Pay Invoice Through a Specific Payment System sale.paysystem.pay.invoice

If you are developing integrations for Bitrix24 using AI tools (Codex, Claude Code, Cursor), connect to the MCP server so that the assistant can utilize the official REST documentation.

Scope: pay_system

Who can execute the method: a user with permissions to create and edit CRM invoices (legacy version)

This method is used to pay an invoice (legacy version) through a specific payment system. It is called after processing the response from the payment system.

Method Parameters

Required parameters are marked with *

Name `type`	Description
INVOICE_ID* `integer`	Identifier of the legacy invoice. The service crm.invoice.* is used to retrieve invoice information.
PAY_SYSTEM_ID `sale_paysystem.ID`	Identifier of the payment system
BX_REST_HANDLER `string`	Symbolic identifier of the REST handler for the payment system. You must provide either the `PAY_SYSTEM_ID` parameter or the `BX_REST_HANDLER`: When providing `PAY_SYSTEM_ID`, the payment system with the specified identifier is used. When providing `BX_REST_HANDLER`, the first found payment system with the specified handler is used. If both parameters are provided, the `PAY_SYSTEM_ID` parameter takes precedence.
