Setting Authorization Headers in IBM API Connect Test and Monitor

I've recently started exploring the IBM API Connect Test and Monitor tool on IBM Cloud here: -

and was having some fun n' games setting an HTTP Header, using either the basic HTTP Client or the more detailed Test Composer.

My API requires that one send an IAM token, rather than the more Basic Auth of user/password, which is nice :-)

This kept failing with HTTP403 Unauthorized.

Thankfully IBM have a nice active support community on Stack Overflow, so I posted a question here: -

Setting Authorization Headers in IBM API Connect Test and Monitor

and got some rapid feedback from the community.

In essence, I was doing it wrong ....

This is what I needed to do: -

In other words, for the Key/Value Pair (KVP) that comprises the HTTP Header field, I needed to specify Authorization as the key and Bearer XXXXXXXXXXXXXXX as the value ( with a space between the word Bearer and the actual IAM token itself.

So I was holding it wrong .... #Doofus

Apart from the basic HTTP Client, there's also a very spiffing Test Composer, that has the same requirement wrt Authorisation headers: -

For the record, there's also a GitHub project for a native client here: -

with which I've played a wee bit .....

Postman on macOS - Where are my Windows ?

Having used Postman for the past few months, mainly to poke REST APIs, I hit an interesting issue last night, whereby the main Postman window refused to appear even though I'd left it open when I suspended my Mac ( closed the lid ) before leaving the office.

Now, for clarity, at work I use an external Lenovo monitor, attached via USB-C / HDMI ( using the Apple dongle ), which is positioned to the right of the MacBook Pro itself.

When I got home, I plugged in a different AOC monitor, again via USB-C / HDMI ( using a different non-Apple dongle ), again with the MBR on the left of the monitor ( "On your left" ).

Despite stopping/starting Postman multiple times, and fiddling around with the various options available on the View and Window menus, I couldn't get the main window to appear ....

Thankfully, the internet brought me to this ....

Postman opens off screen(s) when display monitors are changed #2833

which said, in part: -

For the moment, if you guys see this, you can reset the app's window settings manually. To do this, you'll need to delete the requester.json file from the app's data directory, this is located:

on macOS: ~/Library/Application\ Support/Postman
on Windows: C:\Users\AppData\Roaming\Postman
on Linux: ~/.config/Postman

and: -

In fact, you also need to delete the window file in the same directory.

Having quit Postman, I dived into Terminal ( because, Terminal ) and did this: -

rm ~/Library/Application\ Support/Postman/storage/requester.json 
rm ~/Library/Application\ Support/Postman/window 

and started Postman again .... c'est voila, here's a Postman window :-)

For the record, I'm using Postman 7.0.9, which is interesting 'cos that post is circa 2017 ....
