# abstract class OAuth2::AccessToken

- OAuth2::AccessToken
- Reference
- Object

## Overview

Base class for the two possible access tokens: Bearer and Mac.

Use `#authenticate` to authenticate an `HTTP::Client`.

## Direct Known Subclasses

- OAuth2::AccessToken::Bearer
- OAuth2::AccessToken::Mac

## Defined in:

## Constructors

- .new(access_token : String, expires_in : Int?, refresh_token : String? = nil, scope : String? = nil, extra = nil)
- .new(pull : JSON::PullParser)

## Instance Method Summary

- #access_token : String
- #access_token=(access_token : String)
- #authenticate(request : HTTP::Request, tls)
- #authenticate(client : HTTP::Client)
- #expires_in : Int64?
- #expires_in=(expires_in : Int64?)
- #extra : Hash(String, String)?

  JSON key-value pairs that are outside of the OAuth2 spec are stored in this property in case they are needed.

- #extra=(extra : Hash(String, String)?)

  JSON key-value pairs that are outside of the OAuth2 spec are stored in this property in case they are needed.

- #refresh_token : String?

JSON key-value pairs that are outside of the OAuth2 spec are stored in this property in case they are needed. Their value is the raw JSON string found in the JSON value (with possible changes in the string format, but preserving JSON semantic). For example if the value was `[1, 2, 3]` then the value in this hash will be the string "[1,2,3]".
