Body parameters

string

default:"ARG"

required

ISO 3166-1 alpha-3 country code for this database service.Example: ARG

string

default:"arg_citizens"

required

Array containing this service ID. Pinning the service keeps the request scoped to this exact database.Example: arg_citizens

string

default:"John"

required

Given name to validate.Example: John

string

default:"Doe"

required

Family name to validate.Example: Doe

string

default:"1990-01-01"

required

Date of birth in YYYY-MM-DD format.Example: 1990-01-01

string

default:"1111111"

required

Document number extracted from or provided by the user.Example: 1111111

string

default:"user-1234"

Your stable user reference for this person, such as your internal user ID. Didit uses it to link standalone checks to the same end user and reduce duplicate-detection noise.Example: user-1234

Input rules & validation notes

Argentine DNI (7-8 digits)
document_number must contain digits only; remove spaces, hyphens, and punctuation before sending the request.
document_number must be 7-8 characters long.

How to call it

curl -X POST "https://verification.didit.me/v3/database-validation/" \
  -H "x-api-key: YOUR_API_KEY" \
  -F "issuing_state=ARG" \
  -F "services=arg_citizens" \
  -F "vendor_data=user-1234" \
  -F "first_name=John" \
  -F "last_name=Doe" \
  -F "date_of_birth=1990-01-01" \
  -F "document_number=1111111"

Every successful call returns HTTP 200. The outcome_code field tells you what actually happened — distinguishing, for example, a real biometric mismatch (BIOMETRIC_NO_MATCH) from a selfie that could not be read (BIOMETRIC_IMAGE_UNUSABLE). The status shown is the default feature status; your configured Partial Match / No Match actions can override it.

MATCH — The registry confirmed the identity and every checked field matched.

    }
  ]
}

PARTIAL_MATCH — The identification number was found but one or more personal fields (usually name or date of birth) did not fully match.

        "full_name": "no_match",
        "identification_number": "full_match"
      }
    }
  ]
}

NO_MATCH — The registry returned no match for the submitted data.

{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "ARG",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "arg_citizens",
      "service_name": "Argentina Citizens (AFIP)",
      "source_data": {
        "date_of_birth": "NO_MATCH",
        "full_name": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "date_of_birth": "no_match",
        "full_name": "no_match",
        "identification_number": "no_match"
      }
    }
  ]
}

Returned data

The exact fields surfaced in source_data depend on what the registry returns. The generated example for arg_citizens currently documents this normalized shape:

date_of_birth
first_name
full_name
identification_number
last_name
name_match_score

Pricing & SLAs

Argentina Citizens (AFIP) queries are billed only when Didit receives a conclusive result from the validation source.

Per-call price: $1.90 USD.
Billing: per successful query. You are not charged when the registry is unreachable, when required fields are missing, or when the request is rejected before reaching the source.
Latency: typical p95 < 2 s.
Availability: 99.9% per quarter on Didit’s side; downstream source availability varies by country and dataset.
