Hello @Williams_Farias,
Welcome to community.
First of all, what you’re seeing here on that Mapping dialog box it’s always shows the first element only, It’s mostly used just to preview how data looks behind that array/collection.
If you want to see that actual data always check for that preview bubble like this.
After the webhooks use Iterator to iterate data and then do the next operation on every particular element within in loop.
P.S.: Always search first, Check Make Academy. If this is helpful, mark it as a solution 
and
