## Available libraries

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

___

## 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 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](https://tools.ietf.org/html/rfc5988) for more information.

### Errors

If the request you make doesn't go through, Mastodon will usually respond with an [Error](#error).
