Progus Subscriptions does not ship Shopify Flow triggers or actions of its own. In the app, the Shopify Flow card is marked Coming later, and it says so plainly: Flow support stays as a guide for now, and a native connector can be added later without changing your current Klaviyo or tag setup. What follows is what works today.
Flow can already see everything the app tags. Open Settings → Integrations → Shopify tags, click Configure and note the tags for the events you care about. By default a first subscription order gets "Progus Subscription" and "Progus Subscription First Order", a failed renewal gets "Progus Subscription Failed Payment", and so on for recurring orders, prepaid, add-ons, pauses, cancellations and retention saves.
Order tags are the easiest entry point, but start from Flow's Order tags added trigger, not from Order created or Order paid. Tags are added shortly after the order, so a workflow on those two triggers runs too early to see them. From the tag trigger you can route the order, hold it, notify a warehouse, send an internal alert, or start a post-purchase sequence. A common first workflow is "when Progus Subscription Recurring Order is added, skip the welcome insert".
Some subscription events never touch an order. A pause, a cancellation, a retention save and a failed payment only tag the customer, so use Flow's Customer tags added trigger to catch them. That is how you alert your team on a cancellation, start a win-back sequence, or chase a failed renewal.
Watch out for loops. If a workflow is triggered by Customer tags added and also uses the Add customer tags action, it can trigger itself. Tag a different value than the one you listen on, or add a condition that stops the second pass.
Check or rename the tags first, since every workflow depends on them. See Tag customers and orders automatically.
For email and SMS automation, Klaviyo is the better fit today, because it receives real subscription events rather than tags. See Send subscription events to Klaviyo.
