Triggers

Triggers start your workflow when something happens on your Shopify store, like when an order is created, a customer is tagged, or a product is updated.

Adding Metafields

By default, Shopify trigger data excludes metafield information. Use MESA’s Metafield Namespaces feature to add metafield data to your workflow’s trigger data.

For example, to include global metafields, you will need to include the "global" namespace.

If you use the Fields feature, MESA will automatically include metafield data associated with the trigger in the workflow trigger data.

Limiting trigger frequency

The (Frequency) Fields feature allows you to trigger a workflow (that starts with an Updated trigger) when specified fields are updated in Shopify, preventing the workflow from executing for every update. When using this feature with Created triggers, a workflow will trigger whenever a field is present and not blank.

If you wish to trigger a workflow when a tag is added to a Shopify product, you must use the Product Update trigger which responds to every update made to the product. Then, by using the Fields feature with "Tags" selected, this will allow your workflow to only trigger when a tag has been modified.

❗It is important not to edit enabled (live) workflows to add the Fields feature, as it may disrupt future automations. We recommend duplicating the workflow first.

Technical notes

• Using this feature limits your workflow to receiving only the data specified in your input fields from Shopify. For additional information, consider adding a MESA Retrieve step after the trigger.

• An "update trigger" starts the workflow when a field's value changes for the first time after setting the trigger. For instance, if your workflow uses a product update trigger for tags, any initial change to the product, like a title update, triggers the workflow if it's the first change to the tags.

• Using the Fields feature won’t limit what you see in MESA’s Testing and Variables features. All data and variables will still appear.
