Business Management

Create business (idempotent)

Create a new business with idempotency support via external_id.

Supported Markets: EU/UK, Nordic, and APAC countries (GB, DE, FR, NL, ES, BE, IT, IE, AT, PT, SE, NO, DK, FI, IS, MY, SG)

Entity Type Validation:

GB, DE, NL, ES, BE, MY, SG: Must use country-specific entity types (see documentation)
All other countries: Any entity type string is accepted

Idempotency: If a business with the same external_id already exists for your partner, this endpoint will return the existing business (HTTP 200) instead of creating a duplicate.

Response Metadata: Includes _meta field indicating creation vs idempotent return.

Required Fields: external_id, legal_name, entity_type, email
