Get contact details for a single LinkedIn profile. Requesting real-time work_emails via email_type=work may increase the response time. This endpoint does not provide real-time verified work_email by default. If you need it in the response, you must pass the additional argument: email_type.

--header "authorization: basic" \
--header "token: <YOUR_API_TOKEN>"

    "work_email": [

    "github":[
      "github_name"
    ]
  }
}

{
  "status_code": 404,
  "message": "Not Found"
}

HTTP Request

GET https://api.contactout.com/v1/people/linkedin?{profile=&include_phone=}

Query Parameters

Parameter	Type	Description
profile	profile: (string, URL encoded, required)	The fully formed URL of the LinkedIn profile. URL must begin with `http` and must contain `linkedin.com/in/` or `linkedin.com/pub/`
include_phone	boolean, optional, Defaults to false	If set to true, it will include phone information in the response and deduct phone credits.
email_type	string, optional	`email_type="personal"` — Returns only personal emails `email_type="work"` — Returns only work emails `email_type="personal,work"` — Returns both personal and work emails By default, both personal and work emails are returned.

No email_type and email_type="personal,work" is almost the same. The difference is that, without email_type, we don't do the real-time guess + verify. Adding the work param will yield more work email results on average but may increase the response time as real-time verification happens on the email provided.

Response Parameters

Field	Type	Description
status_code	integer	The HTTP status code of the response.
profile	object	An object containing contact details for the LinkedIn profile. `url` - The URL of the LinkedIn profile. `email` - An array of email addresses associated with the profile. `work_email` - An array of work email addresses. `work_email_status` - A dictionary indicating the verification status of work emails. `personal_email` - An array of personal email addresses. `phone` - An array of phone numbers associated with the profile. `github` - An array of GitHub usernames associated with the profile.
