Source variable copies a dynamic value from the first channel in your sequence (e.g. the OTP sent on SMS). Static text inserts the same fixed words on every send, regardless of the message content.
Source variable (recommended for OTPs and personal data) #
Use when the WhatsApp or RCS step must show the same value the customer received on SMS.
Example: SMS variable holding OTP 482910 → map WhatsApp {{1}} to that source variable → WhatsApp shows 482910.
Static text (recommended for disclaimers and fixed lines) #
Use when the target channel should always include identical wording.
Example: RCS footer always says “Do not share this code with anyone.” regardless of OTP value.
Common mistakes #
- Leaving a target variable unmapped → save fails.
- Using static text for OTP → every customer gets the same wrong code.
- Not re-mapping after changing templates → placeholders may break.
