BPS_API int paymentservice_event_get_number_purchases(bps_event_t *event)
The event to retrieve the number of purchases from.
Successful PURCHASE_RESPONSE and GET_EXISTING_PURCHASES_RESPONSE events contain an array of existing purchases. For a PURCHASE_RESPONSE event, the array will contain at most one purchase, so the index passed in should always be 0. For a GET_EXISTING_PURCHASES_RESPONSE event, retrieve the data for each purchase by first calling the paymentservice_event_get_number_purchases() function to determine the number of existing purchases that were retrieved. Then, retrieve the data from each index, where the index ranges from 0 to the number of purchases minus one. Get the number of retrieved purchases from a Payment Service event
