# Handshake

## Handshake - Get your MTLS CERT\&KEY

<mark style="color:green;">`POST`</mark> `/handshake`

To access and utilize the full functionality of our API, you must obtain an MTLS (Mutual TLS) Certificate and key for secure authentication.

**Important:** All API functions, except for **Handshake** and **Subscription**, mandate MTLS authentication. Without this authentication, access to these functions will be restricted.

Ensure your MTLS credentials are properly configured before proceeding with the API integration.

**Headers**

| Name         | Value              |
| ------------ | ------------------ |
| Content-Type | `application/json` |

**Body**

| Name     | Type   | Description |
| -------- | ------ | ----------- |
| `apikey` | string | apikey      |
