Rest with parameter in request header

[PeterS]

Please see attached screenshots. I am trying to make a Rest request with a parameterised Header Value.

Is this possible? It appears that this should work but when I add the parameter the GET returns no records. If I simply enter the correct value (without parametrising) it returns the expected data.

I have just noticed that the second screenshot states that the Parameter is in a Query (this is an error). I have actually had the setting at Header and this failed.

Thanks for your help.

Peter

Hi @PeterS,

Can you post the generated code for this method in the service class?

Please find below code in StaffologyDataHttpHandler.cs and StaffologyDataService.cs. To get around this problem I have set up a static class to hold the apiKey so it is no longer critical for me.

However I will be grateful to understand a more correct way of achieving this if possible.

Thanks for your help.

Regards

Peter
