Key parameter description

pg *** **string
PG code
  • If not specified and this is the only PG setting that exists, default PG is automatically set.
  • If there are multiple PG settings, set to mobilians.[MID].
customer_uid *** **string
Credit card billing key
Billing key to be mapped 1:1 with the user-entered credit card information.
amount *** **Integer
Payment amount
Amount to display in the payment window, but actual payment approval is not processed. (To request payment, use the REST API with the customer_uid.)\

Request payment with billing key (customer_uid)

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}' \
