| + | ===== Purpose ===== | ||
| + | The **Base64 Decode** function (BASE64_DECODE) takes the input of a field value and decodes 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 send values that are base64 encoded. | ||
