When a document goes through the various failure statuses, what is the recommended way to handle it? Should the document be deleted before another upload is attempted? Will subsequent uploads trigger a DuplicateResource error if not? ---

H @jmtichell – when a document fails approval, we recommendation surfacing the failure reason to the User and prompting them to upload a different document which is valid. There isn’t a way to remove a Document. A `DuplicateResource` error is returned when the same doc is uploaded again. Hope that helps! ---

How does Dwolla determine if the document is a duplicate? ---

Ah, sorry for the confusion – when I saiid “the same doc” I meant to say the same `file`. For example, if a Document is uploaded and fails with a `"ScanNotReadable"` error, the user can upload a picture of the same document, but not upload the same file that was previously uploaded which failed verification. ---

Thank you for the help. If a user were to do the following, would step #3 succeed - or would it fail since the filename is the same? 1. User uploads a .jpeg of a driver’s license named my\_license.jpeg 2. Dwolla can’t read the file and returns a “ScanNotReadable” error. 3. User uploads a NEW scan of the drvier’s license also named my\_license.jpeg. ---

In this case, #3 would succeed in uploading since the actual file would be different. ---

I’m still having difficulties with this. When I upload the failure test license, I’m not able to re-upload the file (to trigger/test the customer\_verification\_document\_failed webhook) and receive this response when I try and do so: ` {"code":"DuplicateResource","message":"Document already exists.","_links":{"about":{"href":"https://api-sandbox.dwolla.com/documents/115e4a49-ea9f-4842-9df1-872111c13262","type":"application/vnd.dwolla.v1.hal+json","resource-type":"document"}}}` I’m retrieving the URL that I am uploading the file to from the Dwolla Retreive Customer endpoint: body[’\_links’][‘verify-with-document’][‘href’] Based on the earlier responses, I would expect this to return a ScanNotReadable or other error, not that the document is a duplicate. ---

@sherya I’m having similar issues testing the failure and success of documentation. We have a mobile app only, so I save the images to my photo area. Should this work? ---

Hi @jmtichell – it sounds like the same `failed` sample doc is being uploaded twice. If so, the second upload will fail with the `DuplicateResource` error. The first document did get rejected with a `ScanNotReadable` reason. You’d now have to upload the `approved` sample doc to move the Customer into a verified status. If you were looking to trigger the `customer_verification_document_failed` webhook, you’d have to create a new Customer in document and upload the sample `failed` doc.
