Use a REST API: Difference between revisions
→{{header|Phix}}
(→{{header|Go}}: Added second version which allows for creating events.) |
|||
Line 568:

})</lang>
=={{header|Phix}}==
Uses eventzillaapi.net instead of meetup.com, since unlike the latter it can be done for free.
Unfortunately the API (V2) does not support creating events, so instead this shows how to use
a post method to toggle sales (but see note below).

Note that toggling sales off makes the (manually created) event invisible to the API, even without

it back on. Also as shown omitting said filter changes the field name on the returned results...
