Open Banking Africa: emerging banking APIs in 2026

Open Banking — programmatic access to bank accounts via standardized API — has revolutionized EU and US fintech since 2018 (PSD2). In Africa, the movement is slower but real in 2026: Stitch, Mono, Okra are opening African bank APIs.

TL;DR

- African Open Banking = programmatic customer bank account access (with consent).

- Players: Stitch (ZA, NG), Mono Connect (NG, KE, GH), Okra (NG, GH).

- Use cases: account aggregation, income verification, account-to-account payment.

2026 Africa Open Banking players

UEMOA (Senegal, CI): no standard open banking in 2026. BCEAO initiative ongoing for 2027-28.

Open Banking use cases

1. Income verification (enhanced KYC)

For credit / leasing fintech:

`ts

import { Mono } from '@mono.co/connect.js';

const auth = await Mono.authenticate({

publicKey: process.env.MONO_PUBLIC_KEY,

scope: 'auth,transactions',

customer: { id: customerId, email: customer.email },

});

const transactions = await mono.account.transactions(auth.accountId, {

start: '2025-05-01',

end: '2026-05-01',

});

const monthlyIncome = analyzeIncome(transactions);

`

No more scanned pay stubs!

2. User account aggregation

Personal finance app (à la Bankin / Linxo):

`ts

const accounts = await mono.user.accounts(userId);

const totalBalance = accounts.reduce((sum, a) => sum + a.balance, 0);

`

3. Account-to-account payment (PSP-less)

Instead of going through Stripe / Wave (1-3% fees), direct bank transfer via Open Banking:

`ts

const payment = await stitch.payments.create({

amount: 100000,

currency: 'NGN',

customerBankAccount: customerBankRef,

recipient: { account: 'merchant-account' },

});

`

~0.3% fees vs 2-3% card. But less fluid UX (mandatory bank auth).

4. Transaction categorization

For SME accounting SaaS:

`ts

const categorized = await okra.transactions.categorize(transactions);

// → { groceries: 350000, transport: 80000, utilities: 120000, ... }

`

Open Banking integration architecture

`

[User connects bank]

↓

[OAuth flow to bank (consent)]

↓

[Open Banking provider gets token]

↓

[Your app receives account_id]

↓

[API calls: balance, transactions, categories]

↓

[Encrypted storage + analysis]

`

Step 1 — account connection (frontend)

`tsx

'use client';

import MonoConnect from '@mono.co/connect.js';

export function ConnectBankAccount() {

function handleClick() {

const monoConnect = new MonoConnect({

onClose: () => console.log('Closed'),

onLoad: () => console.log('Loaded'),

onSuccess: async ({ code }) => {

await fetch('/api/banking/exchange-code', {

method: 'POST',

body: JSON.stringify({ code }),

});

},

key: process.env.NEXT_PUBLIC_MONO_KEY,

});

monoConnect.setup();

monoConnect.open();

}

return (

🏦 Connect my bank

);

}

`

Step 2 — code exchange (backend)

`ts

export async function POST(req: NextRequest) {

const { code } = await req.json();

const userId = await getUserId(req);

const res = await fetch('https://api.withmono.com/account/auth', {

method: 'POST',

headers: {

'mono-sec-key': process.env.MONO_SECRET_KEY!,

'Content-Type': 'application/json',

},

body: JSON.stringify({ code }),

});

const { id: accountId } = await res.json();

await prisma.bankConnection.create({

data: {

userId,

provider: 'mono',

accountId,

connectedAt: new Date(),

},

});

return NextResponse.json({ success: true });

}

`

Step 3 — data pulling

`ts

async function syncBankAccount(connectionId: string) {

const connection = await prisma.bankConnection.findUnique({ where: { id: connectionId } });

const accountRes = await fetch(https://api.withmono.com/accounts/${connection.accountId}, {

headers: { 'mono-sec-key': process.env.MONO_SECRET_KEY! },

});

const account = await accountRes.json();

const txRes = await fetch(https://api.withmono.com/accounts/${connection.accountId}/transactions?start=2026-04-01&end=2026-05-01, {

headers: { 'mono-sec-key': process.env.MONO_SECRET_KEY! },

});

const transactions = await txRes.json();

await prisma.bankAccount.upsert({

where: { connectionId },

update: { balance: account.balance, lastSyncedAt: new Date() },

create: {

connectionId,

balance: account.balance,

currency: account.currency,

institution: account.institution.name,

},

});

await prisma.transaction.createMany({

data: transactions.data.map(tx => ({

bankAccountId: account.id,

externalId: tx._id,

amount: tx.amount,

type: tx.type,

date: new Date(tx.date),

narration: tx.narration,

category: tx.category,

balance: tx.balance,

})),

skipDuplicates: true,

});

}

FAQ

Q: Open Banking in Senegal?

A: Not standard yet 2026. Workaround: individual bank API integration (SGBS, Société Générale, BNP, Ecobank) — each with limited own APIs.

Q: Bank data security?

A: Read-only by default. End-to-end encryption. User-revocable tokens.

Q: Integration costs?

A: Mono Connect: 50-500K NGN setup + $0.05-0.30/req. For startup, ~$2-10K/month per volume.

Conclusion

African Open Banking in 2026 = early-stage but critical for serious fintechs. Nigeria-Kenya-Ghana in pole position. UEMOA following. Investing in the tech now = durable competitive advantage when other countries wake up.
