Using twilio?

I wonder if anybody can talk me through getting twilio to work ? I have some agent code ( from alexba s blog which uses an imp to send a text when a washing machine is finished ) which works well , but having registered with twilio I can’t make head nor tale of it. I ve emailed Alex via his blog but wonder if anybody on here can shed any light ?
Thanks

The new library class has some instructions for getting started.

You can even try the alternative of twillio. For reference use this link

I be just tried using the twilio library from the link above, filling in the required details and I m still getting an error message. I wonder if anybody else has got this to work from within the imp ide and has had similar problems ?
Thanks
