Automate with Shopify Flow

Run a workflow when a schedule starts, ends, fails or finds an edit, and start, end or create schedules from Flow.

2 min readUpdated November 4, 2026

Metascheduler adds triggers and actions to Shopify Flow. Triggers are on every plan. Actions are on Extra and Unlimited. You'll find both in Settings > Flow, with Open Flow.

Triggers

Every trigger gives your workflow the Schedule ID, Schedule name, Timing (AT, WINDOW, RECURRING or ROLLOUT), the Rollout ID (or nothing) and the Resources it changed. Long lists are cut to fit Flow's size limit.

TriggerRuns whenExtra fields
Schedule startedA schedule makes its changes.
Schedule endedA schedule's changes end or are changed back.
Change failedA change couldn't be made on some items.Target, Error message
Drift detectedSomeone changed an item after Metascheduler did, so it wasn't changed back.Target, Resource ID

Target is the change type's key, like variant.price or product.status (see Change types).

A workflow that emails the team when a price change fails.

Actions

Start schedule nowMakes a schedule's changes now.Schedule ID
End schedule nowEnds a live schedule now and changes its items back.Schedule ID
Create schedule from templateCreates a scheduled schedule for the items you pass.Template, Resource IDs, Start time, End time, Schedule name

A Metascheduler trigger gives you the Schedule ID to pass to an action.

Create schedule from template

Template is one of:

TemplateChangesResource IDs are
product-activeProduct status to ActiveProduct IDs
product-draftProduct status to DraftProduct IDs
product-unlistedProduct status to UnlistedProduct IDs
metaobject-activeMetaobject status to ActiveMetaobject entry IDs
metaobject-draftMetaobject status to DraftMetaobject entry IDs

Resource IDs are Shopify IDs, one per line or separated by commas. Start time is an ISO 8601 date and time with its offset. Leave End time empty to keep the change, or set it to revert then.

text
Template:      product-active
Resource IDs:  gid://shopify/Product/8123456789
               gid://shopify/Product/8123456790
Start time:    2026-11-27T09:00:00+01:00
End time:      2026-11-30T23:59:00+01:00
Schedule name: Black Friday drop

Plan limits apply to schedules made from Flow, the same as in the app. If an action fails, the reason shows in the workflow's run log.

Ideas

  • Change failed → send an internal email or a Slack message to the person who runs the sale.
  • Drift detected → add a note to the product, or ping the team that edited it.
  • Schedule started with a ROLLOUT timing → post in your launch channel.
  • A product is tagged pre-order → Create schedule from template with product-active at the launch date.

Schedule executed (legacy) fires only for schedules moved over from the old version of Metascheduler. For new workflows, use Schedule started.
