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
|
|
```
