When you head over to the [Underdog API Postman](https://www.postman.com/underdogprotocol/workspace/underdog-api/overview), you'll hit an overview page with recent activity to the Postman workspace. We'll continue making updates to the workspace as API functionality grows.
## Getting Started
On the left hand side, click the desired API endpoint: **Mainnet API** or **Devnet API**. Within the collection page, hit the **Variables** tab to set the `apiKey` variable in your workspace.
Your API Key can be generated from the Underdog Protocol dashboard when you sign in.
Where you can set the apiKey variable in Postman
{% hint style="info" %}
The Devnet API is free to use and the same API Key you generate can be used for both endpoints. You will need a subscription to use the Mainnet API.
