Get a Lead by Phone Number

Returns a lead’s details (First name, Last name, Email Address, Location, etc.) based on the phone number you pass in the API URL.


  • The API retrieves the lead based on the “Phone” and “Mobile” lead fields only.
  • You can no longer pass the additional parameter searchByOtherField=true in the API URL to search using a lead using a different field. This functionality has been deprecated.

If more than one lead matches the phone number you pass, the API will return the lead with the most recent activity. You can pass the phone number with or without the country-code but don’t include spaces, hyphens or any other character.
