# Find Single Phone

> Find a single phone number from a LinkedIn URL or name and company with the Phone Finder API

<Badge color="green">POST</Badge>

```
https://api.enrow.io/phone/single
```

Run an asynchronous search to find a phone number and the associated country. Authenticate every request with your [API key](/authentication) in the `x-api-key` header.

The search needs to contain either:

* The URL of a person's **LinkedIn profile** (e.g., `https://www.linkedin.com/in/michael-scott/`)
* The combination of individual information: `firstname` + `lastname` + (`company_name` or `company_domain`)

The **LinkedIn URL will always prevail** on the individual information if both are present, as it is the best way to discriminate a single person and avoid homonym-related issues.

## Request Body

**Option 1 (Recommended):**

<ParamField body="linkedin_url" type="string">
  LinkedIn profile URL of the person.

  **Note**: Takes precedence over individual information if both are provided.
</ParamField>

**Option 2:**

<ParamField body="firstname" type="string">
  First name of the person
</ParamField>

<ParamField body="lastname" type="string">
  Last name of the person
</ParamField>

<ParamField body="company_domain" type="string">
  Company domain (e.g., `"dundermifflin.com"`)
</ParamField>

<ParamField body="company_name" type="string">
  Company name (alternative to `company_domain`)
</ParamField>

**Additional:**

<ParamField body="custom" type="string">
  A custom value you can use to reference an internal ID. It will be present in the results.
</ParamField>

<ParamField body="settings" type="object">
  Settings related to this search.

  <Expandable title="settings properties">
    <ParamField body="webhook" type="string">
      A URL that will be notified through an HTTP POST request once the search is finished. See [How Webhooks Work](/how-webhooks-work).
    </ParamField>
  </Expandable>
</ParamField>
