Why API integration

Why teams embed rewards via the API

When rewards are part of your product the API gives you control, native fit and ownership.

Rewards API integration workflow
1

Full control of the experience

Keep the entire journey inside your own site, app or checkout. Branding, layout, navigation and messaging stay yours.

2

A truly native experience

Rewards sit exactly where your users already are, with no separate site to visit. Less friction and better conversion.

3

Deeper data & personalisation

Combine Spendstream with your own customer data to tailor offers by user type, location, history, tier or campaign.

4

Your brand, full ownership

Spendstream stays invisible in the background. The rewards proposition reads as your own product feature.

5

Seamless reporting & reconciliation

Connect activity to your CRM, BI, finance and support tools for reporting that's genuinely operationally useful.

6

Built for established platforms

Ideal if you already have an app, logged-in users, a customer database and a product team. Embed, don't redirect.

Rewards API integration workflow
Two ways to deploy

API or white-label.
Two routes, one platform.

The same network of 4,000+ UK brands, same managed merchant relationships, fraud rules and fulfilment behind both. The only difference is how much you build and how much control you want.

API integration

Embedded in your own product

Spendstream rewards API integration

Best when:

You want full control and to embed rewards deeply into your own product, app or journey.

Time to market:

A development project on your side.

Build effort:

You build the front-end, user journeys, wallet logic, reporting and error handling.

Control:

Complete control of the customer-facing experience.

Maintenance:

You own and maintain the customer-facing experience over time.

Explore API integration
API is the better option when control, customisation and a fully embedded experience matter most. White-label is ideal when you want to launch quickly with minimal technical work, and you can always start with one and move to the other.

How it works

From access to embedded in four steps

You design the experience; we power the rewards engine and run the network behind it.

1

Get access

We provision your API credentials and a sandbox to build against.

2

Build & embed

Your team builds the front-end; our endpoints power gift cards, cashback, balances and redemptions.

3

Connect systems

Wire activity into your CRM, BI and finance tools for unified reporting and reconciliation.

4

Go live & expand

Launch one use case, then grow into a full embedded rewards layer over time.

Start with one use
case. Grow into a full rewards layer.

Shopper carrying bags outside a retail store

Begin with something focused - gift cards at checkout, or cashback in your member area.

Then expand into affiliate offers, user-level rewards, wallet features and automated incentives, all on the same API and merchant network, at the pace your roadmap allows.
