HTTP Header
The HTTP From request header includes an email address associated with an administrator responsible for the automated user agent.
If you operate a robotic user agent, such as a web crawler, it is essential to include the From header in your requests. This allows administrators or site operators to contact you if issues arise, like excessive, unwanted, or invalid request activity from your bot.
Syntax
The syntax for sending an HTTP request with an email generally involves specifying the email address in a format similar to the example below:
From: <email>
Directives
<email>
A machine-usable email address.

From: [email protected]How to Modify Header using Requestly
Requestly is a powerful Chrome extension that allows you to modify HTTP headers, including the From header. This can help you test how your server handles different sender information or troubleshoot authentication and privacy settings related to the From header. Steps to Modify the From Header:
- Install and open the Requestly Chrome extension. You can find it on the Chrome Web Store.
- Create a new rule: Click on “Create Rule” and choose “Modify Headers” from the list of available rule types.
- Add a new header modification:
- Under “Action”, select “Add” or “Override”.
- In the “Header Name” field, enter From.
- In the “Header Value” field, enter the desired email address or identifier (e.g., [email protected]).
- Set the URL condition: Specify the URL or pattern where this header change should apply (e.g., https://your-api.com/*).
- Save the rule.
Once set up, Requestly will inject the From: [email protected] header into all matching requests, allowing you to test how your server or application handles requests based on the sender’s identity. Modifying the From header is useful when you want to simulate requests from different users or sources without changing your actual client, helping in debugging authentication or customizing server responses.
