Automate Mirakl 1P Stock Status with Inventory Changes

Manually updating a 'has 1P stock' flag for every product variant, especially when syncing with marketplaces like Mirakl, is a massive time sink and prone to errors. Incorrect stock status can lead to cancelled orders, poor customer experience, and potential penalties, costing you valuable time and revenue.

This Shopify Flow instantly reacts to `Product variant inventory quantity changed` events. It intelligently checks if the inventory is available (and not from a marketplace fulfillment location) and whether the `mirakl.has_1p_stock` metafield needs an update. If stock becomes available, it sets `has_1p_stock` to `true`; if depleted, it sets it to `false`, ensuring your Mirakl integration always receives the correct, real-time status.

• You list products on Mirakl and need to signal direct-ship inventory (1P stock).
• You want to prevent overselling or underselling 1P stock on Mirakl due to out-of-sync data.
• You manage a large catalog where manual metafield updates are impossible to maintain.

1. 1

   **Set Trigger and Initial Condition:** Start a new Flow with the 'Product variant inventory quantity changed' trigger. Add a `Condition` block where `Location name` does `not start with` "MKP_" (to exclude marketplace fulfillment locations).

2. 2

   **Configure In-Stock Branch:** Inside the location condition, add an 'If' branch. Set the condition as `Inventory levels available` is `greater than 0`. Within this 'If' branch, add a nested `Condition` for `mirakl.has_1p_stock` being `equal to false` OR `does not exist`. Finally, add an `Update product variant metafield` action to set `mirakl.has_1p_stock` to `true` (Boolean type).

3. 3

   **Configure Out-of-Stock Branch:** After the 'If' branch from the previous step, click to "Add 'Else' branch". Within this 'Else' branch, add a `Condition` for `mirakl.has_1p_stock` being `equal to true` OR `does not exist`. Add an `Update product variant metafield` action to set `mirakl.has_1p_stock` to `false` (Boolean type).

What is the `mirakl.has_1p_stock` metafield used for?

This metafield signals to Mirakl (or a Mirakl integration) whether the stock for a particular product variant is directly managed and fulfilled by your store (1st party), rather than being dropshipped or fulfilled by a 3rd party.

Why is it important to filter out locations starting with 'MKP_'?

Many marketplace integrations use special location names (like "MKP_Amazon") to track inventory reserved for or fulfilled by those marketplaces. Excluding these ensures your 1P stock flag only reflects inventory available for your direct fulfillment.

What happens if the `mirakl.has_1p_stock` metafield doesn't exist yet?

The Flow is designed to handle this. If the metafield doesn't exist, the conditions 'does not exist' will evaluate to true, allowing the Flow to create the metafield and set its initial `true` or `false` value based on the current inventory level.

Can this Flow handle multiple fulfillment locations for 1P stock?

Yes, as long as the locations you consider 1P stock do *not* start with "MKP_", this Flow will correctly sum the inventory from all relevant locations to determine the overall 1P stock availability before updating the metafield.
