About this plugin
The WAC POST plugin provides a robust integration between the WeAreContent platform and WordPress sites. It registers two specialized REST API endpoints designed for secure, high-performance content delivery.
These endpoints are strictly protected by a three-layer security model:
1. IP Whitelisting: Access is only granted to authorized IP addresses (local and remote dynamic lists).
2. Application Key: Every request must include a valid X-WACPO-App-Key header, compared using a timing-safe check.
3. Author Capability Check: The configured Default Content Author must have permission to publish posts, verified server-side on every request.
No WordPress username, password, or native Application Password is required to authorize the connection. Content received through the API is attributed to the Administrator or Editor selected in Default Content Author.
Security design note (v4.2.0)
Earlier versions additionally required a native WordPress Application Password tied to a specific user account. That requirement has been intentionally removed: it did not add meaningful security on top of the Application Key, but it forced every site owner to create a WordPress user and generate an application password by hand, which was the leading cause of failed/abandoned setups.
The security boundary has not weakened — it moved from “a WordPress user session plus a key” to “two independent, site-owner-controlled secrets that must both match” (Application Key + IP address), plus a real server-side capability check against the configured Default Content Author (fails closed if that user cannot publish posts).
Author attribution, which used to be inferred implicitly from the WordPress user session, is now an explicit, admin-only setting that can only ever resolve to a real local user, never to caller-supplied data.
Available Endpoints:
* POST /wp-json/wac/v2/create-and-seo-post: Create new posts including featured images, secondary media, and full SEO metadata.
* POST /wp-json/wac/v2/postsys: Update SEO metadata and keywords for existing posts.
* GET /wp-json/wac/v2/ping: Lightweight, read-only connectivity check to verify the Application Key and see the configured default author, without creating any content.
