Document Check

Check your clients documents to extracts details and confirm their authenticity.

Run a Document Check

To run a Document Check, you must create a check with the type set to document_check

Also, a valid clientId and documentId are required.

The provided document must have an issuingCountry and associated image attachments that adhere to our image specifications.

The front side of the document will always be required. For certain document types, you should also provide the back side.

If the back side is not provided, our engine will conduct the check based on the front side alone. It is highly recommended to provide both sides of documents for more robust checks to take place.

Result object

The result object is only returned when the status of the check is complete . It has two components - outcome and breakdown.

Outcome

The outcome attribute represents the overall check result. Returned values include:

1. clear: Indicates every analysis type conducted returned a successful result, and hence the document is authentic.

2. attention: Indicates at least one of the analysis results requires attention.

Breakdown
