Write 75% less code by letting our SDK do the heavy lifting
Why integrating through a Reloadly SDK beats calling our API endpoints directly — and which languages we support.

SDKs (Software Development Kits) are a comprehensive collection of tools that let developers build software applications faster and in a more standardized way. Reloadly's libraries and SDKs let you interact with our APIs without writing the integration logic yourself.

SDK vs. API: what's the difference?
In modern software development, the SDK and the API are two tools you'll run into constantly, and they're often confused for each other. At their core, both let you extend your application's functionality — but understanding how they differ matters for building a good experience, both for your team and your end-users.
An API is the raw set of endpoints you call directly. An SDK wraps those endpoints in a ready-made library — handling auth, retries, and formatting for you — so you write far less integration code to get the same result.
Supported languages
We've invested heavily in building SDKs across the most popular programming languages:
Java — also works for Android
Node.js
iOS
.NET
Golang
5 reasons to use the SDK instead
1. Access to constituent parts and instructions
Like a retail SDK that pulls in everything you'd want — favorites, cart, save for later, checkout — Reloadly's SDKs bundle the pieces you actually need.
2. Faster, smoother integrations
No need to call different endpoints for Airtime, Gift Cards, and Utility Payments separately — one single SDK covers all of it.
3. Shorter development cycle
Because the SDK handles the groundwork, your team focuses on the product itself. Expect to write ~75% less code than calling our API endpoints directly.
4. Built-in support and expertise
No need to write logic for fetching or refreshing an expired auth token — the SDK handles that under the hood, pre-loaded with the expertise and documentation already baked in.
5. Cost control
All of the above adds up to sticking closer to budget, during development and after launch. Time and effort drop by roughly 50% compared to calling our API endpoints directly.
Manually calling APIs vs. using the SDK
Here's the difference in shape: calling the API directly means you write and maintain the integration code yourself before anything reaches Reloadly. With the SDK, that layer is already built for you.

On the left, you maintain the entire integration layer yourself. On the right, the SDK already is that layer — you only write the part specific to what you're sending.
