Quickstart Guide


In this Quickstart, send your first HIPAA compliant email via Paubox Email API in under 5 minutes.

Step 1: Sign up and create a Paubox account

It's free to sign up and to send up to 300 emails per month with Paubox Email API. Visit our sign up page and create an account.

If you send more than 300 emails in one month, you will be automatically moved up to the appropriate pricing tier and billed the annual cost.

Step 2: Add and verify your domain

Once you have a Paubox account, if you haven't already added a domain for the Paubox Email API, do so from the Paubox Email API > Settings page where you can Add a domain and verify that it's yours. 

Step 3: Generate an API key

From the Paubox Email API > Settings click on the domain you would like to generate an API key for, and then press the Add API Key button. Give the key a description and a new key will be generated upon submission. 

You can generate several API keys to use in different applications as needed. Make sure you save your key because if you lose it you will have to generate a new one.

To connect and send secure email, you'll need the API key and your customer endpoint, which is shown on the Paubox Email API > Settings page as well.

Step 4: Integrate the Paubox Email API into your application

The fastest way to get started is to use the Paubox Email API SDK repositories on GitHub

You can also checkout some quick samples on the Paubox Email API information page.
