Implemeting Notion OAuth2
Hey! I have tried everything now to implement the Oauth2 flow for Notion, but I always get this error. Anyone has any ideas what could cause it?

I also get this error on the client
It is receiving an incorrect client_id and client_secret
That's really the only reason I know of that notion will respond with that error code
Could this be because they want it encoded in Base64 and BetterAuth doesn't do that?
better-auth should be doing it internally.
If its not, then something is wrong about that.
Not sure. I used Remix OAuth2 before and did not change anything apart from the callback URL as specified in the OAuth2 plugin here
I haven't used better-auth's generic oauth2 implementation so I can't offer more help than what I have already stated. So either better-auth isn't base64 encoding the id and secret or your id and secret are wrong
try adding
{ authentication: 'basic' } in the configLifesaver! Now I have a email_is_missing error, but it looks like the flow went through. Thanks 🙏
email_is_missing means the oauth is not returning a email in data
try checking the socpes
I think it is because the request to api.notion.com/v1/users/me fails with a 40I. From the error it seems like Better-auth doesn't pass the authorization header when requesting, which Notion requires
ok try this
it is the endpoint which returns user data?
Yup, it is. https://developers.notion.com/reference/get-self

you can just implement your custom function if the normal one is not working
getUserInfo(tokens) {...}
access tokens, call the api, return dataThanks! WIll figure that out 🙌
