### <mark style="color:red;">**Preliminary Works**</mark>

The following information is requested from the provider for the brand-specific and production (live) environment.

* **API\_URL**
* **API\_KEY**

A secret\_key is generated with a minimum length of 41 characters. The generated key must be kept throughout the installation. An example command line to generate a random key:

```
openssl rand -base64 41
```

A hash\_key must also be generated with a minimum length of 32 characters. The generated key must be kept throughout the installation.

### <mark style="color:red;">**Environment Variables**</mark>

The extension installed to the relevant project in ACC must have the following environment variables. Environment variables can be entered before or after the deployment phase. As changes are made to the environment variables, the deployment process must be performed again.

## <mark style="color:red;">**Omnitron Settings**</mark>

The installed extension must also be defined to the project via Omnitron. This can be done on the **Payment Options & Add/Edit POS Integration** pages. After the settings are completed, it will be accessible under a new tab on the payment screen as it is a redirection type payment integration.

### <mark style="color:red;">**Payment Options**</mark>

One payment option must be defined in Omnitron to be specific for the extension installed. Explanations on how the settings should be made at this stage are in the table below.

| Field               | Description            |
| ------------------- | ---------------------- |
| Payment Option      | Redirect to bank       |
| Payment Option Name | Mollie                 |
| Payment Option Slug | mollie                 |
