What Data is Passed

Event Name	Description	Properties
reorder_reminder (api)		Dynamic item variables: `[[item.title]]` `[[item.quantity]]` `[[item.price]]` `[[item.image]]` Personalization Variables: `[[event.customer_name]]` `[[event.discount_text]]` `[[event.discount]]` `[[event.reorder_link]]` `[[event.reminder_link]]`

This data allows Omnisend to segment customers and trigger automated messages based on reorder intent and past purchase behavior.

Use Data in Automation

Create an automation workflow based on the reorder_reminder (api) event as a trigger. Cross-check that the trigger type is set to reorder_reminder (api).

Use Dynamic Content

In email content, use dynamic variables, which you can use inside text, image, or button blocks within your Dynamic Content section. These variables will automatically populate based on the product data passed with the reorder_reminder (api) event.

Variable	Description
`[[item.title]]`	Product title
`[[item.quantity]]`	Quantity ordered
`[[item.price]]`	Product price
`[[item.image]]`	Product image URL

Add Personalization and Conditional Content

Personalization Variables:

Variable	Description
`[[event.customer_name]]`	Customer’s name
`[[event.discount_text]]`	Discount text
`[[event.discount]]`	Discount value
`[[event.reorder_link]]`	Reorder link
`[[event.reminder_link]]`	Reminder link

Conditional Syntax Example:

[% if event.customer_name %]
  Hi [[event.customer_name]]!
[% endif %]

[% if event.discount_text %]
  [[event.discount_text]]
[% endif %]

This shows content only when the variable has a value.

Add Action Buttons

In the left panel, drag and drop two buttons block. Click on the button to edit text and link. The first button opens the reorder link, and the second opens the order details.

Note: The second button is only needed for customer-defined reminders. If you're using usage-based or AI-based reminders, skip it.
