I am planning to have multiple phone numbers (Whatsapp for example), routed to the same Twilio Flow.
As per https://www.twilio.com/docs/studio/user-guide, I should be expecting a Twilio phone number that I can use to split the flow by:
Flow Variables include:
The Flow's Execution Sid: flow.sid
The Flow's address (e.g. Twilio phone number): flow.channel.address
When I tried this on a Whatsapp Sandbox it returned my channel SID instead. How else can I split my flow to different branches depending on my Twilio phone number (not to be mistaken with the customer's phone number) that the customer is connecting with?
As a note, I understand this can be done by assigning different Flows to different phone numbers, but it seems like an unncessary duplication.
It should be {{trigger.message.To}}. That will return the Twilio number the person sent the WhatsApp message to. You can use this varible in the Split Based on Widget to route to to a particular path in the shared Studio flow.
You can look at the Studio execution logs for for your Studio flow (under Logs > Click an Execution SID > Expand Trigger > Click on Widget & Flow Properties).
