After successfully getting the billing key, the billing key is stored on the i'mport server mapped 1:1 with the specified customer_uid. For security reasons, the server cannot directly access the billing key. Subsequent payments can be requested by calling the non-authenticated payment request REST API with the customer_uid as follows:

sever-side
curl -H "Content-Type: application/json" \
     -X POST -d '{"customer_uid":"your-customer-unique-id", "merchant_uid":"order_id_8237352", "amount":3000}' \
