End of support notice: On May 31, 2026, AWS will end support for AWS Panorama. After May 31, 2026, you will no longer be able to access the AWS Panorama console or AWS Panorama resources. For more information, see AWS Panorama end of support.

Application parameters

Parameters are nodes that have a basic type and can be overridden during deployment. A parameter can have a default value and a decorator, which instructs the application's user how to configure it.

Parameter types

  • string – A string. For example, DEBUG.

  • int32 – An integer. For example, 20

  • float32 – A floating point number. For example, 47.5

  • boolean – true or false.

The following example shows two parameters, a string and a number, which are sent to a code node as inputs.
