Create payment method

POST https://api.invunion.com/api/v1/payment-methods payment_methods:write Markdown

Create a catalog payment method.

Creates a catalog instrument. name is required, and either iban or identifier is required. If code is omitted, Invunion assigns the next PM-NNN code. counterparty_id must already exist; this endpoint does not create a counterparty. To create a counterparty and a catalog instrument in one request, use POST /counterparties with payment_method. An IBAN or identifier that already belongs to another catalog instrument returns 409.
