How do I make a script send an embed to discord?

I know the title may make this look simple but I am very confused. For the past half hour I have been trying to figure out how I send an embed to discord using http service.

local data = {
							["content"] = "embed!",
							["embeds"] = {
								{
									["title"] = "a",
									["description"] = "a",
									["type"] = "rich",
									["color"] = tonumber(0x00ff00),
									["fields"] = {
										{
											["name"] = "__A__",
											["value"] = "a",
											["inline"] = true,
										},
										{
											["name"] = "__B__",
											["value"] = "b",
											["inline"] = true,
										},
									},
								},
							},
						};
						data = h:JSONEncode(data);
						repeat
							local s,e = pcall(function()
								h:PostAsync(wh, data);
							end);
							if (not s) then warn(e) end;
							wait();
						until s;

That's my code but if I comment out the embed part it says "embed!" in discord. Ignore all of the ; characters its just a coding habit.

My issue if you still haven't figured out is that the embed wont send.
