There are two ways to validate an HTTP request on the platform. The
first is called “status code,” where we check if the response status
code belongs to the 200 family (for example, 200, 201, 204, etc.),
indicating a successful response.

The second way is by using “String Validation,” which can also accept
a Regular Expression. Regular Expressions are patterns of characters
that associate character sequences in text. We can use regular
expressions to extract or replace portions of text( such as an email
address or image link in an HTML page), modify the text format, or
remove invalid characters. This way, you can perform more complex checks
on HTTP response data.This allows you to perform more detailed and
precise validations, such as the example below.

If your API returns:

{

status: 1,

name: xyz

}

Any non-zero status result is considered valid, so you would define as:

String Validation:

status: [^0]

For more details on how to use Regular Expressions you can check out the GoLang documentation.
