Create a Lead and Activity

Lets you create a new lead and post an activity on the lead at the same time.

  • You can use the “SearchBy” parameter to specify a parameter to find the lead by (e.g., email address, phone number). If a lead exists with the specified value, it will be updated with any new lead attributes and activity details you pass.
  • If a lead doesn’t exist based on the “SearchBy” parameter, a new lead will be created in your account.
  • You have to pass the activity event code in the “ActivityEvent” parameter. You can also add values to custom activity fields by specifying the schema name (mx_Custom_1, mx_Custom_2, etc.)
  • In order to get the list of all activity event codes, see Get List of Activity Types.
