Issue with Auto Refresh Token

[deepikamara]

Hi All,

We are performing an integration using a Spoke in ServiceNow and have configured the oauth_2_0_credentials table to store the OAuth 2.0 credentials. The initial access token was successfully generated, and we set the refresh token lifespan to 8,640,000 seconds in the Application Registry.

However, we are encountering an issue:
Before the access token's expected expiry time, the integration fails in Flow Designer with an authentication error. Once we manually refresh the token, the flow starts working again as expected. Can you please help us.

So you generate fresh access token each time using script and then pass that token to Flow step in actual API call

Hi @Ankur Bawiskar ,

Could you please help me understand why my access token is not working even though it hasn't yet reached its expiry date?

@deepikamara 

refresh token has long expiration, access token has usually 30mins.

It's already recommended to generate the access token using script before consuming the actual endpoint although you are calling the actual endpoint multiple times in 30mins and the access token will be the same for that 30mins.
