Sample Usage:


DECLARE @CurrentURL nvarchar(MAX)
DECLARE @Response nvarchar(MAX)
DECLARE @StatusCode int
DECLARE @StatusDescription nvarchar(MAX)

EXEC usp_Mailgun_Bounce_Fetch	
		@Profile = 'My Mailgun',
		@emailAddress = 'bob@example.com',
		@CurrentURL = @CurrentURL,
		@Response = @Response OUTPUT, 
		@StatusCode = @StatusCode OUTPUT, 
		@StatusDescription = @StatusDescription OUTPUT

IF @StatusCode >= 400
	EXEC SQLHTTP.net.RaiseHttpError @StatusCode, @StatusDescription, @Response
ELSE
	BEGIN

		DECLARE @X xml
		SET @X = SQLHTTP.net.Json_To_Xml(@Response, '0')

		--The XPath syntax below was easily generated by executing the following commands:
		--EXEC SQLHTTP.net.XQueryHelper @X
		--and then executing: 
		--EXEC SQLHTTP.net.XQueryHelper @X, 'JsonObject'
		
		SELECT T.C.value(N'@address', N'nvarchar(MAX)') AS [address]
		      ,T.C.value(N'@code', N'nvarchar(MAX)') AS [code]
		      ,T.C.value(N'@created_at', N'nvarchar(MAX)') AS [created_at]
		      ,T.C.value(N'@error', N'nvarchar(MAX)') AS [error]
		FROM @X.nodes(N'/JsonObject') T(C)

	END
