Use a REST/JSON API from Talend ETL for the second time / HTTP 596

[Anonymous]

Hello,

with the help of this community I succeed to call my first API "https://restcountries.eu/rest/v2/all" without any parameters.

I am now trying to call an API with parameters to provide ... and authorization from API owner 

On https://developer.airfranceklm.com I asked for a key : 

LE Open Data API: Default

Key: azertyuiopqsdfghjklmwxcv Application MyTalendTest Key: azertyuiopqsdfghjklmwxcvSecret: sdfghzerty Status: active Created: 2 seconds ago

Then, I find API documentation on https://developer.airfranceklm.com/docs/opendata/offers/

see attached "step20.PNG"

then, I implement a tRESTclient with 

URL  "https://api.airfranceklm.com/opendata/offers/reference-data"

GET

JSON

see attached "step21.PNG"

I have an error message

There is more information in 

https://developer.airfranceklm.com/developer_boot_camp

but I do not understand how to manipulate all these parameters ...

I adjusted some parameters following https://developer.airfranceklm.com/io-docs

but I know have error HTTP 403

I found my error in the tREST ... most of API parameters have to be specified in the tab "Advanced Parameters" (header) and not in the first page "Simple Parameters" ...
