Sinch Mailgun<\/a>\u00a0is a developer-focused email service that offers a RESTful API for sending, receiving, and tracking messages at scale. To experiment with these endpoints or troubleshoot an integration without writing code, you can use Postman, a popular API testing tool. Recently,\u00a0in another article<\/a>, we talked about how to integrate Sinch Mailgun with Postman. In this article, we’ll focus more on usage.<\/p>\n\n


Postman<\/a>\u00a0provides a fast and visual way to experiment with APIs. This makes it ideal for debugging and learning, or validating credentials without having to write any code. In this guide, you’ll use Postman to test and troubleshoot the Sinch Mailgun email API.<\/p>\n\n

Prerequisites<\/h2>\n\n

Before you get started, you need the following:<\/p>\n\n

A Sinch Mailgun account:<\/strong>\u00a0You need an active domain, or you can use the\u00a0sandbox domain<\/a>. You also need an\u00a0API key<\/a><\/strong>.
The Postman app:<\/strong>\u00a0Download<\/a>\u00a0and install the Postman app. Basic familiarity with requests and environments is helpful but not required.
<\/p>\n\n

Setting up Postman<\/h3>\n\n

To start, import the Sinch Mailgun collection and environment so you can start testing immediately. In Postman, click the\u00a0Import<\/strong>\u00a0button and use the\u00a0collection link<\/a>\u00a0to add the Sinch Mailgun collection:<\/p>\n\n


\"Importing<\/p>\n\n


Alternatively, fork\u00a0the Sinch Mailgun API<\/a>\u00a0from the Public API Network. Make sure you include the matching Sinch Mailgun environment:
\"Forking<\/p>\n\n


Next, you need to configure the environment variables. Open the Sinch Mailgun environment by selecting the\u00a0Gear<\/strong>\u00a0icon and then\u00a0Manage Environments > Mailgun<\/strong>. Enter your details exactly as shown:<\/p>\n\n

VARIABLE<\/strong><\/td>DESCRIPTION<\/strong><\/td><\/tr>
API_KEY<\/code><\/td>Your Sinch Mailgun API key)<\/td><\/tr>
BASE_URL<\/td>https:\/\/api.mailgun.net\/v3<\/code>\u00a0(US) or\u00a0https:\/\/api.eu.mailgun.net\/v3<\/code>\u00a0(EU)<\/td><\/tr>
mydomain<\/td>Your domain or sandbox domain (eg<\/em>\u00a0sandbox12345.mailgun.org<\/code>)<\/td><\/tr>
token<\/td>
Leave empty. This is used by the collection to generate the Basic Auth automatically.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n


Leave\u00a0token<\/code>\u00a0blank.<\/strong>\u00a0The collection auto-generates it from your\u00a0API_KEY<\/code>\u00a0using a pre-request script and handles authentication for you. Make sure you select Sinch Mailgun in the environment drop-down:
\"Sinch<\/p>\n\n


To verify the setup, in the\u00a0Domains<\/strong>\u00a0folder of the collection, open\u00a0Get domains<\/strong>\u00a0and click\u00a0Send<\/strong>. A successful response looks like this:
<\/p>\n
