## Onboarding Process

### `Public Partner`

No need to apply. You could use `public` as partner ID to access to FaTPay service.

### `Basic Partner`

If the customization is a must feature for your business, such as adding new issued cryptocurrency. Please leave a message at <operations@fatpay.xyz> and apply the  Basic Partner account.

* `APIPublicKey`: Generated by the partner and submitted to FaTPay for API request validation;
* `SecretKey`: Provided by FaTPay for computing the [signature](/reference/integration-tutorial/widget-signature.md) of widget URL;

<summary>Generating <code>APIPrivateKey</code>/<code>APIPublicKey</code> key pair</summary>

There are many ways to generate ***RSA public and private(2048 bits) key pairs in PKCS#8 format***.

Here we just provide an example for MacOS/Linux users via [OpenSSL](https://www.openssl.org/).

{% code overflow="wrap" %}

```shell
# generate private key in PKCS#8 formati
openssl genpkey -out APIPrivateKey.pem -algorithm RSA -pkeyopt rsa_keygen_bits:2048

# extract public key from private key
openssl rsa -pubout -in APIPrivateKey.pem -out APIPublicKey.pem
```

{% endcode %}

</details>

{% hint style="warning" %}
Please make sure you **NEVER** disclose the ***`APIPrivateKey`*** and ***`SecretKey`***.
{% endhint %}
