application receives an authorization code, it can exchange for an access token by making the following request
Refresh the Access Token :
Access tokens expire in an hour. Client applications must make the following request and use their user's refresh token to generate another access token
NOTES :
A maximum of 5 refresh tokens can be generated per minute.
A user in an organization can have a maximum of 20 refresh tokens, and each refresh token can have a maximum of 30 active access tokens at any time.
When the request is made to generate the 31st access token, the authorization server will delete that user’s first access token. Similarly, when the request is made to create the 21st fresh token, the authorization server will delete that user’s first refresh token.
