From what I’ve been able find in the Netsuite documentation, it seems that Netsuite’s implementation of OAuth 2.0 requires a manual re-authentication every 7 days when the refresh token expires. Is there any way to get around this limitation? I would like to be able to automate the retrieval of new refresh tokens so that an administrator only needs to set up the integration’s authentication once and the software integrating to Netsuite handles the rest.

I think the format is something like: https://{{accountid}}.suitetalk.api.netsuite.com/services/rest/auth/oauth2/v1/token?grant_type=refresh_token&refresh_token={{REFRESHTOKEN}}
