Dropbox API - Invalid redirect URI (Error 400) with React Native Expo
I am building a React native app and trying to integrate the Dropbox API.
I'm following expo's app auth guide: https://docs.expo.dev/guides/authentication/#dropbox
and I have the App registered with a scheme in the redirect URI's as: com.kkanchev94.esignapp://oauth
and the same one registered and build with that scheme in the mobile app, but I keep receiving the same error over and over.
Tried with with a different schemes - which I registered on the Dropbox API side as well, but without any luck.
Has anyone faced the same challenges with the invalid redirect URI for building on a mobile app and
how should I go about resolving it. Much appreciated!!
I was able to figure it out, what you need to do is divide your scheme into two parts like such:
Scheme registered and built in the mobile app - com.kkanchev94.esignapp://oauth
Use the code from https://docs.expo.dev/guides/authentication/#dropbox
- on scheme divide your redirect URI as the following template:
redirectUri: makeRedirectUri({scheme: "com.kkanchev94.esignapp",path: "oauth",}),Omit the "://", it will be added automaticallyHope that helps, this is for an Expo built project.
