Document Types and Signals

The following table shows document_type values and associated signals for the /start endpoint request body.

`document_type` Value	Associated `signals` Value	Description
`na_dl`	`idcheck`	Select `na_dl` if you want to validate a North American driver license. It is the default value if no value is provided. If you select `na_dl`, then include `idcheck` at a minimum in the `signals` array.
`other`	`ocr_scan`	Select `other` if you want to validate a passport card, travel document, or other international document. If you select `other`, then include `ocr_scan` at a minimum in the signals array.
`passport`	`ocr_scan`	Select `passport` if you want to validate a passport booklet. If you select `passport`, then include `ocr_scan` at a minimum in the `signals` array.

In the table above, the Associatedsignals Value column includes the minimally suggested signals array value for eachdocument_type. For example, the first row shows na_dl as the document_type and idcheck as the associated signal. This means, at minimum, if you select na_dl as the document_type, then you should include idcheck in the signals array. The private_data request object might look like this:

{  
  "private_data": {  
    "document_type": "na_dl", 
    "signals": [
      "idcheck"  
    ]  
  }  
}
