SimpliFi uses Async architecture to let the clients use its APIs in a modular set-up. Every API call made to SimpliFi would result in response code in the 2xx series, if the request was successfully received. Once the request is received it gets handled internally to get it processed.Once the request is processed, the response of the request is provided to the clients at their configurable endpoints through webhooks. Webhook body would provide appropriate values in case the request was completed as well as error codes in case the request resulted in failure.Understanding API Resources#
CardProduct: This is the highest level of the resource hierarchy with-in SimpliFi platform. CardProduct are implemented at the partnering processors depending upon client requirements and approvals from regulatory bodies and schemes.
Funding Source: Every client (or company i.e. client of SimpliFi client) would get a dedicated funding source in each approved currencies for CardProduct. Funding source is the Account number that is created to specifically run the card programs created under a Company.
User: Users are cardholders to whom the cards would be issued. Users can be created using APIs.
Card: These are payment cards which can be issued in virtual or physical form and can be used to conduct transactions. One user can have multiple cards.
PCI DSS Compliant SDK: Both iOS and Android SDKs which can be wrapped under client App to enable cardholders access their card details on the app.
Transactions: Transactions on SimpliFi platform could be accessed using two mechanisms:API: The API can be called to see all the transactions at Card, User or Card Program level. However this API would not be enough to update the client system with real time transactions.
Webhook: To support clients update their system with real time transactions (which the card holders would be conducting outside of their system), SimpliFi would send the webhooks with all the transactional details.
