Acquisition isn't one of the fields in the field export. How to set aquisition program when using Munchkin.munchkinFunction('associateLead', ... Thanks ~

You can't set the Acquisition Program directly. Send a custom field and then set the AP in a Flow step.I would also recommend using the Forms 2.0 API to submit the form, rather than the Munchkin API, even if you are using a totally custom form. That'll give you an actual Filled Out Form event and will supply the URL that hosts the form, so you can take more conditional actions without having to create extra custom fields.
