# Getting started

To use our Pay Widget, you must register in our merchant dashboard using the following links:

{% hint style="info" %}
We recommend to start with the Sandbox environment first
{% endhint %}

| Environment | URL                                          |
| ----------- | -------------------------------------------- |
| Sandbox     | <https://sandbox-dashboard.fonbnk.com/login> |
| Production  | <https://dashboard.fonbnk.com/>              |

After registration, go to the Navigation -> API Settings. There you find 2 values that are required for the integration:

* <mark style="color:yellow;">**Source param**</mark>
* <mark style="color:yellow;">**URL signature secret**</mark>

Then go to the Navigation -> Webhooks -> Settings and set a URL you want to receive webhooks to.

{% hint style="info" %}
You can use the URL from <https://webhook.site/> at the first stage, just to see how it works
{% endhint %}

With the parameters and webhook set up, you're ready to configure the Pay Widget for your needs.
