API overview

The Gierd API gives your team a consistent way to send, receive, and manage commerce data across marketplaces without building a separate integration for each destination. Gierd acts as the integration layer between your systems and external channels, helping you move faster without taking on the complexity of maintaining one-off marketplace connections.

Why teams build on Gierd

One integration surface

Integrate with Gierd once instead of maintaining separate integrations for every marketplace or channel.

Built for system-to-system workflows

The API is designed for teams that need reliable, programmatic access to the operational workflows behind modern commerce.

Faster time to production

With a single platform handling common integration patterns, your team can spend less time rebuilding infrastructure and more time shipping.

Clear path for new development

The documentation is designed to help developers quickly understand what to use, where to start, and how to move from setup to implementation with confidence.
