APIs for Africa: How to Build a Developer-First Product

6 min read

What African API startups need on day one, how to pick and price your API, and what Daraja 3.0, Paystack and the Okra shutdown teach infrastructure teams.

A developer-first API product lets an engineer sign up, get sandbox keys and make a first successful call without speaking to sales. In Africa the best openings come from wrapping a messy local system, such as mobile money, bank data or telco messaging, in one clear and well documented call. Reliability, documentation and honest pricing decide whether teams stay.

I co-founded Hackhouse, a builders' hub in Nairobi, and many of the products I see depend on someone else's API. This guide covers why the API layer matters here, what to ship on day one and what can go wrong. I checked every fact below on 5 November 2026.

Why do APIs matter so much for African startups?

Payments, identity, messaging and banking work differently in each country, with different currencies, telcos and regulators. A company that turns one of those systems into a single dependable call saves every team that builds on top of it weeks of work.

M-Pesa shows the scale. At the Daraja 3.0 launch in November 2025, Safaricom said its ecosystem had more than 66,000 API integrations and over 100,000 developers, and that 25% of all M-Pesa transactions now run through APIs (TechMoran). Daraja 3.0 moved to a cloud-native architecture and came with a redesigned sandbox for testing transaction flows before going live (Techweez).

Other examples sit across the continent. Paystack built for developers from Lagos, and Stripe acquired it in October 2020 to speed up online commerce across Africa (Paystack). Mono sells open banking APIs to African businesses (Mono). Africa's Talking offers SMS, USSD, voice, airtime and WhatsApp through official SDKs (Africa's Talking on GitHub).

What does a developer-first API need on day one?

The engineer evaluating you is often on a deadline with other options open. Give them these from the first release:

  • Self-serve sign-up and sandbox keys. Safaricom's Daraja portal lets companies and individuals register and create a sandbox app. Paystack publishes test details for each payment channel, and Africa's Talking uses a sandbox username for development.
  • Documentation that shows a full request and response in the languages your users write, with copy-ready examples.
  • Official SDKs. Africa's Talking maintains SDKs for Python, Node.js, Java and Ruby on GitHub, and several were updated in 2026.
  • A public status page and changelog. Paystack runs a status page that lists scheduled maintenance, and Mono links an API reference, changelog and status page from its site.
  • Webhooks with retries and signatures, so a dropped connection does not lose a payment notification.
  • Clear error messages that say what went wrong and how to fix it.
  • A versioning and deprecation policy written down before you need it.

How do I choose which API to build?

Pick one integration that many teams in your market build badly over and over, and make it one clean call. Resist the urge to launch a platform on day one. A short test before you write code:

  1. Talk to 10 developers or CTOs who would use it. Ask what they built themselves, how long it took and what breaks.
  2. Ask what they pay now, in money and engineering time.
  3. Write the documentation for the first endpoint before you build it, and show it to those same people.
  4. Ship a sandbox and watch two or three teams integrate it. Time how long it takes them to reach a first successful call.

Our guide to building a developer community around your product covers what comes after the first integrations.

How should I price an API product in Africa?

Most API businesses charge per call, per transaction or by monthly tier. Payment APIs usually take a percentage. Paystack, for example, charges 1.5% per M-Pesa transaction in Kenya with no upfront or monthly fees, and integration is free (Paystack pricing). Okra charged per API call and, according to Nairametrics, reached US$1 million in annual recurring revenue within 12 months (Nairametrics).

Whatever model you choose, keep the sandbox free and publish your prices. Engineers want to model costs before they commit, and a "contact sales" wall slows that down.

What can go wrong with an infrastructure startup?

Infrastructure carries a heavy promise. When your API goes down, your customers' products go down too, so reliability, support and documentation are ongoing costs from the first month.

Okra is the example most African builders know. Nairametrics reports that the Nigerian open banking company relied heavily on screen scraping, saw revenues shrink after its co-founder David Peterside left in October 2022, and wound down operations in May 2025. Co-founder Fara Ashiru said the company "made the decision to wind down operations in May" (Nairametrics). Every team that had built on its API needed a new provider.

Three lessons follow for anyone building infrastructure:

  • Build on stable, permitted access to the underlying system wherever you can, and know your exposure where you cannot.
  • Keep enough cash to run the service through slow sales periods, because customers depend on you staying up.
  • Write a shutdown and migration plan, including how much notice customers will get, and review it once a year.

If you are shaping an API product, our Hackhouse Residency runs for 12 weeks with no equity taken, and HH Gen 27.1 applications are open. You can also meet other builders at our community events. For the payments side, see our guide to integrating mobile money.

Key facts

  • Safaricom reported more than 66,000 API integrations and over 100,000 developers in November 2025.
  • 25% of all M-Pesa transactions go through APIs, according to Safaricom.
  • Daraja 3.0 launched in November 2025 with a cloud-native architecture and a redesigned sandbox.
  • Stripe acquired Paystack in October 2020.
  • Okra, a Nigerian open banking API company, wound down operations in May 2025.
  • Paystack Kenya charges 1.5% per M-Pesa transaction with no monthly fee.

Frequently asked questions

What is a developer-first product?

It is a product designed so engineers can discover, test and adopt it themselves. Self-serve keys, a sandbox, clear documentation and SDKs come first, and sales conversations come later.

How do I get M-Pesa API access in Kenya?

Register on Safaricom's Daraja developer portal as a company or an individual, create a sandbox app and test your integration. You then follow Safaricom's process to move to production.

What should API documentation include?

A quick start, authentication steps, full request and response examples, error codes with fixes, webhook details, rate limits and a changelog. Test it by asking a developer who has never seen your product to make a first call.

Why did Okra shut down?

Okra did not give a reason in its statement. Nairametrics reported a reliance on screen scraping and shrinking revenue after a co-founder left in 2022, before the company wound down in May 2025.
