Your server creates a payment through the API and redirects the customer to the hosted checkout. PHP & JavaScript SDKs, webhooks, and test mode included.
Create a payment link from your dashboard in one click and send it to your customer on WhatsApp, Messenger, or SMS. They pay on the same hosted checkout — you get verified instantly.

You install the Fastaar Android app on the phone that owns your MFS SIM and pair it with a 6-digit code. When a customer pays, the incoming bKash/Nagad SMS is forwarded securely and matched against the payment by TrxID and amount — usually within seconds.
Yes. Create a test-mode API key (fk_test_…) and test payments auto-complete on the checkout page without any real money or SMS, while webhooks fire exactly like production.
Any backend that can make an HTTPS request. We ship PHP and JavaScript SDKs, plus copy-paste examples for plain PHP, Laravel, and Node — see the docs.
No. You pay a flat monthly or yearly subscription. bKash/Nagad's own cash-out fees still apply to your wallet as normal.
The payment stays in "awaiting verification". You can see the customer's claimed TrxID in your dashboard and complete or reject it manually — nothing is lost.
Register, add your bKash/Nagad number, pair your phone, and take your first payment in minutes.
