3. Detailed steps
- Start checkout. Customer visits office top-up or scans a meter sticker that opens the same page with the meter pre-filled.
- Look up the meter. Search by customer name, meter address, apartment, or phone. If several matches appear, the customer picks the correct meter.
- Review account details. The page shows Atlantis Gas Supply as merchant (Tanzania), building/apartment, meter number, and remaining prepaid balance.
- Enter top-up amount in TZS. The UI shows estimated meter credit (and approximate m³) based on published gas pack / tariff settings. Limits enforce minimum and maximum top-up amounts.
- Enter phone (mobile money). For wallet payments, the customer confirms a Tanzania MSISDN (e.g. 2556… or 06…). Card checkout does not require a wallet phone for the charge itself.
- Accept legal terms. Checkbox links to Terms and Conditions, Refund Policy, and Privacy Policy. Payment buttons stay disabled until accepted.
-
Pay with mobile money or card.
- Mobile money: customer confirms the amount and phone; Atlantis sends an AzamPay MNO checkout request; the customer approves the push prompt on their handset.
- Card (Visa / Mastercard): customer is redirected to AzamPay hosted card collection, enters card details on AzamPay’s page, then returns to Atlantis top-up with a payment reference.
- Payment confirmation. AzamPay posts a webhook/callback to Atlantis. Only a successful payment status proceeds to meter credit. Failed, declined, cancelled, or abandoned checkouts do not credit the meter.
- Electronic delivery. Atlantis calls SMIMS RemotePay to credit the meter in meter currency. The customer status page updates to credited (typically under a minute when online). No physical goods are shipped.
