The response has much less details and different format.
The only thing you can get from it is the name.
Not tags or other staff.
See the next example:
{7 items
“gender”:NULL
“nationalFormat”:“077-276-4463”
“facebook”:NULL
“e164Format”:"+972772764463"
“name”:“תיקון נפטרים ספאם”
“countryCode”:“IL”
“email”:NULL
}

What response did you get and what was missing?

Something to keep in mind - the results depends on Truecaller database and they might not have all the data about every number - such as email or social media 😃
