Overview

Decodes Base64 information into human-readable text.

Syntax

Base64Decode(1, 2, 3)

Function Properties

Ordinal	Type		Description
1	string	Required	Location of Base64 text, either in variable or data extension field via Lookup() AMPscript function
2	string		.NET-supported character type used in decoding process, such as UTF-8 or UTF-16
3	int		Indicates whether the email send proceeds with incorrectly coded Base64 text. A value of 0 allows the send to proceed if send encounters an error. A value of 1 prevents the send from continuing if send encounters an error. Value defaults to 1.

Usage

%%[
VAR @encodedStr, @decodedStr
SET @encodedStr = Lookup('Base64Info', 'ReceiptData', 'ReceiptKey', 1)
SET @decodedStr = Base64Decode(@encodedStr,'UTF-8')
]%%
The Lookup() function retrieves the Base64 information from the data extension, and the Base64Decode() decodes the Base64 information and assigns that value to the @decodedStr variable in UTF-8 format. If for some reason the value of @encodedStr is incorrect, the 1 at the end of the Base64Decode() function causes the send to fail due to the error.
%%[
VAR @encodedStr, @decodedStr
SET @encodedStr = Lookup('Base64Info', 'ReceiptData', 'ReceiptKey', 0)
SET @decodedStr = Base64Decode(@encodedStr,'UTF-8', 1)
]%%

If the value was 0, the send would continue and the email would contain an empty string instead of the decoded data.
