Connect a WhatsApp Business number through SegmentStream's Meta app with Meta's Embedded Signup. A number already in the WhatsApp Business app keeps working there. Requests address the number and its account by alias, so code never handles their IDs.
Connected once, used everywhere.
Connections are declared in your repository and authorised in the console. The credentials stay with the platform; apps, pipelines, workflows and the agent use them under the same roles.

What the connection reaches
- Messages, read receipts and typing indicators from the connected number
- Message templates of its account, and media
- Optional contacts and chat history of a WhatsApp Business app number
- Status
- Built into the pipeline SDK
- Connection class
- WhatsAppConnection
- Credential
- Admin of the business portfolio that owns the number
Connect WhatsApp
Three steps, the same for every connection. The credential goes to the platform, never into the repository or pipeline code.
- 1
Declare it in connections/connections.py
connections/connections.py from segmentstream.connections import WhatsAppConnection connections = ( WhatsAppConnection(key="whatsapp"),) - 2
Deploy
$ segmentstream deploy - 3
Connect
Open the connection in the console and sign in with an admin of the business portfolio that owns the number, or authorise it from the terminal. Tokens are refreshed by the platform; pipeline code never sees them.
$ segmentstream connection authorize whatsapp --open
Use it
Code asks for the connection by its key. The platform adds the credential on the way out.
import segmentstream as s with s.get_connection("whatsapp").get_http_client() as client: response = client.post("/phone/messages", json={"messaging_product": "whatsapp", "to": "34600000000", "type": "text", "text": {"body": "Confirmed"}}) response.raise_for_status()Or ask your agent
“Connect our WhatsApp Business number and send booking confirmations from it.”
