Delivery status in AJO	No — check 23 Telecom
Who can configure	Journey Administrator

Status: Managed activation

23 Telecom supports Adobe Journey Optimizer through a custom action. Start with the sandbox recipe below; when you’re ready to launch, your account manager enables live sending and completes a short configuration check for response handling, idempotency and account throughput. On the current batch endpoint, confirm results[0].status is "accepted" with a non-empty results[0].message_id.

What this connection does

A Journey Optimizer custom action calls the 23 Telecom API to send an SMS from a journey. AJO records the action response; carrier delivery reports stay in 23 Telecom.

Before you start

• The Journey Administrator permission and a public DNS hostname / HTTPS.
• An active workspace, an approved sender ID and an E.164 test number, e.g. +447911123456.
• A restricted 23 Telecom API key with only sms.send — start with a sandbox sk_test_ key (Sandbox & test mode).

POST  /api/v1/sms/send-individual  · Permission: sms.send

Connect 23 Telecom

1. Go to Administration → Configurations → Actions → Manage → Create Action.

2. Set method POST and the URL https://restlink23telecom.com/api/v1/sms/send-individual.

3. Set authentication to API key, name X-API-Key, location Header.

4. Define the JSON request schema with to, message and a stable event ID, and keep sender_id as a protected constant.

5. Use Send test request, then add the action to a journey.

Field mapping

AJO action field	Value
Method	POST
URL	https://restlink23telecom.com/api/v1/sms/send-individual
Authentication	API key · header X-API-Key
Idempotency-Key header	a stable trigger event ID
messages[0].to	recipient phone variable (E.164)
messages[0].message	message variable
messages[0].sender_id	approved sender ID (protected constant)

Send a test

Use Send test request with your sk_test_ key before wiring the action into a journey. For the test, set the Idempotency-Key header to a fixed value such as ajo-sandbox-001.

A 2xx is not acceptance — check the response body

A 200 only means the request was received. Treat the message as queued only when results[0].status is "accepted" and results[0].message_id is present. blocked_country is not queued. Missing local pricing is different: valid live API traffic is accepted fail-open, and the delivery report supplies the final status and cost. If the body is not an acceptance, do not auto-retry until the 23 Telecom message log confirms that no message was accepted.

Idempotency, TPS & delivery

Adobe expects a target endpoint that can accept at least 200 TPS. Confirm (and if needed raise) your 23 Telecom account limit before a production rollout, or buffer through the integration adapter. Use a stable trigger event ID as the Idempotency-Key — do not assume a universal execution ID exists. The custom-action response is acceptance; a delivery report inside AJO needs a dedicated Adobe event.

Production activation

Live traffic uses managed activation because the custom action routes on the HTTP response. Your 23 Telecom team confirms a retry-safe path using the strict integration endpoint, where a 2xx guarantees acceptance, or an adapter that validates the response body, and aligns the TPS budget with Adobe.

The activation package includes the approved production URL or adapter mapping, the restricted key and a one-message launch check. Apply that configuration — rather than changing only the API key on the sandbox batch template — and then activate the journey.

Verify the result

Accepted means queued. Read carrier delivery in Message status or Statistics, or add a live delivery webhook.

Troubleshooting

Response	Cause & fix
400 IDEMPOTENCY_KEY_REQUIRED	Send the stable event ID as Idempotency-Key
401 INVALID_API_KEY	Wrong or disabled key in the header
403 NO_SMS_ACCESS	SMS not enabled — contact 23 Telecom
429 RATE_LIMIT_EXCEEDED	Above your per-second budget — raise the limit or slow the journey
