Customization in Transactional Messages

For Transactional Email, SMS, and Push, customization works differently compared to campaign-based content.

• Master contact and device columns are not used in transactional messages.
• Transactional sends are triggered via REST API.
• When making the API request, the data that should appear in the message content must be sent inside the request.
• This data is treated as current data.

Important Notes

• In transactional messages, only current data is available for customization.
• Contact columns and Device data cannot be used for personalization.
• All dynamic values must be provided within the API call.
