Uploading orders
Use the order endpoints when your system needs to add or update the work that GREIT should pack. Pay attention to order IDs, section names, and whether an order is already in progress or completed.

GREIT Storage System
This is the public entry point for developers integrating with the GREIT storage system. The API is described with OpenAPI, so you can explore the available endpoints in a browser, test request and response shapes, or import the specification into your own development tools.
If you are new to the integration, start by opening the documentation in Scalar. It gives a readable overview of the order, inventory, urgency-planning, and webhook endpoints. If you already know what you are looking for, Swagger UI or the raw YAML file may be faster.
Before you build:
GREIT works with full stacks, not individual pieces, and product codes are case sensitive.
Treat IDs and product codes returned by the API as the source of truth when passing data on
to later steps in your integration.
Open the API documentation
Choose the documentation view that best fits how you work. Both viewers use the same OpenAPI specification, so the endpoint definitions, request bodies, response schemas, and callback descriptions are identical.
Open in Scalar
Best starting point for reading the API, searching endpoints, and reviewing examples.
Open in Swagger UI
Classic interactive API documentation for developers familiar with the Swagger workflow.
Download OpenAPI YAML
Use the raw specification in your editor, client generator, test suite, or documentation pipeline.
Where to start
Checking availability
Use the order and urgency views to understand what can be packed now, what is blocked by missing stock, and which products should be prioritized next in production.
Open urgency tools in ScalarReceiving events
Use subscriptions when your service needs callbacks from GREIT, such as when orders start, orders complete, items are stored, or items are rejected.
