# Postman collection & environment

> Test the hosted STE API with a ready-made Postman collection and environment, including payCalcRequest examples for federal, state, city, county, and multi-state scenarios.

Use the Postman collection to explore every hosted STE API endpoint without writing code. Pair it with the environment file below so requests pick up the right base URLs and your API key.

## Postman collection

The collection contains sample requests to all endpoints, along with `payCalcRequest` examples for federal, state, city, county, and multi-state scenarios. Additional examples for specific wage types and benefits are included as well.

  Import this file into Postman to get sample requests for every endpoint.
</Card>

## Postman environment variables

The environment file provides the variables used across the collection's requests. You'll still need to supply your own `apiKey`, which is provided by Symmetry's Client Success team.

  Import this file into Postman, then set the variables below for your target environment.
</Card>

Set these three variables for the environment you're testing against:

| Variable        | Staging                                           | Production                                |
| --------------- | ------------------------------------------------- | ----------------------------------------- |
| `apiKey`        | Your staging API key                              | Your production API key                   |
| `endpointURL`   | `https://ste-staging.symmetry.com/ste-hosted/v1/` | `https://ste.symmetry.com/ste-hosted/v1/` |
| `endpointURLV2` | `https://ste-staging.symmetry.com/ste-hosted/v2/` | `https://ste.symmetry.com/ste-hosted/v2/` |

<Note>
  Staging and production use **separate** API keys. If you don't know your API key, open a ticket with Client Success and we'll be happy to help.
