 Since `1.3.0`, the _dest_ parameter can denote a relative file path, in this case the file will be created relatively to `GITBUCKET_DATA`.
 
 On success, you will receive a `HTTP 200` answer with a body containing `done: FULL_PATH_OF_BACKUP_FILE`.
 
+### HTTP API Authorization
+
+The api uses token authentication. To generate a token:
+
+1. Login to Gitbucket with an administrative account
+2. In the top-right corner, click the user menu
+3. Click `Account Settings`
+4. On the left, click `Applications`
+5. In `Generate new token` enter a description and click `Generate token`
+6. Add the token to your http call, such as with `curl`:
+
+    `curl -i -H 'Authorization: token your_token_value' http://YOUR_GITBUCKET/api/v3/plugins/database/backup`
