Dropbox generate Auth Token thru java
Hi,
I am able to generate Access Token manually thru the dropbox website which is working fine. But expires after a few hours, Is there any method in Java that can generate access token program...
Thank you very much for your response. I have generated an access code from oauth2. Its asking me to enter this code into CLIENTSDATA (which is the app i created in dropbox). I don't know where to enter this Access Code in ClientsData. Given below are the screenshots of the access code from OAUTH2 and ClientsData settings/permissions. Where do i enter this access code in ClientsData settings/permissions?

Dropbox StaffJagan Tirumalai That "access code" is also known as the "authorization code". It should not be copied into the app's settings on the App Console; it should be copied back into the app itself. For example, refer to this line in the Java SDK example code that reads the authorization code back into the app so it can then finish the authorization flow.
Hi Greg-DB
I have tried executing with ScopeAuthorize.java in my java program. When running the script its asking me to use DbxPKCEWebAuth instead of DbxWebAuth. So i have modified the code in ScopeAuthorize.java (local version) with DbxPKCEWebAuth. After changing with DbxPKCEWebAuth i am getting the following error when validating the access code.
Debug Stmts from ScopeAuthorize.java
After authorize method
Inside authorize method
in Oauth2 flow1
2. Click "Allow" (you might have to log in first).
3. Copy the authorization code.
Enter the authorization code here: 5dT79_yz4OAAAAAAAAACesA41RjYlsBmJaj9cl8HDkI
After code.trim :5dT79_yz4OAAAAAAAAACesA41RjYlsBmJaj9cl8HDkI
Before finishfromcode
Error in DbxWebAuth.authorize: {"error": "invalid_grant", "error_description": "invalid code verifier"}
I am not able to attach my java program and ScopeAuthorize.java (with my changes) to this forum. ScopeAuthorize.java is failing at line 133 which is given below.
DbxAuthFinish authFinish = webAuth.finishFromCode(code); Line 133
which i have changed it to the following (note PKCEwebAuth instead of webAuth).
System.out.println("Before finishfromcode"); --> its working up to this point
DbxAuthFinish authFinish = PKCEwebAuth.finishFromCode(code); --> its failing here
System.out.println("After finishfromcode");

Hi Jagan Tirumalai,
Based on the Auth URL you have provided, it looks like you are following a PKCE auth flow, which would explain why the suggestion to use DbxPKCEWebAuth is being made.
If the intention is to use PKCE, we would recommend taking a look at this example instead.
Hi,
Thank you for your suggestion. The class PkceAuthorize.java doesn't generate or return any access_token. How do i go about using this class?
All i need is access_token to be generated without manual intervention, so that i can automate the dropbox . Is there such a method in java dropbox api?
