Spain

eKYB Prefill in Spain leverages Spain's source of truth to automatically retrieve and populate business information based on a company's CIF or VAT number, including the business name, registered address, entity type, registration status, directors, shareholders, and additional financial and corporate data, without requiring manual input from the user.

Source

Direct API approach

For general integration notes and shared response semantics, see the eKYB Prefill API Reference.

All module configurations and user data can be forwarded directly in the request for performing a Prefill lookup. This overrides existing configuration and data collected about the user.

Endpoint

POST /omni/externalVerification/ekyb-prefill

Request parameters

Tax ID formats

The taxId field accepts three CIF formats and a VAT number format. Routing between them is determined automatically by the format of the submitted value.

Inputs that do not match any of the above formats return a 400 error.
