OAuth 2.0 for ServiceNow integration

Hi everyone,

I made an integration between Azure DevOps and ServiceNow via Basic Authentication where from ServiceNow, I trigger a new release creation. Everything works but now I have to change the authentication to OAuth 2.0.

I have followed this documentation https://docs.microsoft.com/en-us/azure/devops/integrate/get-started/authentication/oauth?view=azure-devops but I see end user needs to accept application authorisation manually and I need an automatic process.

Thoughts?

Thanks in advance.
