HOW TO ADD A LISTING IN THE BODY OF THE REST POST CONNECTOR x-www-form-urlencoded"

[wdsuarez]

Hi, I need to add a plant_id parameter to the body of the REST post connector. However, there are 35 IDs, and I don't know how to use the "Content-Type" type "application/x-www-form-urlencoded". If I only add one, the connection is successful. I tried plant_id=1, 2, 3,..., 35
;
plant_id=1&plant_id=2&idplant_id=3
;
plant_id[]=1&plant_id[]=2&idplant_id[]=3
and I get an HTTP 500 error.
