HeadlessNext Connector Pro Documentation

HeadlessNext Connector Pro is the paid tier of the free HeadlessNext Connector plugin — production-grade revalidation credentialing for any headless WordPress setup you’ve already built, whether or not it uses HeadlessCore or the HeadlessNext theme.

Requirements

• The free HeadlessNext Connector plugin, installed and active
• A HeadlessNext Connector Pro license key (hnp1. prefix)

What Pro adds over the free Connector

• HMAC-signed webhooks for revalidation requests, instead of a bare

shared secret in a URL — your frontend can cryptographically verify every request actually came from your WordPress site, not just that it knows a string.

• A delivery log, so you can see exactly what fired, when, and

whether it succeeded, instead of guessing why a page didn’t update.

• Multi-site license seats, for agencies running the connector

across several client sites under one license, instead of buying a separate license per site.

Step-by-step installation

Step 1 — Install the free Connector first

Pro is an add-on, not a standalone plugin. If you haven’t already, install and activate the free HeadlessNext Connector (see its documentation) and configure your Frontend URL and Revalidation Path.

Step 2 — Purchase Connector Pro

Connector Pro is sold separately from HeadlessCore, via Stripe checkout. Payment mints an hnp1.-prefixed license key, delivered by email and shown on the confirmation page.

Step 3 — Install the Pro plugin

1. In wp-admin: Plugins → Add New → Upload Plugin.
2. Select the Connector Pro plugin ZIP, click Install Now, then

Activate.

Step 4 — Activate your license

Go to Settings → HeadlessNext Connector → License Key and paste your hnp1. key. Once activated, the plugin switches from the free plain-secret revalidation to HMAC-signed requests automatically.

Step 5 — Verify signed delivery

Publish or update a post, then check the delivery log in the same settings screen — you should see the request logged with its timestamp and delivery status. If a request fails, the log entry shows why (unreachable frontend, signature mismatch, timeout).

Multi-site seats

If your license includes multiple seats, install and activate Connector Pro on each client site and paste the same license key — each activation consumes one seat. Seat usage is visible on the licensing screen.

Purchasing

Connector Pro is sold separately from HeadlessCore, via Stripe checkout. Your license key is minted and delivered automatically after payment — no manual issuance or waiting.

Troubleshooting

• License key rejected — confirm you’re pasting the full key

including the hnp1. prefix.

• Webhooks not firing — confirm the free Connector’s **Frontend

URL and Revalidation Path** are still set; Pro layers on top of those, it doesn’t replace them.

• Delivery log shows failures — check that your frontend’s

revalidation endpoint is reachable from your WordPress server (not blocked by a firewall) and is verifying the HMAC signature correctly.
