Why integrate API with Thanks.io

The API to Thanks.io 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.

Send a handwritten postcard the moment an order is placed

When a Shopify order is placed, MESA triggers a Thanks.io postcard to the customer's shipping address automatically. Your store delivers a physical, personal touch without anyone writing or mailing a single card by hand.

Reach lapsed customers with direct mail when digital channels go quiet

When a customer passes a re-engagement threshold in Shopify — no purchase in 90 days, a dropped loyalty tier, an unsubscribed email — MESA triggers a Thanks.io postcard to their address. Your win-back effort reaches them on a channel that doesn't compete with a crowded inbox.

Send direct mail at the loyalty milestones that matter most

When a customer hits a VIP tier, a spend threshold, or a significant anniversary in Shopify, MESA triggers a Thanks.io card with a personalized message. Your best customers receive a physical acknowledgment at the moment it means the most without anyone manually curating the send list.

Build any API and Thanks.io 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.
