1. Once you're signed in, click on the project drop-down and select or create the project you want to use for your Appian application.

2. Click on the navigation menu icon (☰) on the upper-left corner, then select "APIs & Services" > "Credentials".

3. On the Credentials page, click the "Create credentials" button and select "API key" from the dropdown menu.
