Amazon Incentives API — a referral program with Amazon gift cards

Hey there, a short use case story — inspired by one of our customers, I tested the Amazon Incentive API to showcase the referral program integration with Braze and Voucherify. It's a solid piece of software. I particularly liked three features:
➡️ `/CreateGiftCard` is idempotent — the same request ID yields the same certificate, so there's no need to store them in the CRM.
➡️ You can prompt the API to return a specific error code using a request parameter. This is useful for bulletproofing the integration, especially when combined with predefined test cases.
➡️ The documentation might not have Stripe-like magic, but it's up-to-date and comprehensive. The only issue I encountered initially was with the Amazon authorization algorithm, but it turns out Postman offers a solution out of the box.
