WebEx URL API stopped working since recent WebEx upgrade

[iancseertech19a]

Since the Cisco/WebEx upgrade of the weekend 10th October our integration with WebEx using the URL API has stopped working.

To host a meeting from our LMS we use an HTTP POST to the following URL:

https://<<sitename>>.webex.com/<<sitename>>/p.php?AT=LI&WID=<<USERNAME>>&PW=<<PASSWORD>>&MU=....

This now returns the following error:  badWebExIDOrPassword

The username and password supplied in the URL are valid - we can login directly to WebEx using the same account

The meeting has been created using the XML API without issue.

Have checked the documentation and recent changes to URL API - one of the recommendations is to use POST if supplying the PW parameter which we are doing.  Has anything else changed to the URL API that would start to cause this?

Any assistance appreciated.

We have a similar Problem with our LMS, but we are starting fresh. But mid last year we tested the interface and it worked fine. All Login data in the LMS is correct. I am not sure how the API adresses the Training Center platform, but the fault message is also stating "wrong ID or Password".
