# Bruno collections Explore and develop requests to APIs with Bruno. [Bruno](https://www.usebruno.com/) is a desktop application for API development which is similar to Postman. With Bruno, you can send requests to HTTP APIs, store request templates, and share them with others. commercetools provides [Bruno collections](https://github.com/commercetools/commercetools-api-reference/tree/main/bruno) for the APIs, including the [Audit Log](/api/history/overview/), [Checkout API](/checkout), and [Import API](/api/import-export/overview.md). These collections contain a complete library of templates for every possible request to API endpoints. commercetools Bruno collections are automatically generated from the latest [API reference](/dev-tooling/api-specifications.md) and include all supported endpoints and update actions with example bodies. As Bruno collections are file-based, you will update them when you pull the latest commits from the repository. To use the Bruno collections, you must download your API Client credentials and save them in the `environments` folder of the Bruno collection. You can then select this environment in Bruno and use **auth > Client Credentials** to receive an access token. This token is automatically used by further requests in this collection. After [creating an API Client](/api/getting-started/create-api-client.md#create-an-api-client), you can download an environments file for the collection by selecting **Bruno (Postman alternative)** from the drop-down. ## Download Bruno collections - [Main collection](https://github.com/commercetools/commercetools-api-reference/tree/main/bruno/api) - [Audit Log API collection](https://github.com/commercetools/commercetools-api-reference/tree/main/bruno/history) - [Checkout API collection](https://github.com/commercetools/commercetools-api-reference/tree/main/bruno/checkout) - [Import API collection](https://github.com/commercetools/commercetools-api-reference/tree/main/bruno/import) ## Related pages - [Area overview page with navigation](/dev-tooling.md) - [Previous page: Postman collections](/dev-tooling/postman.md) - [Next page: API specifications](/dev-tooling/api-specifications.md)
