Usage Examples

BASH / cURL

Betamax has documentated some example API usage from a [bash script](https://en.wikipedia.org/wiki/Bash_(Unix_shell) employing curl (see his posting).

/usr/bin/curl -u USER:PASS https://YOUR.FRIENDICA.TLD/api/statuses/update.xml -d source="some source id" -d status="the status you want to post"

Python

The RSStoFriedika code can be used as an example of how to use the API with python. The lines for posting are located at line 21 and following.

def tweet(server, message, group_allow=None):
    url = server + '/api/statuses/update'
    urllib2.urlopen(url, urllib.urlencode({'status': message,'group_allow[]':group_allow}, doseq=True))

There is also a module for python 3 for using the API.
