TalendStudio (onPrem) - HttpClient - Variables

[DerTim]

Hi,

we are currently tying to figure out how to use the HttpClient component with variables within the json body.

Following the documentation we tried every possible combination of:

• "{.input.job}"
• "{input.job}"
• "{stats_out.input.job}"
• "{stats_out.job}"
• "${stats_out.job}"
• "${.input.job}"
• And every other possible combination we could think of

(stats_out is hereby the name of the flow comming into the HttpClient and job is the column we want to access)

Unfortunatly we are unable to access the data no matter which combination we try. Can someone please explain how to access it?

Hello,

Did you define the var in the '"input" schema ?

Kind regards

Hi Denis,

yes I did:

but no matter what I try it will not be resolved within the JSON body:

Thank you and BR,

Hello Denis,

the Talend Studio we are running is currently on "Version: 8 - Build id: 20250730_0900-patch".

So it seems the issues actually was the escaping of the quotes within the JSON body payload.

Here an example how it worked now for us, in case it is helpful for someone else:
