Added ability to delete multiple tags
You can now select multiple entries on the Tags page in the Mailchimp Transactional app and delete them in bulk.
Previously, you had to delete tags one at a time and confirm each deletion in a dialog box, which was time-consuming.
Added shipment-tracking fields to orders endpoint
The /ecommerce/orders endpoint now accepts tracking_number, tracking_carrier, and tracking_url** **fields for an order’s shipment-tracking details.
This addition is in preparation for a future feature to notify shoppers of the tracking number, carrier (e.g. USPS, FedEx), and tracking URL for their orders. You can populate these fields in advance so they are ready to use when classic automations fully support them.
