A NATURAL PART OF YOUR PRODUCT

They already trust you with their money.
Give them more ways to use it.

A data renewal on the way to work. An electricity payment at home. A cable subscription before the weekend. Bring those everyday moments into the product you already built.

WALLETS & FINTECH APPS

More reasons to open your app

Give customers a place to buy data and pay bills alongside the financial services they already use.

MERCHANT & CUSTOMER PLATFORMS

A new service in your existing flow

Add bill payments to your portal or checkout. Keep your own interface, account experience and customer communication.

DEVELOPMENT TEAMS

One integration to build around

Use a shared authentication pattern across four services, with request examples in Node.js, PHP, Python, Ruby and cURL.

MORE THAN AN API CALL

Real needs.
Right inside your app.

A customer needs data for the day. A household needs to renew its electricity. Give them a familiar place to get it done, without building every provider connection yourself.

BEYOND THE PURCHASE BUTTON

A payment flow your team can follow.

Your integration needs to explain what happened after a customer taps Pay. Strongmb gives you references, transaction lookups and webhook events to connect each outcome to your order.

Keep the customer experience yours.

Your backend talks to Strongmb. Your app decides how to display products, confirm purchases and communicate the result.

FOR THE TEAM MAKING THE DECISION

Inspect the details.
Make an informed choice.

Start with the questions your product, engineering and operations teams will ask.

ENGINEERING

Does it fit our stack?

Inspect the endpoints, payloads and response fields. Use standard HTTP clients from your backend.

Read the API reference QUALITY ASSURANCE

Can we test the edge cases?

Try documented success and failure fixtures, plus sample transaction lookups, before live purchases.

See the sandbox fixtures OPERATIONS

Where do we check service status?

Check the public status page when investigating a service issue, alongside your transaction records.

YOUR FIRST CONNECTION

Let your engineers try it.
Before you commit.

Evaluate the API in your own stack. Start with an authenticated account request, then test purchases, failed outcomes and transaction lookups using documented sandbox fixtures.

  1. Create your accountOpen Developers in your dashboard to find your keys.
  2. Try the sandboxUse the documented test products and customer details.
  3. Connect your checkoutChoose a product, submit the purchase and verify its outcome.
Follow the quickstart
Node.js · Sandbox 
const response = await fetch(
  'https://sandbox.strongmb.ng/v1/user',
  {
    headers: {
      Authorization: `Bearer ${process.env.STRONGMB_API_KEY}`
    }
  }
);

const result = await response.json();
console.log(result);
Run on your server with your test secret key. Keep keys out of browser code.

BEFORE YOU START

A few things to know.

Can I test before making live purchases?

Yes. Use the sandbox host, your test secret key and the test values in the sandbox guide. Switch to live credentials and live products when your integration is ready.

Can I add this to an existing website or app?

Yes. Send requests from your backend and build the payment screens in your existing interface. Keep your secret key on your server.

How do I get product prices?

Fetch the product list for the service you need. Product items include the applicable price, discount or minimum amount. Check current values before purchasing.

What if a purchase is still processing?

Keep the order pending and verify its status using the original reference. A timeout is not a failed purchase. Webhook updates help you keep the order in sync.
