Integrate APIs

There is WordPress with a store.

Task:
- API integration so that we can sell ICP products- Product setup and integration can be done on the product page- The ordered key must be sent by email to the customer- The key must be registered and stored so that we can print a CSV with product key information (attachment will be given on request)- Security must be ensured so that no key will be sent without payment- Api must be integrated as a plugin- Keep the code clean and fresh
