v0.4.0 of our @n8n_io node supports 817 webhook source types, up from 151.

When the platform signs its webhooks, Hookdeck checks the signature before the event reaches your workflow.

📹 Webhooks by Example #4, with Michael McGovern from @PaddleHQ.

A subscriber is only present at checkout. After that, every change arrives as a subscription.updated webhook, and its status decides whether the customer can still use your product.

📹 An email, delivered to ChatGPT as an MCP event.

Resend doesn't support MCP Events. The open-source MCP Events bridge, built on Hookdeck Event Gateway, turns its webhooks, or any other service's, into MCP events.

📹 Webhooks by Example, Episode 3

Kevin Lewis from @apify walks through Apify webhooks for long-running runs: run events, a payload that points to the run's dataset, and ad hoc callbacks per run for apps and agents.

Kevin's case for the webhook: some Actor runs take tens of minutes, and "sometimes waiting for it... synchronously is not always the best shout."

Start the run, respond straight away, fetch the dataset when the webhook arrives.

Not every webhook is JSON.

Hookdeck Event Gateway now delivers audio, images, PDFs, archives, protobuf and multipart uploads byte for byte.

Transformations run Node.js too, so you can gunzip a batch, parse a PDF, or turn a JSON event into a PNG.

@leggetter shows us how 🧵

It works the other way too. Return a Buffer, set content-type, and the destination gets a file.

Our demo turns JSON events into a PNG receipt, a WAV chime, a PDF invoice and an SVG chart. Uses Node built-ins, not npm packages.

What is MCP Events? A draft MCP extension (SEP-3415) that lets an event wake your AI agent, instead of it waiting for a prompt.

Here's how it works ↓

To try it now, we built the MCP Events bridge: an open-source MCP server that turns webhooks from GitHub, Resend or any service that sends them into MCP events. It runs on Hookdeck Event Gateway.
