## Machine preamble

**Summary:** Import the Inttegro API into Postman or Insomnia with ready-to-use requests, shared variables, and a safe checkout workflow. This Python representation uses the selected SDK's native names wherever Studio has a verified mapping.

### Five questions

#### Q1. When should the reader use API collections?

Use this page as orientation before selecting the narrower guide or reference that owns the implementation contract.

#### Q2. What is authoritative on this page?

Use this page for orientation; follow its canonical SDK, guide, API, or MCP links for exact contracts.

#### Q3. What page-specific constraint matters most?

Use the page to choose a canonical next source instead of treating summary material as a complete implementation contract.

#### Q4. Can Inttegro MCP materially help with this task?

No catalog ability is sufficiently specific to recommend for this page. Use the documentation directly; consult the MCP catalog only if the task later requires governed live account context or a supported operation.

#### Q5. How should the reader verify the answer and continue?

Select the narrowest linked guide or reference, apply its stated completion condition, and verify against authoritative resource state when the task changes data. Continue with [Insomnia Import the shared environment and native Insomnia collections, with support for private sub-environments and Inso. Set up Insomnia →](https://studio.inttegro.com/machine/python/collections/insomnia.md) and [Postman Import the shared environment and the API-area collections you need, then run requests in Postman or Newman. Set up Postman →](https://studio.inttegro.com/machine/python/collections/postman.md) when those concerns enter scope.

## Document content

# API collections

Explore and test the Inttegro API in the HTTP client you already use. Both
collections cover every public operation and include shared variables, chained
resource IDs, response checks, and a safe hosted-checkout workflow. [Postman

## Before you send a request

Import the environment for your client, keep the published `api_key` value
empty, and store your real key only in a local or private environment. Replace
the example values required by the request you want to run.

Start with the included checkout quickstart. It creates a finalized order,
captures the order ID and hosted checkout URL, and looks the order up without
requesting or confirming payment.

:::warning Treat runtime values as secrets

Do not commit an exported environment containing API keys, one-time passwords,
confirmation tokens, or capability URLs.

:::

## What is included

The bundle is organized into focused collections for checkout and orders,
customers, payment methods, catalog, Purchase intents, financial accounts,
balances, payouts, messaging, one-time passwords, files, platform resources,
and refunds. Import only the areas you need; the shared environment lets them
reuse captured resource IDs.

## Collection versions

The Postman and Insomnia files are two representations of one collection
bundle. Its version follows the public Inttegro API contract, while Postman 2.1
and Insomnia 5.1 describe the client file formats. A contract release updates
both clients together so the same version always covers the same operations and
examples.
