is there any Java sdk method to generate access token on the run by taking app key and app secret??

Hello Dropbox team,

As Access token is expiring every 4 hours, we have to regenerate them every 4 hrs. This is becoming difficult to update the access code in my script manually. I'm looking for a Java SDK method that generate access token automatically every 4 hours by taking app key/app secret as input parameters. Could you suggest any sdk method or code sample that I can use to generate access token on the run in my script using app key/app secret.

Any help would be highly appreciated !!

Hi again @Reshma ,

Seems you have misunderstood me. You can't just place one type of token where other type is expected! In Java SDK a DbxCredential object should be used as a proxy (don't ask me why) for refresh token.

Hope it's a bit more clear now.

Hi @Reshma ,

Every supported SDK do this automatically byself (without any additional method/function call). You just have to initialize your client object using refresh token instead of access token. 😉 That's it.

Hope this helps.

Thanks for the suggestion. I have created a Refresh token using this curl

curl https://api.dropbox.com/oauth2/token -d code=<receivedcode>-d grant_type=authorization_code -u <Appkey>:<Appsecret>

Then I have initialized/created drop box client object with Refresh token in place of access token

private static final String REFRESH_TOKEN = "<REDACTED_REFRESH_TOKEN> -u <REDACTED_APP_KEY>:<REDACTED_APP_SECRET>";

// Create drop box client

DbxRequestConfig config = DbxRequestConfig.newBuilder("dropbox/AppToCreateIT's").build();
DbxClientV2 client = new DbxClientV2(config, REFRESH_TOKEN);

But unfortunately this dint work, it is throwing below error
Invalid authorization value in HTTP header "Authorization": "Bearer <REDACTED_REFRESH_TOKEN> -u <REDACTED_APP_KEY>:<REDACTED_APP_SECRET>". Expecting "Bearer <oauth2-access-token>".

pardon If my understanding is wrong , could you please guide me with the exact steps to be followed?

I have taken the below reference to create dropbox client. instead of access token I have used refresh token as per your suggestion

GitHub - dropbox/dropbox-sdk-java: A Java library for the Dropbox Core API.

@Reshma As Здравко indicated, you cannot use a refresh token as an access token. Refresh tokens and access tokens serve different purposes and are not interchangeable. You can find examples of using the authorization flow in the Java SDK here. You can find an example of using a credential with a client to make call here.

Also, for future reference, do not publicly post your refresh token or app secret. I've redacted them from your post. You may want to revoke it for the sake of security.

Thanks. This helps.
