Send Form Data Between WordPress Sites (REST API + JetEngine Tutorial)

JetEngine REST API allows you to send form submissions from one WordPress site to another and store data centrally using Custom Content Types (CCT) — no third-party integrations required. In this tutorial, you'll build a centralized participant database on a main site and connect it with an auxiliary site using JetFormBuilder POST requests. This setup works for event registrations, multi-site directories, and any cross-site data collection workflow. This is Part 1 of the JetEngine REST API series. Part 2 covers GET requests (displaying data from a central site). ✅ What you'll learn: • How to create a Participants database with JetEngine CCT • How to register a REST API endpoint for CCT on the main site • How to match form fields with CCT meta fields in JetFormBuilder • How to send form data via POST request to an external site • How to handle media fields using URLs • How to secure requests with Application Passwords ------------- ► TIMESTAMPS 00:00 Use Case 1 — Sending Data via POST Request 00:44 Setting Up CCT for Participants on the Central Site --------------- ► Get JetEngine: https://out.crocoblock.com/4tyEljO ► Get JetFormBuilder: https://out.crocoblock.com/4sSpUH3 ► Choose Crocoblock subscription: https://out.crocoblock.com/4sW7rtr ► REST API Feature Page https://crocoblock.com/features/restapi/ 📄 How to Add and Edit CCT Items Remotely via REST API: https://crocoblock.com/knowledge-base/jetengine/jetengine-how-to-add-and-edit-cct-items-remotely-using-rest-api/ 📌 More JetEngine REST API tutorials: https://www.youtube.com/playlist?list=PL26jaHWVtLFxPww3adEDcOIVwQST7hpFt ------------- #JetEngine #WordPressRESTAPI #Crocoblock #JetFormBuilder #MultiSiteWordPress Have questions about sending data between WordPress sites via REST API?
