Usage

1

Create Buttondown Account

First, create a Buttondown account.

2

Find API Key

From the Settings page, retrieve your API key.

3

Add Environment Variables

To securely access the API, we need to include the secret with each request. We also do not want to commit secrets to git. Thus, we should use an environment variable. Learn how to add environment variables in Vercel.
