Introducing the SupaEasy External API, Automate Your Shopify Functions Like Never Before

That’s why we’re excited to announce the launch of the SupaEasy External API, a powerful new feature that allows merchants, agencies, and developers to programmatically create, manage, and automate Shopify Functions through SupaEasy.

Whether you’re building discounts, payment customizations, shipping rules, checkout validations, or customer segmentation logic, you can now automate everything through a flexible and secure API.

And unlike many platforms that lock APIs behind expensive enterprise plans, we decided to do things differently.

The SupaEasy API is available on every SupaEasy plan, at no additional cost.

No upgrades. No hidden fees. No enterprise-only access.

Why the SupaEasy API Matters

Until now, Shopify Functions created with SupaEasy were configured through the app interface.

While SupaEasy remains the easiest way to build Shopify Functions, many merchants, agencies, and developers asked for more flexibility—the ability to connect SupaEasy with external platforms, internal tools, and automated workflows.

With the SupaEasy API, that’s now possible.

You can create, update, and manage Shopify Functions directly from your own applications, workflows, and business systems.

The SupaEasy API allows you to:

🚀 Automate Shopify Functions at scale

🔗 Connect SupaEasy with any external platform

⚡ Create dynamic workflows with Zapier, Make, n8n, and IFTTT

💳 Programmatically manage Discounts, Payments, Shipping, and Validations

🏢 Integrate with ERP, CRM, loyalty programs, and custom business tools

🔒 Build secure integrations with token-based authentication

Connect SupaEasy with the Tools You Already Use

The checkout is where revenue is made or lost. Even highly optimized stores experience cart abandonment, and one of the key reasons is friction during payment.

Customers may:

• Not find their preferred payment method
• Distrust unfamiliar options
• Feel overwhelmed by too many choices
• Drop off if the checkout feels slow or confusing

By optimizing payment methods, you can:

• Reduce checkout friction
• Increase trust and confidence
• Improve conversion rates
• Maximize revenue from existing traffic

With Ab Check, you can test these variables instead of relying on assumptions.
