Cash Receipt API
This API allows an integration for your system to issue cash receipt and send to the NTS using identification information (cell phone number/resident registration number/card number) of a buyer. Depending on the type of buyers, seller can issue “tax deduction purpose” for an individual type and “proof of purchase purpose” for business proprietor type. POPBiLL cash receipt follows the [NTS cash receipt system provider file transmission and reception specifications] protocol and provides all types of issuance including general issuance/issuance for revocation.
POPBiLL provides independently constructed stages as “TEST” and “PRODUCTION”. In test setting, except for the NTS filing function that will be completed as a mock process, all the other functions operate identically as the production setting.
