I feel like maybe people who work in infosec just don't understand how little brain-power the average developer wants to devote to their fancy auth solution.

Scoped API tokens in Atlassian require you to hit a different API endpoint; they don't work with the same endpoint as unscoped tokens […]

Should you blindly trust JWTs for accessing APIs? 😟

You’ve got OAuth 2.0 and #JWT's, but a single misconfiguration in your library can leave you wide open. Join Wesley to see why "standard" validation isn't always enough.

I spent evening to get Microsoft Oauth working for a web site. Turns out the token does not contain email for the user. Which makes it rather useless for login. Did I do something wrong?

Access Token 토큰 만료로 인한 서비스 중지를 막기 위해선 직접 n8n 의 워크플로우에서 주기적으로 토큰을 갱신해주고, RESTful API에 해당 토큰을 넣어주면 된다.
물론 좀 성가실 수는 있지만 n8n을 쓰는 사람이라면 '자동화'에 관심있는 사람이니 이런 토큰 갱신 자동화도 관심있겠지.

물론 n8n내에서 제대로 refresh가 되는 경우도 있겠지만 수백차례 써 본 내 경험에 의하면 거의 대부분 토큰 만료가 발생한다. 특히 테스트 App 인 경우는 100%...

이를 해결하기 위해선...

n8n을 사용하는 분이라면 외부 RESTful API 사용은 필수이고, 이를 위해선 OAuth2를 제대로 이해해야좋다.
이유는 보통 Access Token을 통해 연동하는데 그냥 n8n credential을 사용하면 토큰 만료로 서비스가 중단될 수 있기 때문이다.
