Verify a customer’s Nigerian international passport by uploading a photo of the data page — no manual passport number entry required. We read the details and compare the face on the document with a selfie. No liveness check is needed. See Supported countries for every country you can verify passports from.

Passport is single-sided — only document_front is needed.

selfie_image is required — the face extracted from the document is compared against it. This is a still-image comparison (not liveness).

Endpoint

POST /api/onboarding/document_verification/nigeria/passport

Request

Headers

Header	Value	Required
`x-access-token`	Your API secret key	Yes
`Content-Type`	`multipart/form-data`	Yes

Body Parameters

Parameter	Type	Required	Description
`document_front`	file	Yes	Photo of the passport data page. JPG, PNG or single-page PDF, max 10MB
`selfie_image`	file	Yes	A selfie to compare against the document’s face photo. JPG or PNG, max 5MB

document_type and country are not needed — this endpoint is already scoped to Nigerian passports.

A scanned document can be uploaded as a single-page PDF, for example -F "document_front=@/path/to/scan.pdf".

Example

curl -X POST "https://adhere-api.smartcomply.com/api/onboarding/document_verification/nigeria/passport" \
  -H "x-access-token: YOUR_SECRET_KEY" \
  -F "document_front=@/path/to/passport.jpg" \
  -F "selfie_image=@/path/to/selfie.jpg"

const formData = new FormData();
formData.append("document_front", fs.createReadStream("/path/to/passport.jpg"));
formData.append("selfie_image", fs.createReadStream("/path/to/selfie.jpg"));

const response = await fetch(
  "https://adhere-api.smartcomply.com/api/onboarding/document_verification/nigeria/passport",
  {
    method: "POST",
    headers: { "x-access-token": "YOUR_SECRET_KEY" },
    body: formData,
  }
);
const data = await response.json();

import requests

response = requests.post(
    "https://adhere-api.smartcomply.com/api/onboarding/document_verification/nigeria/passport",
    headers={"x-access-token": "YOUR_SECRET_KEY"},
    files={
        "document_front": open("/path/to/passport.jpg", "rb"),
        "selfie_image": open("/path/to/selfie.jpg", "rb"),
    },
)
data = response.json()

Face Match Notes — if the comparison service itself fails, attempted reflects whether a comparison was actually run and verified comes back null with a reason field explaining why — this is different from verified: false, which means the comparison ran and the faces didn’t match. A face-match problem never blocks the underlying document data — the rest of data is still returned.
