# OneSignal API Documentation

This is the complete API documentation for connecting to the OneSignal API using MindCloud's Universal API.

MindCloud offers one normalized API to access 3,400+ apps from a single place. It centralizes authentication and normalizes app APIs so they are easier and more consistent to use.

## Quickstart

1. A **MindCloud account** — sign in or create an account at [MindCloud](https://app.mindcloud.co).
2. A **MindCloud API Key** — create one in [API Keys](https://app.mindcloud.co/user/api-keys). Keep it on your server.
3. At least one **OneSignal connection** — create or choose one in [Connections](https://app.mindcloud.co/credentials). Note its `connectionId`.
