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Publish automatically when a post moves from unpublished to 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.

<h3>External services</h3>
Social Publisher connects to external services only when a site administrator enables a provider, starts an authorization flow, tests a connection, opens a share action, or publishes content to that provider.
The plugin stores the credentials returned by each provider in the WordPress database for the current site. It uses those credentials only to validate the connection and publish content chosen by the administrator. Debug logs are sanitized to avoid storing access tokens or OAuth secrets in clear text.
No data is sent to a social network unless that specific integration is configured and used.
