I keep getting the “Payment initialization failed: the id field specified is not a site integration” error. Below are the steps I went through:
- Install wordpress, woocommerce and paynow plugin
- Create a new integration in my Paynow account
- Set WooCommerce currency to USD
- Create a product
- Add USD Integration ID and Key in WooCommerce payment settings for Paynow
- Try to checkout on the product page, then error comes up.
