The set-date HTTP POST function provides a means to set or update an Infusionsoft contact field with a date/time. You can do basic math on these dates, and when used with a date value this is very useful when used in conjunction with Infusionsoft’s “Field Timer” tool in the Campaign Builder.

Field Types

Field Timers enable you to schedule a marketing action based on a date field in the contact record. There are two built-in date fields in contact records, the Anniversary and Birthday. You can also create custom fields using the date field type. Only Date fields will work with field timers, Date/Time fields will not work.
