# Key features of ErynoaGroup

> Explore ErynoaGroup's core features: REST API, real-time webhooks, flexible authentication, integrations, and developer-friendly tooling.

ErynoaGroup is designed to give developers a fast, reliable foundation for building integrations. Here's a closer look at the features you'll use most.

## REST API

The ErynoaGroup REST API uses standard HTTP methods, returns JSON, and follows predictable URL conventions. Every endpoint is versioned under `/v1/` to ensure backward compatibility as the platform evolves.

**What you get:**

* Consistent request/response formats across all endpoints
* Detailed error messages with error codes and human-readable descriptions
* Full support for filtering, sorting, and pagination on list endpoints
* HTTPS-only communication for all requests

## Real-time webhooks

Rather than polling the API for changes, configure webhooks to receive push notifications when events happen in ErynoaGroup. Webhooks are delivered as HTTP POST requests with a JSON body.

**Webhook features:**

* Subscribe to specific event types (e.g., `resource.created`, `resource.updated`)
* Automatic retry with exponential backoff on delivery failure
* Signature verification using HMAC-SHA256 to confirm authenticity
* Delivery logs and re-delivery from your dashboard

## Authentication

ErynoaGroup uses API key authentication — simple, secure, and easy to integrate.

    Generate scoped keys from your dashboard. Rotate or revoke them any time without affecting other keys.

    Limit each key to read-only or read-write access to follow the principle of least privilege.

## Sandbox environment

Test your integration safely in the ErynoaGroup sandbox environment. The sandbox mirrors production behavior but uses isolated data that never affects live operations.

<Tip>
  Always develop and test against the sandbox before switching to production keys.
</Tip>

## Dashboard

The ErynoaGroup dashboard gives you a visual interface for managing your integration without writing code:

* Create and manage API keys
* Monitor API usage and error rates
* Configure and test webhooks
* View event logs and re-deliver failed webhook payloads

## Rate limiting and reliability

ErynoaGroup enforces per-account rate limits to ensure fair usage and platform stability. Production plans offer higher limits than sandbox. If you need increased limits, contact support.
