GET/api/v1/kyc/nin

Retrieve the identity record tied to a Nigerian National Identity Number (NIN) from NIMC.

Headers

Header	Required	Description
`Authorization`	Yes	Your app’s secret key, sent as-is — not `Bearer`.
`AppId`	Yes	The App ID from your dashboard.

Query parameters

Parameter	Type	Required	Description
`nin`	string	Yes	A valid 11-digit National Identity Number.

Response

Returns an entity with the holder’s name, gender, date of birth, phone number, and a base64-encoded photo.

Other NIN lookups

This endpoint is the basic tier. Two richer tiers return more of the NIMC record, and each is documented on its own page:

Tier	Endpoint	What it adds
Basic	`GET /api/v1/kyc/nin`	Names, gender, date of birth, phone number, photo.
Advanced	`GET /api/v1/kyc/nin/advance`	Birth details, full residence and origin, and next of kin.
Premium	`GET /api/v1/kyc/nin/premium`	Everything in Advanced, plus demographics, profession, previous name and address, height, title, and signature.

Advanced and Premium can both return the holder’s tax details (tax_id and tax_residency) when you add nin_tin=true to the query. Each tier is billed separately — pick the smallest one that covers your use case. There is also NIN Slip (GET /api/v1/kyc/nin/nin_slip), which returns the person’s NIN slip data.

Errors

Code	Meaning
`400`	Bad request — a required parameter is missing or malformed.
`401`	Unauthorized — check your key and `AppId` (no `Bearer` prefix).
`402`	Insufficient wallet balance. Fund your wallet.
`404`	No record found for the supplied identifier.
`424`	The upstream source was unavailable — retry shortly.
`429`	Too many requests — back off and retry.
