Workflow & Automation

Webhooks

Webhooks are mechanisms that allow one application to send real-time data to another whenever an event occurs. In Activepieces, webhooks are supported as both triggers and actions, enabling real-time data exchange between services and making workflows faster and more responsive.

What Are Webhooks?

Webhooks are automated messages sent from one app to another when something happens. They are sometimes described as “reverse APIs” because instead of a system needing to constantly request information, a webhook pushes data immediately when an event occurs.

The idea comes from the need for efficiency in application communication. Rather than polling an API repeatedly for updates, webhooks provide instant notifications.

For example, when a payment is processed, a webhook can notify an accounting system instantly instead of waiting for a scheduled sync.

In Activepieces, webhooks can serve as triggers (starting a flow when a webhook is received) or actions (sending a webhook from a flow to another system). This flexibility makes them essential for real-time automation.

How Do Webhooks Work?

Webhooks work through simple HTTP requests. When a specific event occurs in an application, it sends an HTTP POST request to a predefined URL with the relevant data. In Activepieces, the process typically looks like:

  • Trigger setup: A webhook URL is generated in Activepieces. This URL is shared with the source app that will send data when an event occurs.
  • Event occurs: When the event happens, such as a form submission or payment confirmation, the app sends data to the webhook URL.
  • Flow initiation: Activepieces receives the data and starts the flow using the webhook as the trigger.
  • Action setup: Flows can also send data out via webhook actions, posting data to external endpoints.
  • Data exchange: Information is transferred instantly between systems, ensuring real-time automation.

This lightweight communication method makes sure workflows are responsive and efficient.

Why Are Webhooks Important?

Webhooks are important because they make data exchange immediate and reliable. In a world where real-time responses are expected, webhooks provide a way to connect systems without delays.

The main reasons webhooks matter include:

  • Real-time automation: Eliminates delays by triggering workflows the moment events occur.
  • Efficiency: Reduces the need for constant API polling, saving resources.
  • Flexibility: Can connect virtually any system that supports webhooks.
  • Scalability: Handles high volumes of events with minimal overhead.
  • Integration: Acts as a universal connector when no direct integration exists.

For Activepieces, webhooks are foundational. They allow users to connect apps that aren’t in the pre-built library, expand integrations, and design workflows that run instantly.

Common Use Cases

Webhooks are versatile and can be applied in many scenarios. Examples in Activepieces include:

  • Customer support: Start a flow when a new support ticket is submitted through a third-party form.
  • Sales enablement: Trigger workflows when a new lead signs up via a landing page tool.
  • Marketing: Send webhook data from ad platforms to Activepieces to kick off campaign workflows.
  • Finance: Notify accounting systems instantly when a payment or invoice is completed.
  • Operations: Connect IoT devices that send webhook events into workflows for monitoring or automation.
  • AI workflows: Feed webhook data directly into AI steps for real-time analysis or response generation.

These examples highlight how webhooks provide real-time connectivity across diverse applications.

FAQs About Webhooks

What are webhooks in automation?

Webhooks are automated messages sent between systems when an event occurs. They allow real-time data exchange by pushing information instantly to another app or workflow.

How are webhooks different from APIs?

APIs typically require one system to request information from another at intervals. Webhooks, by contrast, push data immediately when an event happens, making them faster and more efficient for real-time automation.

How does Activepieces support webhooks?

Activepieces supports webhooks as both triggers and actions. Users can start flows when data is received from a webhook or send data out to other systems, enabling real-time communication between apps and workflows.
