This is a connect application to integrate PayPal payment methods and package tracking into Commercetools. It follows the folder structure to ensure certification & deployment from commercetools connect team as stated here.

PayPal commercetools connector is available in the commercetools marketplace.

The payments demo can be seen at https://poc-mediaopt2.frontend.site/.

Latest release notes

The latest version of the connector in commercetools Merchant Center is not publicly available due to vulnerability in commercetools mc-scripts package. Access cen be provided on request.

Integration

The connector is supposed to be used together with the PayPal client app. The client is available at npm and github. The connector is responsible for the backend integration with commercetools and PayPal, while the client is responsible for the frontend. If for some reasons the PayPal client app can't be used, the PayPal JS SDK should be used instead. The example of the integration with commercetools frontend is covered in docs/usecases/README.md and the code can be seen in github.
