Part 2 of this.

I'm trying to test a REST service, mentioned above, and have to send an api-key header. However the code
            Get Value of oCreds to sToken
            Get AddHeader of oHttp ('api-key:' * sToken) to iOK
appends a colon ':' to the token. The REST service have confirmed that's what makes my token fail.

Damned if I can see where it comes from, and AddHeader seems to be in the runtime so is hidden.

The token is just a 40-character string

but Fiddler reveals that what get sent is
api-key: xxxx0D4A5C23411D88B5634B5A603076:

Any ideas?
