Skip to main content
Your script has access to stdout and stderr for writing output. The API also returns the program’s exit code.

​
Write to stdout

The execute code endpoint returns anything your script writes to stdout as the value of the stdout parameter.

​
Write to stderr

The execute code endpoint returns anything your script writes to stderr as the value of the stderr parameter.
