This guide describes foundational Flow Builder definitions for both automation flow triggers and trigger filters. It includes templates, use cases, and additional resources. Flow Builder's intuitive drag and drop interface makes it easy to build, visualize, and manage your brand's campaign and automation SMS flows. Get started by hopping into Flow Builder or by selecting the template links under Automation Flow Triggers.
How Can You Use Flow Builder?
Send automatic, pre-scheduled weekly text messages to subscribers about your products, brand, or shop updates. See how here.
Give your subscribers an automated one-to-one relationship with your brand using Response Branching .
Create hyper-targeted flows based on subscriber information and responses to previous SMS interactions with your brand. See more here.
What are Triggers and Trigger Filters?
Triggers are events that kicks off an automation flow.
For example, if you would like a subscriber to receive your automation flow after they place an order, the trigger, Order Created, is what adds the subscriber to that automation queue and kicks-off the automation for that subscriber.
Trigger filters fine-tune when an automation is triggered.
To use the example above, if you would like a subscriber to receive your automation flow after they place an order, but only if the one of the line items is shampoo, the trigger filter, Line Items | Name equals Shampoo, is what refines the Order Created trigger. With these properties, only subscribers who purchase shampoo will receive this automation flow.
What are Filter Operators?
Filter Operators define how the filter criterion is related to the value. Below, we outline all available filter operators, operator's definition, and an example.
