# Webhooks

Webhooks allow you to automate workflows and receive real-time updates from res:harmonics. Instead of constantly polling for changes, webhooks enable the service to send data directly to your system whenever specific events occur. This makes integrations more efficient and responsive.

## Key Principles for Using Webhooks

### Understand the Basics

A webhook is essentially an automated notification sent to a URL you provide. When an event occurs (e.g., a payment is processed, a booking is updated), res:harmonics sends an HTTP POST request to your endpoint with event details in the payload.

### Set Up Your Endpoint

- Create a publicly accessible URL in your system to receive webhook requests.
- Design your endpoint to handle incoming JSON payloads and respond with a 200 OK status to confirm successful receipt.
- Log incoming requests for debugging and verification.


### Secure Your Integration

- HTTPS Only: Always use secure connections to protect data in transit.
- Restrict Access: Limit the endpoint to only accept traffic from res:harmonics’ IPs, if possible.
- Create a secret that is included in the header message, you can set the secret in res:harmonics, it will be included in the POST message header ‘x-auth-token’


### Filter and Process Events

- Identify which events are relevant to your workflow and configure the webhook accordingly.
- Validate the payload format and required fields to ensure the data is actionable.
- Use the event data to trigger automated actions, update systems, or notify users.


### Plan for Failures

- Implement retry logic for your webhook endpoint to handle transient error
- Monitor webhook delivery logs provided by res:harmonics for any missed or failed events.
- Use queuing systems (e.g., RabbitMQ, AWS SQS) for asynchronous processing to avoid bottlenecks.


### Test and Debug

- Test webhooks using tools like Postman, Webhook.site, or a test mode provided by res:harmonics.
- Log every request and response to help diagnose issues and refine your integration.


## Why Webhooks Matter to You

Webhooks make your integrations more:

- Efficient: Receive updates instantly without polling.
- Customizable: Tailor the data flow to your needs by selecting specific events and processing logic.
- Reliable: Focus on real-time automation, ensuring your systems stay in sync


## Getting Started

- Review the res:harmonics Documentation: Understand the available events and payload structure.
- Design Your Workflow: Map out what should happen when an event triggers.
- Monitor and Optimize: Continuously improve your endpoint’s performance and reliability.


With webhooks from res:harmonics, you can create powerful, automated workflows that enhance productivity and streamline your systems. They enable you to get the most out of your integration with minimal overhead.
