Standard integration

First phase of the integration only requires basic features. Better cure rates can be obtained through a more advanced integration.

Frontend

Embed and invoke this component on your checkout pages.

SenseJS: FlexCharge needs to receive the customer's activity fingerprinting with SenseJS.

Backend

Incorporate these API calls in your transaction flow.

Tokenization: for every customer going through your checkout page, you have to encrypt the credit card information with FlexCharge, and store the returned token in your customer database.
Transmit: on successful transactions, queue a call to /transmit. FlexCharge will build your custom risk model based on your successful transactions.
Evaluate: send your declined transactions to /evaluate for FlexCharge to analyze then rescue/decline it.

Advanced integration

Additional features will increase your cure rate.

Outcome: for async calls, retrieve FlexCharge's response with /outcome or via a webhook.
