Mastodon

Communication Instance URL and access token Windmill docs

Post and read statuses on a Mastodon instance from any Windmill script, flow or app.

Set up in 2 steps

In Mastodon, open Preferences, then Development, and create a new application with the scopes you need. Copy its access token.

Open Resources, add a resource of type mastodon, and fill baseUrl with your instance and token.

Building blocks, if none of the projects above fit. Fork one, run it, or call it as a step inside your own flow.

The shape of the credential every script on this page expects.

Field	Type	Required	What it is
baseUrl	string	Yes	The URL of the Mastodon instance, like "https://mastodon.example.com".
token	string	No	An access token to act as a logged-in user. Leave this empty, if you want to perform unauthenticated requests.

Do I need a token to read?

Not always — public timelines answer unauthenticated requests. Posting always needs one.

Is my token stored on the hub?

Never. It lives only in your own Windmill workspace, encrypted at rest.
