Uniform Resource Locator

A Uniform Resource Locator (URL) is a unique string of text that points to a specific resource on the internet, like web pages or web domains. A URL includes a protocol (like HTTP or HTTPS) and domain or resource name, and sometimes a path, which indicates the specific location of a page within a website. All of these combined (without spaces) enable users to locate a web page. Here’s an example of a URL:

https://www.mailgun.com

Brands use URL links in their email calls-to-action (CTAs) to encourage recipients to click through to websites. At Mailgun, we use a Uniform Resource Identifier (URI) with REST API calls to locate specific resources within email-sending infrastructure. URIs often look like URLs and are used to create webhooks or send an HTTP request via the API.
