Getting started

Fastaar lets you accept bKash and Nagad payments on your website — even without an official merchant account. Customers send money to your MFS number, enter the transaction ID on a hosted checkout page, and the Fastaar Android app on your phone verifies the payment automatically by reading the confirmation SMS.

1. Register and complete onboarding

Register as a merchant — a four-step wizard walks you through everything: choosing a plan (pay via bKash/Nagad and submit the TrxID), adding your first MFS number, pairing your phone, and creating your first API key. Your subscription is activated after a quick manual verification.

2. Manage MFS accounts

Under MFS Accounts, add more bKash/Nagad numbers any time. Personal accounts receive Send Money; official merchant accounts receive Payments — both are verified through the mobile app, and the checkout page shows the right instructions automatically.

3. Keep your phone paired

The Fastaar Android app on the phone that owns your MFS SIM forwards incoming bKash/Nagad SMS so payments verify automatically. Pair more devices under Devices and keep at least one online.

4. Create your first payment

No website? Use the Create payment link button on the Payments page in your dashboard — enter an amount, copy the link, and send it to your customer on WhatsApp or SMS. They pay on the hosted checkout and it verifies automatically.

For website integration, start with a test-mode key (fk_test_…) so no real money is needed, then:

curl -X POST https://fastaar.com/api/v1/payments \
  -H "Authorization: Bearer fk_live_..." \
  -H "Content-Type: application/json" \
  -d '{"amount": 500, "metadata": {"order_id": "ORDER-42"}}'

The response includes a checkout_url — redirect your customer there. Continue with the website integration guide, the SDKs, and Webhooks.
