SMS for banks and SACCOs in Malawi

Three ways to connect

• HTTP API. Your core banking or SACCO system calls one endpoint when a transaction posts. Add an Idempotency-Key with the transaction id, so a retry never sends or charges twice.
• Verify API. For login and payment codes. It makes the code, checks it and limits abuse, so your team does not have to build that part.
• SMPP bind. If your switch or banking platform already speaks SMPP, connect it directly from fixed IP addresses.

What institutions should plan for

An alert is only useful if you can prove what happened to it. Every message has a status you can read from the API, and a signed webhook can write the final status back to your own records. Set a validity period on short-lived messages, so an old code or alert stops trying after a few minutes instead of arriving late.

Members trust a name they recognise, so request your sender ID early and use it for everything. Tell members which name you text from and that you will never ask for a PIN by SMS. That one line makes fake messages easier to spot.

For smaller SACCOs

You do not need a developer to start. Export your member list to Excel, upload it, and send a meeting notice or a dividend update from the dashboard. Merge fields can fill in each member's own balance or amount due, so one upload becomes a personal message for everyone. The Excel guide shows how.
