Verifies input data against the Election Commission of India database. Didit exposes this service through POST /v3/database-validation/ so you can verify the submitted data against the authoritative source and receive normalized match results.

`epic_card`	Yes	`ABC1234567`

Price: $0.15 per successful query

In a workflow, epic_card is not printed on an identity document, so no step produces it on its own. Collect it from a Questionnaire answer, a Document AI extraction field, or a value you send when you create the session, and map it on the Database Validation step. Until it is mapped the workflow editor shows this service disabled and names the missing input; at run time a missing input means the check is skipped before any query, so you are never billed for a database that could not be asked. Not every document this service accepts carries the identifier it queries by. When the identifier is not extracted from the document the check is recorded as not applicable - no database is queried and you are not charged - which for some countries is a large share of real users. To cover them, also collect the identifier from a Questionnaire answer, a Document AI extraction field, or a value you send when you create the session, and map it on the Database Validation step.

Body parameters

string

default:"IND"

required

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

string

default:"ind_epic_voter_s_registration"

required

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

Explicit end-user consent for this service.Example: true

string

default:"John Doe"

required

Full legal name to validate.Example: John Doe

string

default:"1990-01-01"

required

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

string

default:"ABC1234567"

required

EPIC voter card number.Example: ABC1234567

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

epic_card must match [A-Za-z]{3}\d{7,14}.

How to call it

curl -X POST "https://verification.didit.me/v3/database-validation/" \
  -H "x-api-key: YOUR_API_KEY" \
  -F "issuing_state=IND" \
  -F "services=ind_epic_voter_s_registration" \
  -F "vendor_data=user-1234" \
  -F "consent=true" \
  -F "full_name=John Doe" \
  -F "date_of_birth=1990-01-01" \
  -F "epic_card=ABC1234567"

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": "IND",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "ind_epic_voter_s_registration",
      "service_name": "India EPIC (Voter's Registration) (ECI)",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "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": "IND",
  "match_type": "partial_match",
  "validations": [
    {

      "source_data": {
        "date_of_birth": "1990-01-01",
        "full_name": "John Doe",
        "identification_number": "SAMPLE-ID-12345"
      },
      "validation": {
        "date_of_birth": "full_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": "IND",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "ind_epic_voter_s_registration",
      "service_name": "India EPIC (Voter's Registration) (ECI)",
      "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 ind_epic_voter_s_registration currently documents this normalized shape:
