The HTTP request received by this HTTP server was an HTTP GET request. This API expects an HTTP POST request to perform the base64 operations.
The default action is to encode and no special parameters are required. You may include the additional path '/encode' to ensure encoding. (Ex. /api/base64/encode)
To decode, add '/decode' to the URL path (Ex. '/api/base64/decode') or include the header key 'action' with the value 'decode'.
If you prefer a text box to paste into, the form below will encode/decode base64.
