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.

Note: Adding customer_id and address_id makes it ready, and completing it creates the related subscription. Over MCP, a live OAuth connection needs write access first.

Set up

Use the first option your agent supports.

MCP (official, remote)

Add this server to your agent's MCP settings, then sign in when asked.

{ "mcpServers": { "paddle": { "url": "https://mcp.paddle.com/mcp" } } }

Call the MCP tool execute with POST /transactions.

Server URL: https://mcp.paddle.com/mcp

API (official)

• Base URL: https://api.paddle.com
• Endpoint: POST /transactions
• Auth: send the header Authorization: Bearer $PADDLE_API_KEY
• Get a key: https://vendors.paddle.com/authentication-v2
• Docs: https://developer.paddle.com/api-reference/about

Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.

Rules

• Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
• Never print API keys.
