Hello,
Attempting to make a Zap that pulls leads from Facebook Ad lead and sends the data to register member to a BigMarker event.
Unfortunately, on the Bigmarker action, the only fields available are Conference, member first name, member last name, and member email.
There are several more required fields for that event, but they never show up in the Zapier action.
I tried selecting several different events (“conferences”) and still, only those fields appear. How can I get all fields to appear?
Hi
Try clicking the refresh icon to see if that will cause those other fields to appear.
Otherwise, the BigMarker API would have to be used: https://docs.bigmarker.com/
Resources for using app APIs in Zaps:
Hi there, 
I did some checking and found that we have a feature request open for the Register Member to an Event action to support additional fields (such as Company, Company Size, Job Title, Country, State, Phone, and custom fields). So I’ve added your vote to that request, which helps increase its priority. While we can’t guarantee when the developers of the BigMarker app will get that request sorted by, we’ll be sure to send you an email notification when they do!
In the meantime, Troy’s suggestion of connecting to BigMarker’s API would be your best option for now. If you use a Webhooks by Zapier app action, you could send a PUT request to their Register a User to a Conference endpoint to register someone for an event. Webhooks are a bit more advanced so if you’re not familiar with using them in Zaps I’d recommend checking out our Send webhooks in Zaps to learn more.
Let us know if you run into any trouble in setting up that up—happy to help if you get stuck at all!
