Body parameters

string

default:"SLV"

required

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

string

default:"slv_dui"

required

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

string

default:"111111111"

required

Document number extracted from or provided by the user.Example: 111111111

string

default:"1990-01-01"

required

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

string

default:"John"

Given name to validate.Example: John

string

default:"Doe"

Family name to validate.Example: Doe

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

Salvadoran DUI (exactly 9 digits)
document_number must contain digits only; remove spaces, hyphens, and punctuation before sending the request.
document_number must be exactly 9 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=SLV" \
  -F "services=slv_dui" \
  -F "vendor_data=user-1234" \
  -F "document_number=111111111" \
  -F "date_of_birth=1990-01-01"

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.

{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "SLV",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "slv_dui",
      "service_name": "El Salvador - DUI verification",
      "source_data": {
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345"
      },
      "validation": {
        "date_of_birth": "full_match",
        "identification_number": "full_match"
      }
    }
  ]
}

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

{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "SLV",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "slv_dui",
      "service_name": "El Salvador - DUI verification",
      "source_data": {
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345"
      },
      "validation": {
        "date_of_birth": "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": "SLV",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "slv_dui",
      "service_name": "El Salvador - DUI verification",
      "source_data": {
        "date_of_birth": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "date_of_birth": "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 slv_dui currently documents this normalized shape:

full_name
identification_number
