How to setup Headers and body on REST POST method in Pentaho?

Question

I need to setup headers (Authorization) on the REST Client (Post method) in Pentaho.

I'm passing on the Authorization header as a parameter to the REST Client. Then use that variable inside the Headers field.

But I'm not sure I'm doing it right.

First step, set header on constant.

Second step, using header variable on rest client step

when I use postman passing the same headers, it works very well, like this

this is my ktr

I solved my problem just changing REST CLIENT step by HTTP POST, It works very well.

This damn step rest client just doesn't work when you need send a post request with json body.

In the Field area you select the actual value of the parameter you are entering in the header, in the Name area you type in the actual Type of the parameter.

For example you would feed the Field area with a column in the rows before the step and in the Name area you would type Content-Type

The step would receive

Field -------------------------------------------Name

application/xml;charset=utf-8 ---------- Content-Type

You are trying to push in an entire JSON document in 1 cel correct ? Try separating this into Content-Type, access_token, itau-chave, identificador, as the column names, and their respective values. I have update my answer with an image example. — Cristian Curti, Aug 03 '18 at 16:39
now it returned mal formed url error =( , don't know what to do anymore — luiz kava, Aug 03 '18 at 17:40
If i may, try using another program to emulate the REST calls before automating everything in Pentaho, i use Postman to test and build all REST/API/HTML calls before automating to pentaho. — Cristian Curti, Aug 03 '18 at 18:43
I'm using the postman and it works very well, I'll put the call on my question. — luiz kava, Aug 03 '18 at 18:55
I have added a KTR example for you to try yourself, i ran it and i got error authentication message, which is excpected from generated keys. Simply change the values in the Generate rows step. — Cristian Curti, Aug 03 '18 at 19:33

I think now my problem is in body json, I added my transfom in my question. — luiz kava, Aug 04 '18 at 16:37
