Mercury Webhooks API

Subscribes a partner application to event notifications such as transaction created/updated, payment status change, and account balance threshold events. Mercury signs each delivery so receivers can verify authenticity.

Mercury Webhooks API is one of 16 APIs that Mercury publishes on the APIs.io network, described by an AsyncAPI event-driven specification.

Tagged areas include Webhook, Event, and Notification. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

This event API exposes 1 operation across 1 channel, and defines 10 schemas. It is described by AsyncAPI 2.6.0, at version 1.0.0.

The API connects through a single server, {webhookUrl} (https).

Where this information came from

This is an independent, third-party profile of Mercury Webhooks API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
