Body
multipart/form-data
The kind of document being submitted. Which values are valid depends on country — passport works for every supported country; the rest are country-specific.
Available options:
national_id, passport, drivers_license, voters_card, kenya_id, cac_certificate, utility_bill Example:
"passport"
Country the document was issued in.
Available options:
nigeria, kenya, ghana, canada, usa, cote d'ivoire Example:
"nigeria"
Front of the document. JPG or PNG, max 5MB.
Back of the document. Optional for every type, but recommended for two-sided documents (national_id, kenya_id, drivers_license) — extraction may be less complete without it.
Response
