# API Tools & Resources

This section provides the supporting assets for exploring and testing the eComm Checkout API. The attachments are designed to speed up onboarding and reduce implementation errors by offering both a formal API contract and executable examples.

***

#### OpenAPI (Swagger) specifications

> OpenAPI files represent the official API contract: endpoints, schemas, parameters, validation rules, and example payloads. These files are typically used as a reference during implementation and for troubleshooting request/response mismatches.

#### Postman assets

Postman assets provide ready-to-run examples. They are intended for quick testing in sandbox and for validating requests before implementing them in code.

#### **Postman Collection — Checkout API requests**<br>

Import this collection into Postman to access prebuilt requests for the Checkout API endpoints:&#x20;

{% file src="/files/vsHqldM8I2y7AveshvrU" %}
{% endstep %}

{% step %}

#### **Postman Environment — Sandbox variables**

Import this environment into Postman and fill in the placeholder variables locally (for example, `clientId`, `clientSecret`). Select this environment before running requests from the collection.
