The Electrum Regulated Payments API is an asynchronous API that allows partners to participate in various nationally regulated payment schemes.

This document describes the operations exposed by Electrum for partners to consume in order to initiate outbound or respond to inbound payments.

As the Regulated Payments API is asynchronous, partners have a choice of how to integrate with Electrum:

• Webhooks: Electrum will send events to the partner containing inbound payments to action, or responses to outbound payment requests. Webhooks are defined in this document.
• Partner API: Electrum will call operations exposed by the partner containing inbound payments to action, or responses to outbound payment requests. The operations are defined in the Electrum Regulated Payments Partner API.

Receiving transactional events via webhooks or API are equivalent, except that it may be more familiar or convenient to implement one style or the other. Partners may request the method of communication Electrum should use when selecting which payment schemes to participate in.
