# Particle / CHORDS Integrations

Particle IoT Cloud Webhooks are a powerful feature that enables seamless integration between Particle devices and external services, such as CHORDS (Cloud-Hosted Realtime Data Services for the Geosciences). Here's an overview of what they are and how they facilitate data transfer:

### **What Are Particle Webhooks?**

Webhooks are a mechanism for sending data from Particle devices to external web services. They act as a bridge between the physical world (data collected by Particle devices) and the digital world (cloud-based services). When a Particle device publishes an event, the webhook listens for that event and triggers an HTTP request to a specified URL. This request can include data from the event, formatted according to your needs, and can also receive responses back from the external service.
