What bundle.social handles
Keep Mastodon in the same workflow as every other channel
Your open-source community deserves consistent content as much as any brand. Stop treating Mastodon as a manual afterthought and put it in the same calendar.
Workflow
How it works
Connect accounts once, then create and schedule posts with channel-specific fields from one API.
Create an API key
Generate an organization API key in the dashboard and use it with the x-api-key header.
Connect accounts
Connect each social account once. bundle.social keeps the account mapping ready for future posts.
Create or schedule posts
Send one request with the publish date, selected channels, and the fields each platform needs.
Capabilities
Mastodon scheduling with the workflows your team already uses
Mastodon fits into the same scheduling, media, and status workflow as every other channel.
Mastodon in your cross-platform calendar
Plan and schedule Mastodon content alongside Instagram, LinkedIn, X, TikTok, and every other channel without switching between native dashboards.
Channel-specific field control
Mastodon content still uses the options and fields the platform supports. No generic template that loses native capabilities.
Team review and approvals
Marketing teams can draft, review, and approve Mastodon content in the shared calendar before anything publishes.
Media library for campaigns
Upload visuals, videos, and documents once and attach them to Mastodon posts using upload IDs across your content plan.
Post status tracking
See whether each Mastodon post is scheduled, processing, posted, or failed without checking the native platform dashboard.
Analytics where available
Pull Mastodon performance data and import post history for connected accounts where the platform API and permissions allow it.
Developer example
Schedule Mastodon content
Examples use bundle.social's public API shape: API key authentication, a post date, selected social account types, and platform-specific data.
