Why this exists
A payment method that matches how Bangladesh actually pays
Card penetration is low. Phone ownership is not. Digimart turns the balance on a phone into a way to buy things from your app.
Money they already have
Most people in Bangladesh top up their phone but have never used a card online. Charging mobile balance reaches all of them.
One redirect, not a gateway
You do not build a checkout, store card details or pass a PCI audit. You send a signed URL and read the result.
Consent is not optional
Every charge is confirmed by the subscriber with a one-time password. You cannot silently bill anyone, by design.
You only pay when you earn
No signup fee and no monthly platform fee. Digimart takes an agreed share of what your subscribers are charged.
Two SDKs
Pick how you want to charge
That is the whole product surface. Recurring, or once.
Subscription Charging SDK
Recurring revenue, handled for you
Launching a subscription web or mobile app? Digimart runs the entire subscription lifecycle, opt-in, consent, renewal and cancellation, against the user's Grameenphone mobile account. You plug in the SDK; we handle the billing relationship.
Best for
- Streaming, news and content apps
- Learning platforms with monthly access
- Health, fitness and habit trackers
One-Time Charging SDK
Charge once, for exactly what they bought
Also called CaaS, Charging as a Service. Take a single payment of a specific amount from a user's mobile account: unlock a feature, buy a ticket, top up credits. No card, no bank account, no wallet signup required.
Best for
- Games selling coins, lives or skins
- Event tickets and one-off bookings
- Pay-per-download or pay-per-report tools
Start where you are
Every page tells you who it's for
One set of documentation, labelled by level. You are never dropped into a code sample you didn't ask for, and you can filter the whole sidebar to your level.
I want to understand the idea
What Digimart is, how the money moves, and what the jargon means, with no code anywhere on the page.
No coding required. Plain language, concepts only.
I want to set things up
Create an account, register an app and get it approved. Clicking through a dashboard, not writing code.
Your first hands-on steps. Clicking through a dashboard, not writing code.
I want to integrate it
Endpoints, signatures, callbacks and error handling, with copyable samples in several languages.
Code, endpoints and integration detail.
For developers
Two parameters and a hash
Build the signing string, hash it with SHA-512, and redirect. That is the integration. Everything else, from number capture to OTP, retries and consent screens, happens on our side.
