So from the notes it looks like the join meeting API will only accept POST requests starting early next year.
I'm scratching my head trying to think of other ways to maintain the functionality.
Greeetings! I am unfamiliar with Moodle and the plugin that you've written for it. Most programming languages, however, allow a person to build and send a POST request, e.g. PHP's http_post_fields() function.
Michael, That wouldn't be terribly useful, as now the server will have joined a meeting, not the user using the website.
For a host account you can also check out GethosturlMeeting
Thanks, I'll have to poke them some more. The API docs you reference show them returning soon to be invalid URLs with the PW parameter.
