Thanks once again Dave !
Its very conforting to see that there is people like you in this word always up to help others.
Unfortonattly it didnt work . Only the way i did on my second post creating a ${inner} e ${array} worked for me , but like i sayd before that was a small body and kinda easy to work with. For the other example i have no idea whats going on but nothing works 
even when i try to make the request on the Swagger i get a 500 error. I have no clue what im doing wrong … i’ve tryed what you sayd about changing the data to json also but it didnt worked aswell…
Im smashing this api request for like a week already and i got nowhere.
I’ll leave here a link of the API if there is anyone up to have a look… i’ve find it very usefull for a test but at the same time im not getting anywhere with this:
It’s my first time using robot on a api and i’ve found it very hard to understand to be honest… working direct with websites, xpaths and stuff was so easy but when i got that “test” i’ve learned that i still dosnt know anything about robot. I would love if someone could show me how i could make this work properly since im very noob and cant even make it work from the swagger. Hopefully its just the api that sucks and i might know somenthing. Or not.
Once again im very gratful for you help Dave! that was awesome from you. All the best !
