Going live

1. Save your latest changes

   Deploy publishes the saved version, so press Save first.

2. Press Deploy

   At the top right of the builder. If something needs fixing first, a list titled Fix these before you deploy names each screen; press Back to the flow, fix them, and try again.

3. Enter your shortcode

   The code your aggregator assigned to you, such as *384*55#.

4. Add a callback URL (optional)

   See the next section. Leave it empty if you don't need answers sent to your own system.

5. Copy the callback address

   After Deploy, copy the address under Callback URL for your aggregator and paste it into your aggregator's dashboard. The link under it opens the setup guide for your aggregator.

If you enter a Callback URL (optional) when deploying (a full https:// address on your own server), Asterisks sends it every caller's answers when a session finishes on an End Session or Flash Alert screen. Use it to record orders, registrations or votes in your own database.

{
  "sessionId": "ATUid_9f1c2...",
  "projectId": "your-app-id",
  "shortCode": "*384*55#",
  "phoneNumber": "233244123456",
  "status": "completed",
  "variables": {
    "cups": "2",
    "MobileNumber": "233244123456"
  },
  "completedAt": "2026-10-04T09:30:12Z"
}

• variables holds every saved answer and every value saved from your APIs.
• It is sent once, in the background, after the caller sees the last screen. Your server should reply within 5 seconds; it is not retried.
• Sessions that are cancelled, time out, or end on Collect Payment don't send it.

1. Edit and test as usual

   Changes in the builder don't reach callers until you deploy. Test them in the phone preview first.

2. Save, then Deploy again

   Enter the same shortcode. Callers get the new version from their next session.

3. Re-enter your Callback URL

   Each deploy replaces the callback URL. If you leave the box empty on a redeploy, callbacks stop.

The callback address for your aggregator stays the same, so you don't need to change anything there.

Topping up

1. Open Billing

   In the dashboard's left menu.

2. Press Top up

   Choose an amount, or enter your own, then press Continue to payment.

3. Pay

   Pay with mobile money or card. You return to a page that confirms your wallet has been topped up.

Settings → Usage history lists every top-up and session charge.
