To filter Shopify orders where a dispute event ocurred, you can add this filter under the Custom Filters section when creating or editing a Data Settings:

• Order Events Actions contains dispute

This will include only orders that contain an event action with the word "dispute", such as the following:

• dispute_created
• dispute_pending
• dispute_accepted
• dispute_won
• dispute_lost
• dispute_closed
• dispute_inquiry_created
• dispute_inquiry_escalated
• dispute_inquirity_closed

You can use the above event action values if you need to filter for a more specific dispute event.

On the "Templates" page, you can also use the template "Orders with Chargebacks/Disputes (Last 90 Days)" which already has the filter configured and includes the dispute dates and messages.

Note:  The Shopify API only exposes Events data that occurred within the last 1 year.
