Campaigns

Send one message to a contact group, several groups, or your whole contact book. Created as a draft, dispatched when you say so, with live progress counters you can poll.

Campaigns live under /api/v1/ and authenticate with a scoped mbs_ token or JWT. A campaign targets contact groups (or an explicit phone list) and supports {{name}}-style personalization from your stored contact fields.

Draft first, send second

Creating a campaign never sends anything. It sits in draft until you call the send endpoint. Giving you a chance to review the rendered message and recipient count.

Send it

POST/api/v1/campaigns/{uuid}/send

Sending resolves the audience, computes total message parts, and reserves the SMS units from your balance up front: if the balance can't cover the whole campaign the call fails with an insufficient-balance error and nothing is sent. A scheduled campaign is queued for its scheduled_at time instead of dispatching immediately.

  -H "Authorization: Bearer $MOBILESASA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'

Track progress

GET/api/v1/campaigns/{uuid}

GET/api/v1/campaigns/{uuid}/recipients

Poll the campaign for live counters; the recipients endpoint pages through per-recipient delivery state.

curl "https://api.mobilesasa.com/api/v1/campaigns/c4e8a90d-…" \
  -H "Authorization: Bearer $MOBILESASA_TOKEN"

Response: 200 (sending)

Campaign statuses

Field	Type	Required	Description
draft	initial	No	Created but not sent. Editable (PUT) and deletable.
queued	in flight	No	Accepted for dispatch (or waiting for its scheduled time).
sending	in flight	No	Workers are fanning messages out; counters update live.
completed	final	No	All recipients processed. total_failed tells you how many didn't go out.
failed	final	No	The campaign as a whole failed; failure_reason says why (e.g. insufficient balance, no sender configured).
cancelled	final	No	Stopped via the cancel endpoint before finishing.

Cancel

POST/api/v1/campaigns/{uuid}/cancel

Cancels a draft or queued campaign. Handy for calling off a scheduled send. Cancelling a queued campaign releases its reserved units back to your balance. Once a campaign is sending it can no longer be cancelled.

Resend

POST/api/v1/campaigns/{uuid}/resend

Resending a completed, failed or cancelled campaign clones it into a new campaign (new UUID) and dispatches the clone immediately. The original and its stats stay untouched. The response is the new campaign; store its UUID for tracking.

curl -X POST https://api.mobilesasa.com/api/v1/campaigns/c4e8a90d-…/resend \
  -H "Authorization: Bearer $MOBILESASA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'

Resend re-bills

A resend targets the audience as it stands now (groups may have grown) and reserves units again at full price. Double-check you aren't about to message the same customers twice by accident.
