Yes, it works with Postman, I found first solution.
I tested with a text directly like that :
concatenate(“https://kazoo-dev-ed.my.salesforce.com/services/data/v47.0/query?q=SELECT Name,NumberOfMonth_retail__c, KazooRetailPrice__c,RentPrice__c FROM ProductReference__c WHERE Name=”,"'Clean et steam’")
and it works correctly
But now, i would like to use weweb variable but it doesn’t work again
I tried but I need to add ’ ’ around the text.
So I found a workaround, before to put the value into the weweb variable I use Concatenate function like that : concatenate(“'”,VARIABLE,“'”)
And It works
Thanks a lot for your support. For sure I will back soon with a new question
