Portal OTP
eTIN, civil status, land registry. WhatsApp code or PushMirror 1 tap for clerks. Same send() as the rest of the stack.
Ministries and agencies
The counter, on the phone.
Before the queue forms.
A tax desk, a commune, a ministry: citizens already live in WhatsApp. Zindua puts OTP, file status, and official waves on that thread, email for the archive, PushMirror when a clerk signs in from a new machine.
TIN login, counter tickets, city notices.
What you send
Public sector
TIN login, counter tickets, city notices.
Counter tickets
Fees received, document ready, window number. The citizen sees it in chat instead of waiting at the door.
City and ministry waves
Water, markets, polling places, health desks. Your lists. STOP + Guardian so the official number stays trusted.
Archive
Email when the notice must live in a dossier. Logs if an inspector asks who was told, and when.
On the ground
TIN login and a ticket that is actually ready
Not a passport copy paste. A Direction Générale des Impôts portal: the citizen asks for a code, pays the stamp, then gets “ready for collection” on the same official number. The paper file still exists. The second trip to the guichet does not.
- OTP for eTIN / one stop portal, 10 minutes, then it dies
- Ticket: fees paid, document ready, window B, bring the old card
- City wave: water cut, market day moved, polling station change, Guardian paced

How it works
Three steps. Same API.
Link the desk, map the templates, send when the file moves. One POST /send on every channel.
Step 01
Link the office number
QR in the dashboard. Display name = the desk citizens already know.
Step 02
Map the statuses
OTP, fees due, ready, pickup window. Templates in FR / EN / SW.
Step 03
Send from the portal
POST /send when the file moves. Campaigns for notices, never a burst.
