# Store a payment data map

Validates and stores rules for mapping a complete payment object: payment and party fields, document connections, reviewed value translations, sender handling, and amount resolution. Download or copy the definition from [Smart Payload Mapping](/payment-api/tools/payload-mapper-v2), then submit it as definition alongside a name. Access is determined by your credentials.

Storage validates the schema version, safe paths, known targets, unique field sources and targets, compatible array associations, document connection rules, and allowed translation outputs. Value rules must match a configured field or document-type connection and must not redefine an existing Axiym code. Invalid or conflicting rules are rejected with HTTP 422. Actual source data, document matches, and corridor requirements are validated when the map is used.

New maps have status ACTIVE. The response includes paymentDataMapId and contentHash. Definitions are immutable: store changed rules as a new map and use its new identifier.
