# Error creating Return Labels

 * Hello! After the latest WordPress and WooCommerce updates, the Return Label creation
   stopped working. We set the DHL plugin from SOAP to REST, re-synced the plugin
   but the DHL RETOURE ONLINE service participation number is not populated.
   The
   error message in logs says:
 *     ```wp-block-code
       (    [status] => 400    [body] => {"status":{"title":"Bad Request","status":400,"detail":"0 of 1 shipment successfully printed.","statusCode":400},"items":[{"sstatus":{"title":"Bad Request","status":400,"statusCode":400},"validationMessages":[{"validationMessage":"The service entered is unknown.","validationState":"Error"}]}]})
       ```
   
 * I’ve checked the contract and indeed DHL RETOURE ONLINE service is active.
 * I would need some assistance and an email where I can forward the logs and screenshots.
 * Mit freundlichen Grüßen,

 * Hello [@gabejasper](https://wordpress.org/support/users/gabejasper/) 
   Can you
   check the **DHL Products and Participation Number** within the plugin settings:
   WooCommerce > Settings > Shipping > DHL Paketmake sure to click in “Get account
   settings button” and test again, if it still now working, check the **DHL Retoure**,
   we noticed that somethimes this is returned with wrong value by DHL API, try 
   to change it to 01, or contact the DHL support to check with them what is the
   right values for your account. ( We are following up with them to check why this
   API return wrong values for some accounts )Thanks

 * I’ve checked DHL Products and Participation Number in the plugin settings and
   only DHL PAKET GKP and DHL PAKET INTERNATIONAL gets populated by clicking on ‘
   Get Account Settings’ button. If I manually add the correct participation value
   for DHL Retoure (01), the error is still present:
 *     ```wp-block-code
       Error creating label:Error :The service entered is unknown.
       ```
   
 * I’ll contact DHL support then to check if REST API is active for DHL RETOURE 
   ONLINE service.
   Hope you get it fixed and patched ASAP.Mit freundlichen Grüßen,
