# Payment Service Provider

Saaster makes use of the payment service provider [Payrexx](https://www.payrexx.com/?ref=paweco). At the moment, integration of other payment provides is not planned.

Payrexx is a [Swiss Payment Service Provider](https://www.payrexx.com/?ref=paweco) and is subject to Swiss quality control. And anyone who knows Switzerland knows how important that is.

But this is not the only reason why we decided to work with [Payrexx](https://www.payrexx.com/?ref=paweco). Another reason is that [Payrexx ](https://www.payrexx.com/?ref=paweco)has already integrated tons of other payment service providers in the system, so that every SaaS provider can probably find their desired PSP in it.

The following chapters will guide you through the configuration and integration of Payrexx in saaster.

## Create an account

First you need an account with Payrexx. [Click here to register](https://www.payrexx.com/?ref=paweco).\
Enter your company name or a part of it here:

After you have created your login, you will find yourself in the [Payrexx ](https://www.payrexx.com/?ref=paweco)account.

## Create an API key

Now you need to create an API key. To do this, navigate to **API & Plugins** on the left-hand side.

Click the button "Add API Key" and assign a meaningful name to the new key. It is best to choose the name of your project:

<figure><img src="/files/NBmhYrVG1os5E0ViBpMP" alt=""><figcaption></figcaption></figure>

Keep the API key you received safe. You will need this key in the further steps.

## Create a webhook

Now you create a webhook. This is used to store payment methods and to charge them repeatedly later. To do this, navigate to **Webhooks** on the left-hand side.

<figure><img src="/files/hj9cHlXzwPlGOo4wt6qZ" alt=""><figcaption></figcaption></figure>

You need two webhooks, one for the *development environment* and one for the *production environment*.

### Development environment

You will find a file called "payrexx\_webhook\_dev.cfm" in the saaster file structure in the "frontend" folder. You must now upload this file to any server that can be reached from the internet.&#x20;

*Example:*

`https://your-domain.com/frontend/core/handler/payrexx_webhook_dev.cfm`

This is also the path that you must enter as the webhook.\
Click "Add webhook". Give the webhook a unique name and write the path to the file you just uploaded in the field:

<figure><img src="/files/usU7mxkPuTjyyTJNrwpI" alt=""><figcaption></figcaption></figure>

Configure your webhook exactly as shown above.

### **Production environment**

For the productive environment you can add a webhook and specify the file "payrexx\_webhook.cfm" also in the folder "frontend". Everything else remains the same.

**Note: You must add a password defined in a url variable:**\
`https://your-domain.com/frontend/core/handler/payrexx_webhook.cfm?pass=xxx`

The password is defined in config.cfm

## Create a payment page design

To ensure that your payment page matches your design, you can create a corresponding design in [Payrexx](https://www.payrexx.com/?ref=paweco).

Click on "Settings" on the left, then on "Look & Feel":

<figure><img src="/files/KUfDZ8jE8ojo6yXLFjYD" alt=""><figcaption></figcaption></figure>

Click the green button "Add a new profile" at the top right and fill this form according to your wishes:

<figure><img src="/files/sfShKxx7skncewU86PfH" alt=""><figcaption></figcaption></figure>

Save the new profile at the bottom. You will now get a unique ID for your design.&#x20;

<figure><img src="/files/PmPyM9bRPckX0JWXQ6vq" alt=""><figcaption></figcaption></figure>

Please copy this ID into the config.cfm of your project. Read more about the configuration / config.cfm here:

[Installation](/getting-started/installation.md)
{% endcontent-ref %}

## Payment providers

In this menu you can configure your payment methods and choose the payment provider.

Please follow the instructions from [Payrexx](https://www.payrexx.com/?ref=paweco), as this configuration can be very extensive. You will also have to provide [Payrexx ](https://www.payrexx.com/?ref=paweco)with some confirmations in order to activate certain payment methods.
