Since a couple of days, when I try to log to developers.thomsonreuters.com and head to the APIs, I get:
The page you requested cannot be found: https://developers.thomsonreuters.com/simplesaml/module.php/saml/sp/saml2-acs.php/iam-prod-sp
I can only log to Q&A section
They have fixed this problem.
The Developer Community sub-site keeps being very heavy and slow, but it works.
