Issue Generating Refresh Token with OAuth Code Flow
Hello, I have been struggling a bit with getting a refresh token or any success response at all from the endpoint 'https://api.dropboxapi.com/oauth2/token' when following the guide here https://devel...
Given your redactions and descriptions, it seems like you're sending a parameter with the name being your app key and the value being your app secret, however that is not the correct formatting. When calling /oauth2/token to exchange the authorization code for an access token/refresh token with the code flow like this, you should send a parameter named "client_id" with the value being your app key, and a parameter named "client_secret" with the value being your app secret. You would do that the same way you already have a parameter named "code" with the value being the authorization code string.
(Note that it's also possible to send the app key and secret as "Basic" authorization, which is what the example in the documentation does using the "-u" curl flag, but that would be encoded and formatted differently. I recommend just using the parameters as described above for simplicity.)

The lowest section is my app key and app secret (in that order).
Is it possible to make this POST request to this endpoint in the way I am trying?

Hi ImpulseWebDev,
No, It's not! Where you read that you need to post parameter carrying name equal to your app key?
Next the curl examples, there are lists of possible parameters! You have to choose something from there. Possible parameters for passing app key and secret are client_id and client_secret. Alternative way is passing them in form "<client_id value>:<client_secret value>" as base authentication.
Hope this gives direction.
Hello and thanks for the reply.
My apologies, I am not very familiar with Curl request syntax, however I was attempting to reproduce the example from the dropbox endpoint docs here:curl https://api.dropbox.com/oauth2/token \ -d code=<AUTHORIZATION_CODE> \ -d grant_type=authorization_code \ -d redirect_uri=<REDIRECT_URI> \ -u <APP_KEY>:<APP_SECRET>
The last portion '<APP_KEY>:<APP_SECRET>' was why I attempted that method. I have since updated to use the two params suggested, however any idea what would trigger this response? I did return to my app console to verify both key and secret are up to date
Final reply: The params suggested do work in my non-postman fetch request and return the success response outlined in the docs. That gets me through- Thank you again!
