How to integrate a payment system on Kwiga

On the Kwiga platform, you can integrate payment systems to configure student payment acceptance. This allows you to automatically receive payments from participants' cards, offer installment plans, and provide access via subscription.

To set up integration with a payment system, open your profile settings.

Click on your avatar in the top right corner of the platform and select All Settings. 

Next, go to the Integrations tab.

Then, open the Payment Systems section.

In the list of available services, find the required payment system and click on its name. A form will open, where you need to enter all the necessary connection parameters, such as an API key or a store ID, depending on the service's requirements.
After entering all the data, click Save, and the integration will be activated. Then, you can automatically receive student payments directly through Kwiga.

Recommendation:

Before enabling student payments, you should test the payment process yourself. To do this, create a test offer with a minimal price, such as 1 UAH or 1 USD.
Another option is to temporarily lower the price of a genuine offer, check the payment, and restore the original price after testing. Testing it in a different browser or incognito mode is recommended to ensure the payment check works correctly, as your expert account data may be stored in the current session.

Currently, integrations are available with many popular payment systems, and this list is constantly expanding.
If the required service is not on the list, contact us on Telegram - it may already be planned for addition or considered in a future update.
