As of 1 May 2018, we will no longer support these legacy SOAP-based GTM APIs:
They have been replaced by these REST-based OPEN APIs:
- Traffic Management <https://developer.akamai.com/api/luna/config-gtm/overview.html>
- Global Traffic Management Reporting API <https://developer.akamai.com/api/luna/gtm-api/overview.html>
which are available now.
If you have any questions about this, please post them to the Akamai Developer Community <https://community.akamai.com/community/developer>.
