Request Parameters

Parameter Description

The name of an email template (either system generated or created by you). You can find it under Email Library.


This parameter lets you choose how you want to pass the sender of the email. Depending on the chosen value for this parameter, you will have to pass a corresponding value in the “Sender” parameter.

The “SenderType” can be passed as:

  • UserId
    If you pass this value, the “Sender” parameter must contain the user Id of the sender.


  • “UserEmailAddress”
    If you pass this value, you can simply specify the sender’s email address in the “Sender” parameter.


  • “APICaller”
    If you pass this value, you don’t have to pass any value in the “Sender” parameter. The email address of the person who called the API will automatically be displayed as the sender of the email.


  • “LeadOwner”
    If you pass this value, you don’t have to pass any value in the “Sender” parameter. The lead owner will automatically be displayed as the sender of the email.

Use the required administrator or marketing user email address.


This is the unique ID of a lead’s list. To get this, refer to the Retrieve all Lists API


This parameter allows you to schedule the email for a later date and time. If you don’t pass this value the email will be sent immediately.
Be sure to adhere to the “YYYY-mm-dd HH:mm:ss” format.


The name of your email campaign. For example “Merry Christmas from Example Brand”.


You can pass this value as “true” if you wish to add a footer in your email or as “false” if you don’t.
