You can notify Follow Up Boss when certain events occur on your website or system, for example user fills out a registration form on an IDX website, sends an inquiry about a property or submits Contact Us form. This is the only correct way to send leads and their activity to Follow Up Boss from an IDX website, real estate portal, your custom website or any other lead source.
New leads created by POST /v1/events will only trigger action plans if they are of the following types: "Registration", "Seller Inquiry", "Property Inquiry", "General Inquiry" "Visited Open House"
If you receive a 204 response with no response body, this indicates that the lead flow associated with this source has been archived and ignored.
If the account has custom fields defined you can also set these when sending in an event. You can use the customFields endpoint to see which custom fields are available in the current account.
