Available libraries

There are several libraries to interact with the Mastodon API. The list of libraries can be found on the Libraries page.

---

Notes

Parameter types

When an array parameter is mentioned, the Rails convention of specifying array parameters in query strings is meant. For example, a ruby array like foo = [1, 2, 3] should be encoded in the params as foo[]=1&foo[]=2&foo[]=3, with empty square brackets.

When sending binary data, such as files, Mastodon expects clients to use the multipart/form-data MIME type. This applies to media attachments, account avatars and account headers.

Selecting ranges

For most GET operations that return arrays, the query parameters max_id and since_id can be used to specify the range of IDs to return. API methods that return collections of items can return a Link header containing URLs for the next and prev pages. See the Link header RFC for more information.

Errors

If the request you make doesn't go through, Mastodon will usually respond with an Error.
