Dropbox OAuth2 Endpoint not giving refresh Token

[w3Abhishek]

Hey Dropbox Team,

I am using the Dropbox OAuth2 API for my personal project. But after receiving the authorization code from the user through OAuth URL.

I used it to get the access_token and refresh_token but upon sending the authorization code, the API is only sending access_token which get expired and not refresh token.

Now, how I will be able to refresh the access_token after expiration? 

Help me.

Hi @w3Abhishek,

If nothing set explicit as token access type, it's as assumed to be online access type! You need offline access type for refresh token. If you have forgotten set this parameter, just set it on OAuth2 initiation. 😉 Take a look here for possible flow. Note the parameter token_access_type.

Hope this helps.

@w3Abhishek Здравко is correct; you'll need to set token_access_type=offline on the authorization URL in order to receive a refresh token from /oauth2/token. Refer to the following resources for more information:

Thanks Greg-DB and Здравко. Adding token_access_type=offline in my OAuth URL solved the problem.
