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] can be encoded in the params as foo[]=1&foo[]=2&foo[]=3. Square brackets can be indexed but can also be empty.

When a file parameter is mentioned, a form-encoded upload is expected.

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.
