Submitting Captured Data

After you receive a response from the /start endpoint, the next step is to submit captured data to another endpoint. Captured data might be in the form of a barcode, a front image, or a back image from the identification document. You must submit different types of captured data based on the combination of document_type and signals in the /start request.

For example, suppose you submitted na_dl as the document_type along with idcheck in the signals array. This is a common combination used to verify the barcode of a North American driver license. The /start endpoint returns a transaction_id value. You could next use the /submit-barcode endpoint to submit transaction_id along with barcode, which is a base64-encoded string of the barcode data from the backside of the driver license.

Our Direct customers must capture and encode the document images separately.

The following table shows the capture data requirements for common document_type and signals combinations.
