Developer-first SMS API
Send single or bulk messages through REST endpoints using a dashboard JWT or an SA API key. Idempotency keys let you safely retry supported requests.
Campaigns & contact lists
Import or sync contacts, select a list, and schedule a campaign. Follow its progress and recipient outcomes from your account.
Tanzania phone validation
Format Tanzania mobile numbers consistently and see how character encoding and message length determine SMS parts.
Delivery status updates
Check message logs for provider acceptance and later delivery updates. Delivery reports arrive asynchronously, so a successful API response is not handset confirmation.
Exact credit billing
Credits are counted by SMS part. Review deductions and top-ups in the account ledger, with idempotent handling for supported retry flows.
Mobile money top-ups
Top up using the payment methods currently available in your account. Destination rates and credit options can change; check the live rate card before sending.
Custom Sender IDs
Request an alphanumeric Sender ID, provide the required details, and check its review status in your account.
Google Contacts sync
Connect Google Contacts to import eligible numbers into a SendAfrica contact list when you choose to sync.

Alongside messaging infrastructure, SendAfrica includes focused apps for wedding planning, event attendance, and contribution tracking.
Harusi
Wedding invitations & guest management
Harusi gives wedding organizers one place to prepare invitations, organize guest details, follow RSVP responses, and coordinate check-in. Keep the details surrounding your celebration easier to manage, from the invitation list to the welcome at the door.
Hudhurio
Event check-in & attendance
Hudhurio helps event organizers set up activities and manage attendee check-in and attendance records. Share a check-in link or QR code, review who has checked in, and keep event details and attendee messages in one organizer workspace.
Michango
Contribution collection tracking
Michango helps organizers manage community contribution collections without losing track of who pledged, what has been recorded as paid, and what remains outstanding. Keep contributor records and collection progress together, then use SendAfrica SMS to follow up when needed.
See your SMS from request to delivery report
Connect through the REST API or dashboard, retry safely with idempotency keys, and follow asynchronous delivery updates in your message log. A successful send response means the provider accepted the message; final delivery status arrives separately.

The principles behind SendAfrica
SendAfrica exists so teams can send SMS confidently across African mobile networks.
Reliability, by design
Use idempotency keys on supported send requests to make retries predictable. Follow the API guide for each endpoint’s behavior and retention window.
Made for local messaging
Format Tanzanian mobile numbers consistently and see how message length and character encoding affect SMS part counts.
Transparency you can audit
Review message activity and credit movements in your account. Delivery reports arrive asynchronously and update message records as they come in.
Pay as you send, no subscriptions
Pay for credits as you send. One credit covers one SMS part; your plan sets the API request limit, not the number of SMS parts in a send.
