PostCaster publishes WordPress posts to Bluesky and Mastodon when a post goes live. It supports both site-wide accounts and personal author accounts, with previews, test posts, and per-post overrides on the post edit screen.
This plugin is intended for editorial sites that want social posting to stay close to the WordPress publishing workflow.
Key capabilities:
<ul>
<li>Publish automatically when a post moves from unpublished to <code>publish</code></li>
<li>Use site-wide accounts in <code>PostCaster > Global socials</code></li>
<li>Let authors use their own accounts in <code>PostCaster > My socials</code></li>
<li>Preview the exact text before publishing</li>
<li>Override the text per article</li>
<li>Choose featured-image behavior per network</li>
<li>Re-publish manually from the post edit screen when needed</li>
</ul>
Quick start:
<ol>
<li>Activate the plugin.</li>
<li>Enable PostCaster in <code>PostCaster > Settings</code>.</li>
<li>Choose which post types may be published automatically.</li>
<li>Configure one or more site-wide accounts in <code>PostCaster > Global socials</code>.</li>
<li>Send a test post for each configured network.</li>
<li>Publish a test article and confirm the result on the target network.</li>
</ol>
Supported networks:
<ul>
<li>Bluesky</li>
<li>
Mastodon 
Permissions and publishing model:
</li>
<li>
Editors and administrators can publish through configured global accounts.
</li>
<li>Authors can publish through their own personal accounts when personal publishing is enabled for them.</li>
<li>A user who has access to both global and personal targets can choose which targets to use during manual publishing.</li>
<li>If Co-Authors Plus is active, linked co-authors are also recognized for personal publishing.</li>
</ul>
Templates and previews:
<ul>
<li>The default message template is based on post title and URL.</li>
<li>You can set a general template, network-specific templates, and post-specific overrides.</li>
<li>The post edit screen shows previews for the currently available publish targets.</li>
<li>If the final message is still too long for a network, PostCaster skips that target and stores an error on the article.</li>
</ul>
For template details and examples, see <code>docs/templates.md</code> in the plugin repository.
Troubleshooting highlights:
<ul>
<li>Always use the built-in test-post buttons after changing credentials.</li>
<li>If a network is enabled but not posting, first check credentials and article-level errors.</li>
<li>If encrypted credentials can no longer be read, re-save them in <code>Global socials</code> or <code>My socials</code>.</li>
<li>Publishing runs through Action Scheduler in the background; low-traffic sites still benefit from a real server cron job or scheduled task for reliable timing.</li>
</ul>
External services:
PostCaster connects to external social networks only after an administrator or user explicitly configures that network and saves the required credentials.
When configured, PostCaster may send:
<ul>
<li>text rendered from post fields and templates</li>
<li>featured image bytes and alt text</li>
<li>the configured account identifiers required by that network</li>
</ul>
Relevant service documentation and terms:
<ul>
<li>Bluesky developer docs: https://docs.bsky.app/</li>
<li>Bluesky terms: https://bsky.social/about/support/tos</li>
<li>Mastodon API docs: https://docs.joinmastodon.org/api/ 
Privacy note:</li>
</ul>
PostCaster does not send usage analytics or telemetry to the plugin author. Network requests are only made to the configured social networks for test posts and actual publishing.
