Connect API to Shopify Flow and automate your tasks

Why integrate API with Shopify Flow

The API to Shopify Flow 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.

Extend Flow automations into apps outside Shopify's ecosystem

When a Shopify Flow workflow reaches its limit — an action that requires a third-party app, an external system, or a more complex condition — MESA picks up where Flow leaves off. Your automations cover your entire stack, not just what Flow can reach natively.

Trigger MESA workflows from Shopify Flow events

When Flow completes an action — tagging a customer, updating an order, flagging a risk — MESA uses that signal to kick off the next step in a connected app. Your Flow automations and MESA workflows operate as a single, coordinated layer across your store.

Pass Shopify Flow data into your external tools automatically

When Flow processes an order, customer, or product event, MESA routes the relevant data to your CRM, email platform, or ops tools in real time. Your external systems stay current with what Flow is doing inside Shopify without a separate sync or manual export step.

Build any API and Shopify Flow 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.
