Configuration:
Options:
host - the url of a mastodon api compatible server(for example: https://mastodon.example/)
token - Access token obtained by authenticating the user. Needs to have access to at least the read:accounts and write:accounts
In order to obtain an access token you can either copy it from for example a browser cookie set by logging in with another client(not recommended, but simpler and easier) or registering an app and asking a client for authorization
First register an application by doing
```
curl -X POST \
-F 'client_name=Pronoun-o-matic' \
-F 'redirect_uris=urn:ietf:wg:oauth:2.0:oob' \
-F 'scopes=read:accounts write:accounts' \
https://mastodon.example/api/v1/apps
```
That should return a json object with a client_id and a client_secret values.
Open an url in your browser:
```
https://mastodon.example/oauth/authorize
?client_id=CLIENT_ID
&scope=read:accounts+write:accounts
&redirect_uri=urn:ietf:wg:oauth:2.0:oob
&response_type=code
```
You should recieve a client secret which you can use get the access token. Simply place them in a curl command like:
```
curl -X POST \
-F 'client_id=your_client_id_here' \
-F 'client_secret=your_client_secret_here' \
-F 'redirect_uri=urn:ietf:wg:oauth:2.0:oob' \
-F 'grant_type=client_credentials' \
https://mastodon.example/oauth/token
```
