Create a transaction

Create a transaction

Creates a transaction for the catalog prices or one-off items you pass and returns it with a checkout URL for collecting payment.

List items by price ID and quantity. An automatically collected transaction (the default) is paid at checkout.url, your default payment link plus ?_ptxn= and the transaction ID. Adding customer_id and address_id makes it ready, and completing it creates the related subscription. On the MCP server, find the method with search and run it with execute; a live OAuth connection needs write access first.
