Introduction

The LegallyMail API allows you to send certified emails from your application. All sends are recorded and you can obtain legal certificates of delivery and reading.

Note: Only users who have made at least one payment can use the API and create tokens.

Test the API

Authentication

All API requests require authentication via an access token. You can get your token from the user panel.

Method 1: Authorization Header

Include the token in the Authorization header:

Authorization: Bearer YOUR_TOKEN_HERE

Method 2: In request body

Include the token in the JSON body:

{
  "token": "YOUR_TOKEN_HERE",
  "recipient": "example@example.com",
  ...
}

Get a Token

To get an API token, you must first have made at least one payment. Then you can create tokens from your user panel.

Endpoints

POST /api/send

Send a certified email.
