This API facilitates "transactions" to deliver value to beneficiaries, such as mobile airtime top-ups and data bundles. A transaction progresses through distinct status stages, as illustrated in the following diagram

Final Statuses for Transactions

A final status is a status after which there are no further statuses. Note that SUBMITTED 5 and CONFIRMED 2 are NOT final statuses.

COMPLETED 7

The digital value service has been delivered. In rare cases, a successfully completed transaction can be reversed and assigned a REVERSED 8 status (so the definition for "Final Status" is applicable almost always).

REJECTED 3

The transaction was unsuccessful on DT One’s side.

CANCELLED 4

The transaction was canceled by the initiator before confirmation.

DECLINED 9

The transaction was unsuccessful on the provider’s side.

Two-Step Flow:CREATED 1 → CONFIRMED 2
- This approach is used when the initiator needs a short delay (e.g., to collect payment) between creating the transaction and submitting it to DT One.
- The maximum allowed time between the CREATED 1 and CONFIRMED 2 statuses is 60 minutes.
- If the transaction is not confirmed within 60 minutes, it will be automatically canceled.
One-Step Flow: Create a Confirmed transaction
- This approach is used by DT Shop, where transactions are created and confirmed in a single step.

Transaction Updates and Retrieval:

Real-time Notifications

When a callback URL is configured, the API sends real-time updates as the transaction status changes.

Transaction Status Queries

You can query the current transaction status using either the id returned by the API or your provided external_id.

External ID Usage

The external_id is essential for retrieving transaction details in exceptional scenarios, such as when an API response is not received.
