Getting Started

Sign up for a free Lob account

Your API keys are located under Settings.

You'll use the SECRET API KEYS that begin with test. for your Test API key and live. for your Live API key.

In order to use the collections in this public workspace, you'll select the Lob API collection and fork it into your personal workspace.

You'll also want to setup environment variables. A short cut is to fork Lob Public Env from Lob's public workspace. You also have the option to create them yourself - see the image below.

Set the Current Value for LIVEAPIKEY and TESTAPIKEY to your Lob live and test API keys and click Save.

Make sure Lob Public Env is selected in the environment menu.
