Zware Automatic Social Posts and Login

Publish once, share everywhere. Zware Automatic Social Posts and Login (ZASP) is a plugin that does two things:

1. Auto-posts to social networks the moment you hit Publish — Facebook, Instagram, X (Twitter), Threads, Bluesky, Mastodon, and Truth Social are included in the free version.
2. Adds social login buttons to your WordPress login and register pages so users can sign in with Facebook, Google, Apple, X, Twitch, or Discord in one click.

📢 Social Auto-Posting Connect your accounts once and ZASP handles publishing automatically:

• Facebook Pages — posts with image and link preview via the Meta Graph API.
• Instagram Business/Creator — image posts with automatic aspect-ratio adjustment (4:5, 1:1, 1.91:1). Your original image is never modified — ZASP creates a temporary copy, uploads it, and deletes it immediately.
• X / Twitter — tweets up to 280 characters with optional image, using OAuth 2.0 PKCE with automatic token refresh.
• Threads — posts via the Meta Threads Graph API.
• Bluesky — posts via the AT Protocol using app passwords.
• Mastodon — posts to any Mastodon instance with automatic app registration.
• Truth Social — posts via the Mastodon-compatible Truth Social API.

Per-post share controls — the post editor includes a ZASP panel where you can share to each connected network individually and see the last share status per network. Stable token storage — access tokens are stored encrypted in a dedicated database table using libsodium when available. A weekly health check verifies Facebook/Instagram token validity. X tokens auto-refresh before expiry. 🔑 Social Login Let your visitors skip the registration form:

• Facebook — one-click login/register via Facebook OAuth 2.0.
• Google — sign in with Google (OpenID Connect).
• Apple — Sign in with Apple, including first-name/last-name capture on first login.
• X (Twitter) — login via X OAuth 2.0 PKCE.
• Twitch — login via Twitch OAuth 2.0.
• Discord — login via Discord OAuth 2.0.

Three button styles: default (icon + text), rounded, and icon-only. OAuth callbacks use WordPress REST API endpoints (/wp-json/zasp/v1/login/{network}/callback) for compatibility with caching plugins. User creation: Social login creates WordPress user accounts using standard WordPress functions (wp_create_user, wp_set_auth_cookie). New accounts are assigned the role configured in Settings → Login Social (default: Subscriber). Apple identity tokens are verified against Apple's public keys before any account is created or accessed. It is strongly recommended to set the default role to Subscriber and to restrict registration via the site's General Settings if you do not wish to allow open registration. ⭐ ZASP Premium Expand to more platforms with the ZASP Premium add-on (available at zwareonline.com):

• LinkedIn — post to personal profiles and company pages.
• Pinterest — create Pins on any board.
• Auto-Scheduler — queue posts to go out at configured times instead of publishing immediately, checked every 15 minutes.
• Reshare Evergreen — automatically reshare older posts on a daily schedule, with configurable time, day-of-week filters, category/tag filters, and per-post exclusion.
• Missed-schedule recovery — if WordPress misses a scheduled share, ZASP Premium catches and retries it.
• Priority email support.

1.1.1

• Bug fix: Image captions (figcaption, wp-caption, [caption] shortcode) are now stripped from post content when sharing with the "Full content" option. Captions read as disconnected text in social posts because the image they describe is not included.

1.1.0

• Security: Apple Sign In now performs full RS256 cryptographic signature verification against Apple's public JWKs (cached 24 h). Handles key rotation with automatic retry.
• Security: Social login email matching is now gated on provider email verification flags (Google email_verified, Discord verified, Apple email_verified JWT claim). Unverified emails are cleared before account lookup to prevent account takeover.
• Security: New accounts created via social login are always assigned the Subscriber role. The configurable role selector has been removed.
• Security: Social login respects the site's "Anyone can register" setting.
• Bug fix: Instagram publishing now stores the media container_id in post_meta after Step 1 succeeds. Scheduler retries reuse the existing container instead of creating a new one, preventing orphaned containers and intermittent publish failures.
• Bug fix: Instagram container polling extended to 6 polls × 5 s (30 s total) to handle slower Meta image processing. Timeout failures are now retryable without losing the container reference.
• Bug fix: Duplicate auto-shares on scheduled posts fixed. The premium scheduler's publish_future_post hook (which re-queued every scheduled post regardless of whether on_publish had already handled it) has been removed. wp_scheduled_missed is retained for genuinely missed schedules only.
• Bug fix: X (Twitter) token refresh now correctly preserves the stored username label (_label key) when saving the refreshed token. Label was previously lost on every 2-hour refresh cycle, causing the account card to show a numeric ID.
• Bug fix: X token get() no longer filters expired tokens when queried by account_id. The caller needs the refresh_token even after the access_token has expired.
• Bug fix: X token is now saved with expires_in at initial connection, enabling proactive refresh before the API call instead of reactive refresh after a 401.
• Bug fix: X publish() now performs a proactive token refresh if the access_token expires within 5 minutes, eliminating the 401 → refresh → retry round trip in normal operation.
• Bug fix: X has_valid() now considers any stored row as connected (expired or not), preventing false "Conectar" state when the token is merely stale but refreshable.
• Bug fix: X refresh failure on HTTP 400/401/403 or invalid_grant now deletes the stored token so the card correctly shows "Conectar" instead of a broken connected state.
• Bug fix: Facebook profile picture URLs are now stored as stable Graph API redirect URLs (graph.facebook.com/{id}/picture?type=large) instead of expiring CDN URLs.
• Bug fix: Instagram profile picture is now fetched and stored at connect time.
• Bug fix: wp_localize_script for the post editor metabox now includes refresh_nonce, fixing the auto-refresh after publish (the AJAX call was silently rejected because the nonce was undefined).
• Bug fix: Metabox auto-refresh after publish no longer checks isDirty, which was always true during a first-time Publish and prevented the refresh from ever firing.
• Bug fix: Delete queue item handler replaced sanitize_key() with sanitize_text_field()
• regex validation to preserve dots in uniqid() keys (sanitize_key was stripping dots, making the key not match the stored queue entry).
• Bug fix: Instagram OAuth state now uses zasp_create_oauth_state() (HMAC-signed) instead of a random UUID transient, fixing a state mismatch that made Instagram callbacks fail.
• Bug fix: Token Store get() no longer excludes expired tokens when queried by specific account_id; the ORDER BY in the no-account_id path now prefers non-expired rows but falls back to the most recently updated row.
• Improvement: Weekday selector added to Evergreen Republish settings (Programador tab). The reshare cron runs daily but only queues posts on selected days.
• Improvement: Social login page now shows the exact Social Login buttons rendered by ZASP.
