The Mailgun API is built on HTTP. Our API is RESTful and it:
- Uses predictable, resource-oriented URLs.
- Uses built-in HTTP capabilities for passing parameters and authentication.
- Responds with standard HTTP response codes to indicate errors.
- Returns JSON.
Mailgun has published Libraries for various languages. You may use our libraries, or your favorite HTTP/REST library available for your programming language, to make HTTP calls to Mailgun. Visit our Libraries page to see HTTP REST libraries we recommend.
To give you an idea of how to use the API, we have annotated our documentation with code samples written in several popular programming languages. Use the language selector at the top to switch between them.
All API URLs referenced in this documentation start with the following base part:
Your Mailgun account may contain several email domains. To avoid passing the domain name as a query parameter, most API URLs must include the name of the domain you’re interested in:
When you sign up for an account, you are given an API key. You authenticate to the Mailgun API by providing your API key in the request. You can manage your API key in the ‘My Account’ tab of the Control Panel.
Authentication to the API occurs via HTTP Basic Auth. Use
api as the user
name and your API key is the password. Here is how you use basic HTTP auth with curl:
curl --user 'api:key-3ax6xnjp29jd6fds4gc373sgvjxteol0'
Or you can try the following API call right from your browser:
Keep your API key secret!
