How does ServiceNow auto generates access tokens after the first access token is manually generated

If the grant type is auth code:

1. How does serviceNow auto generates new access tokens after they get expired based on the valid refresh token ?

Hi @Lokesh5 , 

Token Expiration and Validity is as follows:

• Access Token: By default, an instance issues access tokens with a 30-minute lifespan in the scenario where the instance is the OAuth provider.
• Refresh Token: By default, an instance issues refresh tokens with a 100-day lifespan in the scenario where the instance is the OAuth provider.

By doing the below steps refresh token gets generated and the expiration date can be extended accordingly.
