Content-Type : multipart/form-data; boundary=<calculated when request is sent>

[ClementSo]

Hello,

I would like to POST with Download tool a request to update value or insert value.

BEFORE POST
id	libelle	adresse	cp	ville	pays
PA75000	PARIS	1 rue de paris	75000	Paris	FRANCE
MA13000	MARSEILLE	2 rue de marseille	13000	Marseille	FRANCE
AFTER POST
id	libelle	adresse	cp	ville	pays
PA75000	PARIS	1%20rue%20de%20paris	75000	Paris	FRANCE
MA13000	MARSEILLE	2%20rue%20de%20marseille	13000	Marseille	FRANCE

All whitespaces have been replaced by %20.

When i use POSTMAN i d'ont have this returns and the boundary was calculated :

Could you explain to me how I can generate the Boundary with ALteryx?

Thinks
