# Getting Started Postman Collection

You will need to have [Postman](https://www.postman.com/) installed to run this tutorial. See the [Download](https://www.postman.com/downloads/) page for you operating system. 

## Import Postman Collection

This Postman collection is meant to get you quickly up and running and familiarized with the basics of the API.

{% endfile %}

You can import this into Postman with File -> Import, or with Import button.

Next we will cover how to set up an environment to start calling the API.&#x20;

## Import Environment

You need an Application with suitable scopes to run the collection. For full details, please consult the [guide section on Applications](https://guide.transmute.industries/verifiable-data-platform/technical-documentation/applications) for details on managing platform Applications. &#x20;

On the Transmute platform, go to Applications, and create a new Application. Select the \`Credentials\`, \`Presentations\`, and \`Organizations\` scopes which are required to run the collection. Click "Create Application" and download the Postman environment.&#x20;

In Postman, import the environment file as an Environment. Select it as the active environment in the top-right drop down. &#x20;

## Postman Collection Functionality

To run the collection, click on the three dots next to "Transmute Getting Started", and then click on "Run Collection.&#x20;

To run the entire collection, right-click the Collection and choose Run Collection to run all the endpoints in order.&#x20;

The Postman collection calls some basic network requests to the API:

* First obtains an access token for the application
* Queries and resolves the default did:web
* Issues a sample Verifiable Credential
* Illustrates different Verifiable Credential media type representations
* Verifies retuned and referenced Verifiable Credentials
* Signs a Verifiable Presentation
* Submits a Verifiable Presentation
