Add header element in cHttp in Route

Hello,

I have a scenerio. I am retreiving fingerprints of certificate in C processor component. After getting the fingerprints I want to put the fingerprints as a header in cHttp component as it should call an existing endpoint and in response I should get a token. In Advance settings of cHttp component I tried it as key = fingerprint, value= ${header.fingerprint but it did not get fingerprint. it is printed it as a string on console. It only works if I give a constant value of fingerprint manually. e.g key = fingerprint, value = 841753ad7699018c434c35dba51. So my question is how can I get the value of fingerprint in cHttp component ? any help would be appreciated.and the condition is

you have to store your value (i will suppose its name is fingerprint ) in a gloabal varaible .

to do this you have 2 options either use a tjava ( globalMap.put("fingerprint "), row1.fingerprint )

and then get the global variable using this globalMap.get("fingerprint ")

Then in cHttp_1 pass the value globalMap.get("fingerprint ")

or , try using a tsetglobalvariable component see documentation here https://help.talend.com/r/oApq_IF_zN1NFA_hv2494Q/QZyYO6k~Q8rZJHIwR5J16Q

Then as in first option pass the global variable globalMap.get("fingerprint ")

Or pass your variable with a context varaible .

Thanks

Where are you originally setting the value of ${header.fingerprint}? Is this being set in the cProcessor? Because if this header exists, it should be being passed to the service you are calling. You are overwriting it with a constant value in the screenshot above.
