Connect API to Loop and automate your tasks

Why integrate API with Loop

The API to Loop integration helps you sync data, automate manual tasks, and keep your stack aligned — without writing code.

Pull live data into any Shopify workflow

When an order fires, MESA calls an external API and brings the response in as variables. Pricing feeds, fraud scores, or inventory levels from any service become available to every step that follows.

Send order details to your internal systems

MESA posts Shopify order data to your internal API or ERP the moment an order is created. Your operations and fulfillment tools stay current without custom middleware or manual exports.

Enrich orders with third-party data at checkout

MESA calls an external API at the moment of purchase — pulling fraud signals, shipping rates, or tax data — and uses the response to route or update the order before fulfillment starts.

Process every line item in an order individually

When an order arrives with multiple products, Loop goes through each line item one at a time — tagging, routing, or syncing each to a downstream system based on its specific data. One order, many targeted actions.

Update each product in a batch file one by one

When a CSV or FTP file contains multiple products, Loop processes each row individually — updating prices, inventory levels, or descriptions in Shopify without treating the whole file as one action.

Route each item to the right fulfillment location

For orders that split across multiple warehouses or vendors, Loop goes through each line item and sends the correct fulfillment request to the right destination. Every item reaches the right place.

Build any API and Loop automation

MESA helps you connect apps to automate repetitive tasks. A trigger is an event that starts a workflow, and actions are the steps that occur when it's running.
