Moltin API Reference

Welcome to Moltin

Moltin is a headless eCommerce service that enables rapid experience-first commerce development & applications.

If you're new to eCommerce APIs as a concept or you're not sure how to evaluate what makes a good one, we recommend reading our eCommerce API 101 guide.

The Moltin API follows a microservice architecture that enables you to plug commerce into any part of your application. The API is built on the JSON API specification, follows predictable REST URLs and supports cross-origin resource sharing.

We have a two-track authentication layer that enables destructive and non-destructive actions across projects. All requests require an accompanying API key that is associated to users on your team.

If you do not have an account, project and API key already and would like to evaluate Moltin, please reach out and we would be happy to get you setup.


Moltin officially maintains and supports a JavaScript SDK, JS request library and Swift SDK. Other SDKs are community driven but happily hosted within the Moltin GitHub organization.


Moltin provides a variety of frontend and server-side example projects using various modern programming languages.


If you're looking to test or develop against our APIs, we recommend leveraging the Moltin Postman collection.


If you have any questions on how to use, improve or show off what you're building with Moltin, join us on Spectrum.
