Testing the Rule
Make sure the rule is set to Testing status
Confirm your test phone number is in the Test Group (General Settings)
From your test number, open the Customer Sign Up Mini App on WhatsApp and submit a test sign-up
You should receive the sign-up confirmation with your name filled in
If you set the Action type to Open Mini App, verify the button appears and opens the correct booking form
Verify you only receive this confirmation — not an order or schedule confirmation on top of it
Once verified, switch the status from Testing to Live.
