Create Leads in Bulk

Lets you create up to 50 leads in a single API call.

Pass as many lead fields (including custom fields) as you want but be sure to pass at least one of these for each lead –

  • FirstName
  • LastName
  • EmailAddress*
  • Phone Number*

* These fields are unique in LeadSquared by default so it’s recommended to pass at least one of them while creating a lead. If you want to change the unique fields of your leads navigate to My Account>Settings>Customization>Lead Fields and click the wheel icon beside a lead field to mark or remove uniqueness.

Note: If you want to create one lead at a time, use the Create Lead API.
