Core Forms 4.1.0-beta2 | Gatilab Products

External sites (Astro, Next.js, plain HTML, anywhere) can now render and submit Core Forms over REST.

New endpoints under /wp-json/core-forms/v1:
GET /forms/{id} — schema (HTML + structured fields)
POST /forms/{id}/submit — runs the same validation/captcha/action pipeline as on-site submissions
GET /embed.js — drop-in vanilla JS widget
Site-wide API key (Settings → Headless) gates submissions; per-form Headless tab toggles exposure on/off and shows copy-paste snippets (widget, native fetch, cURL) pre-filled with the actual key.
Reveal/generate/copy controls on the API key field, status banners on the per-form tab.
CORS reflected per-origin; captcha is force-recommended since cross-origin submits can't use WP nonces.

Hosted-checkout handoff via FluentCart's own checkout — works on free + Pro, one-time + subscriptions.

New FluentCart payment gateway slots into the existing payments orchestrator alongside Stripe/PayPal/Razorpay/Polar.
Per-form Variation ID picker with live preview (title, price, payment type, link to FluentCart).
Listens to fluent_cart/order_paid_done to mark submissions paid and fire the post-payment action loop. order_status_changed_to_refunded syncs refunds back.
Pricing/currency come from the FluentCart variation — the form's Pricing fields are bypassed when this provider is selected.
Subscription variations work transparently on FluentCart Pro (FluentCart owns the recurring billing).

Per-form Payment tab sections converted to native <details>/<summary> accordions matching the global Payments gateway list.
New Headless tab in the form editor with status banners, monospace code blocks, floating copy buttons, color-coded HTTP method tags.
Same-site gateways (FluentCart) skip the irrelevant Webhook URL row in global settings and explain why no credentials are needed.
