====== BASE64_ENCODE (Expression Function) ======

===== Purpose =====
The **Base64 Encode** function (BASE64_ENCODE) takes the input of a field value and encodes it using base64. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies. Base64 encoded data takes about 33% more space than the original data. This function is most commonly used when communicating with a third party system that receives values that are base64 encoded.

==== Field Value ====

Allowed Inputs: [[Field|field]] value

The builder can enter one field value. The builder should use the [[Query Builder]] to choose a field that contains a value. 

===== Output =====

The output of the **Base64 Encode** function is a encoded string comprised of the value from a field.

===== Example =====

BASE64_ENCODE("WorkXpress") returns V29ya1hwcmVzcw==
