Fine-grained subscriptions

Enable your users to subscribe to your events by setting up a webhook. They can choose which event types they want to receive.

Multi subscriptions

Your users can register several webhooks, we will send events to all of them!

Event scoping

Scope events to one or several levels of your application. Users, organizations, administrators, [insert your own], they can all handle subscriptions to their events.


Either use Hook0 out-of-the-box dashboards to let your users see events that went through their subscriptions, or build your own with the API.

Failure notification

If after several retries we still can't successfuly reach a webhook, your subscriber is notified by email.

Events & responses persistence

Hook0 can keep track of every event your application sent it and of every webhook call. This can helps you debug things or act as an audit log !

High availability

Hook0 won't miss the events you send it.

GDPR Compliant

Hook0 is fully GDPR compliant and can easily execute a data processor agreement with your company if needed.

Data Security

Hook0 utilizes best practices for data storage and encryption. We also offer single-tenant and on-premise deployment options.

Hook0 robust architecture automatically scales to handle thousands of requests per minute.

Give it enough time and open-Source always wins in the end!

Use Cases

When something happens on your system, let your users know immediately!

No Code Solutions

Integrate with platforms like Zapier and Integromat and offer your users webhooks without any code.

Stop Polling

We all know polling for data is inefficient. Use Webhooks instead to push data to your users.

No More Custom Reporting

Have your users subscribe to your webhooks and give them a self serve integration.

Asynchronous Notifications

For time consuming tasks, use webhooks to asynchronously notify your users when they are done.

Internal Systems Communication

An event bus solution can be heavy, start with internal webhooks to communicate between internal services.

Platform Notifications

Giving your platform users access to events occuring on your platform improves the experience for everyone.

Back Office Operations

Let your subscribers know an order has been refunded or shipment has been delivered so they can take action.

Provide Updates On Progress

As data in your system changes, update your subscribers with those changes.

Frequently asked questions

Can’t find the answer you’re looking for?
Reach out to our customer support team.

What are Webhooks as a Service?
We take everything that goes into a webhook service (retries, backoffs, endpoint monitoring, subscriber management, etc) and package it up into a platform that you can easily integrate with using our API.
How long does it take to integrate with Hook0?
Every setup is different, but a senior developer should be able to build out a working version within a day and be live in under a week.
How is this different than Zapier or Integromat?
Zapier is an automation tool that helps connect services together. Hook0 is a platform that gives your application the ability to send webhook events to your users.
We've already built webhooks, can we still use Hook0?
That is a great use case for using Hook0 since you've already validated that your users want webhooks. There is a good chance that what Hook0 offers is much more robust than your solution. If that is the case, then migrating your custom solution to Hook0 will allow you to focus on other priorities while offering a top notch webhook solution.
