Fetch and process information for user Identification

Fetch Cookie

Retrieves data from browser cookies.

For example, if your application stores user id in the user_id cookie, enter user_id as the Key of the cookie from where you want to pull the value.

Fetch Element Attribute

Retrieves data from attributes of HTML elements. Based on your requirements, choose a Selector Type (CSS or jQuery), enter Selector Value, Index, and Attribute Name. For example, a Save button on the Salesforce Lightning page has the following Selector Type and Selector Values:

Consider that you have a CSS selector called user-id that contains all user id data. From the selector, you want to find each users’ unique id that is stored as data-userid at the 4th index position in the user-id attribute. Set Selector Type as CSS, Selector Value as data-userid, Index as 4, and Attribute Name as user-id.

Fetch from Local Storage

Retrieves data stored in the browser's local storage. In the Key section, enter the value you want to retrieve from local storage. For example, if your application stores user role data in the local storage as user-role, enter user-role as the Key from where you want to pull the value.

Fetch from Session Storage

Retrieves data stored in the browser's session storage, which is similar to local storage, but the data is stored for the duration of the browser session. In the Key section, enter the value you want to retrieve from the session storage. For example, if your application stores session usage data in the local storage as section-count, enter session-count as the Key from where you want to pull the value.

Fetch from URL

Retrieves information directly from the URL. For example, if your URL is https://whatfix.com/user/123, Whatfix retrieves the entire URL.

Fetch from URL Hostname

Retrieves the hostname from the URL. For example, for the URL https://subdomain.whatfix.com/path, Whatfix retrieves subdomain.whatfix.com.

Fetch from URL Hash

Retrieves data from the URL hash. For example, if your URL is https://whatfix.com/page#section1, Whatfix retrieves section1 from the URL hash.

Fetch from URL Path

Retrieves information from the URL path. For example, for the URL https://whatfix.com/user/123, Whatfix retrieves /user/123 from the URL path.  

Fetch from URL Parameter

Retrieves data from a specific parameter in the URL. For example, if your URL is https://example.com/page?param1=value1, and Whatfix can retrieve the value associated with the key param1 (i.e., value1).

Return Value of Function

Enables the execution of a custom function, and the return value is used as the identification value. In the Function Name section, enter the JavaScript function whose return value you want. For example, you can have a JavaScript function getUserLogin() that returns a true or false value based on whether the user is logged in.

Window Variable

Retrieves data from a variable stored as a Window Variable. In the Key section, enter the name of the Window Variable.

Join

Concatenates multiple strings into a single string.

For example, if you want to add a specific string before the fetcher output:

• Fetcher Output (String): John,Doe,john.doe@whatfix.com

• Sequence Configuration:

  • String 'a': whatfix_user_

  • String 'b': Output of fetcher

• Result: whatfix_user_John,Doe,john.doe@whatfix.com

Split

Divides a string into an array of substrings based on a specified delimiter. You can also use the Index to specify which part of the split result to select.

For example, you want to extract only the email address from a long string, user_profile_data:

• Fetcher Output (String): John,Doe,john.doe@whatfix.com

• Sequence Configuration:

  • Select String: Output of fetcher

  • Delimeter: ,

  • Index: 2 (to get the email)

• Result: john.doe@whatfix.com

Substring

Extracts a portion of a string based on the specified start and end positions.

For example, you want to extract only the first 4 letters of the user name from a long string, user_profile_data:

• Fetcher Output (String): John,Doe,john.doe@whatfix.com

• Sequence Configuration:

  • Select String: Output of fetcher

  • Start Index: 0

  • End Index: 4

• Result: John

To Lowercase

Converts all characters in a string to lowercase.

For example, you want to convert the entire output to lowercase:

• Fetcher Output (String): John,Doe,john.doe@whatfix.com

• Sequence Configuration:

  • Select String: Output of fetcher

• Result: john,doe,john.doe@whatfix.com

Trim

Removes leading and trailing whitespaces from a string.

For example, you want to remove any extra space preceding user_profile_data:

• Fetcher Output (String): John,Doe,john.doe@whatfix.com

• Sequence Configuration:

  • Select String: Output of fetcher

• Result: John,Doe,john.doe@whatfix.com
