Preview flow on different channels
Preview a flow
Click the Preview button (top left of canvas).
Select the channel you want to preview the flow on.
Note: You can only select from those channels that have been set up in your account.
Add the test details for the selected channel.
Note: For testing purposes, this can be anything and does not have to be a real phone number.
Select the flow you want to preview using the Select Route drop-down (defaults to the flow currently in context).
To exit, click the Stop preview button (top left of canvas).
Preview on WhatsApp
Previewing the WhatsApp channel offers a rich experience, including media, location sharing, etc.
Click Start.
Type something in the text box and press Enter to trigger your flow.
There is an option to test your flow simulating BSUID. If you select this option, the "Mobile Number" field relabels to BSUID with placeholder "Enter a BSUID". Type a fake BSUID value (e.g. ZA 1234567890) into the field.
The emulator treats this as a BSUID-only message (no phone number in the webhook).
The Trigger Contact Book Flow check box will only be visible to users who have the Contact Book feature enabled.
Preview on SMS
The SMS channel preview provides a simpler, text-only experience including a character count so flow-builders can correctly structure their messages.
Preview on USSD
The USSD channel preview provides a similar experience to SMS, with shorter, text-only messages.
