What a gift card API actually does

A gift card API connects your own website, app or member platform to a digital voucher supply chain. Your product requests the available catalogue, creates an order and receives the information required to deliver the gift card to the customer. It removes the need for a customer to leave your experience and visit a separate marketplace.

Spendstream’s gift card capability sits within its broader rewards API. This page focuses specifically on digital gift cards; the main API page covers the wider rewards infrastructure, including other offer types and integration options.

The journey from catalogue to fulfilment

A typical integration begins by presenting eligible brands and products in your own interface. When a customer chooses a gift card, your application submits the order through the API and handles the response. The resulting voucher details can then be displayed or stored in the customer journey you have designed.

The important work continues after the first successful order. Product denominations, availability and other catalogue details change over time. Spendstream manages that supplier layer so your team is not maintaining an individual relationship and integration for every brand.

What your team builds and what Spendstream manages

Your team builds the front end, account experience, wallet logic and any connection to your own customer data. Spendstream provides the managed infrastructure behind the gift card transaction, including access to the product catalogue, fulfilment responses and operational reporting.

That division works well when rewards need to feel native to an established app or platform. If you do not want to build the customer-facing experience, the white-label gift card platform provides the alternative.

Payments, float and reconciliation

The commercial setup determines how orders are funded. A business may maintain a prepaid float, or customer payments may be handled through an agreed payment-gateway flow. Those routes affect the movement of money, but not the customer’s expectation that an eligible order should be fulfilled cleanly and recorded accurately.

Reporting should allow finance and operations teams to reconcile orders, customer value and any commission due. Spendstream manages the transaction and fulfilment layer around the gift card supply, while Tillo supplies and issues the gift card as our specialist infrastructure partner.

Implementation questions to settle early

Before development begins, agree who controls eligibility, where customers authenticate, how product availability is presented and what happens if an order is delayed or fails. Decide whether voucher details sit in an existing wallet, appear on an order screen or are delivered through another approved route.

Your developers can review the Spendstream API documentation alongside the commercial and operational design. This prevents a technically correct integration from producing a confusing customer journey.

When a gift card API is the right choice

Choose the API when your business already has a mature digital product, wants complete interface control and has development capacity for the customer-facing work. It is particularly relevant to fintech apps, membership products, employee-benefit providers and loyalty platforms that want gift cards to behave like an existing product feature.

Choose white-label when speed, lower internal effort and a ready-made customer experience matter more. The API versus white-label guide compares those trade-offs directly.
