Streamline your customer's journey with the Flex Pay Checkout API. This API enables a smooth transition from your merchant site to our Buy Now, Pay Later application and approval process. The API facilitates the purchase, returns Virtual Credit Card information for charging, and efficiently returns essential transaction data to Flex Pay.
Here's a sample of a checkout page with Flex Pay as a payment option. The "from $67/mo" below comes from the marketing API that can be used to generate a monthly price that will show a user suggested pricing. This can also be used when showing promotional items like 0% down, etc.

Flex Pay provides guidelines for the From-Pricing indicator, Infomodal and Payment Selector during the integration phase.
The implementation of the guidelines is the responsibility of the Merchant, using the raw data provided by the APIs. Deviations must be approved by Flex Pay as part of the compliance process.
Our compliance process continues to enforce strict compliance on behalf of our banking partners. Partners are expected to comply with our display guidelines, regardless if they code the integration by themselves.
