Status: Integration programme

The 23 Telecom Journey Builder connection is available as a managed integration project. Contact us to scope your Business Unit, sender IDs, markets, throughput and delivery reporting. Live sending begins after custom-activity release and tenant activation.

What this connection does

The production design is a secure 23 Telecom Journey Builder custom activity delivered as an installed package. 23 Telecom provides a managed integration programme that scopes the Business Unit, hosted activity, credentials and delivery-report mapping, then coordinates rollout with your Marketing Cloud team.

Before you start

Prepare your Business Unit, Journey Builder environment, the data extension / contact key and phone field, approved sender IDs, markets, expected throughput and your DLR requirement. You’ll also want an active workspace.

Connect 23 Telecom

1. Ask your 23 Telecom account manager and your Marketing Cloud admin to scope the managed rollout:

   We’d like to activate 23 Telecom for SMS in Journey Builder. Please scope our Business Unit and share the onboarding plan and rollout timeline.

2. Share the Business Unit, phone field, sender IDs, markets and throughput — not credentials.

3. Once the rollout slot is confirmed, the teams configure the custom activity and run a tenant test. Live traffic starts after activity release and tenant activation.

What the full path involves

The complete integration is a separate product: a hosted configuration UI (config.json, customActivity.js, Postmonger), a server-side execute endpoint, Salesforce signature validation, server-only key storage, idempotency per execution, delivery-report mapping into a Data Extension or Salesforce event, Installed Package registration and tenant UAT. During rollout, the teams add it via Setup → Apps → Installed Packages → Add Component → Journey Builder Activity, then place the 23 Telecom tile in the test journey.

Verify the result

Accepted means queued; delivered is the later carrier report. During rollout, delivery is confirmed in 23 Telecom Message status or Statistics. The Marketing Cloud delivery mapping is included when agreed in the rollout scope and enabled after custom-activity release and tenant activation.
