  1. Developing in C#
  2. Invocation context

Invocation context

    Invocation context is an object that is optionally accepted by the request handler in case you use the YcFunction interface model. The object type is Yandex.Cloud.Functions.Context. It provides properties for getting more information about the function version:

    • FunctionId: Returns the string ID of the function.
    • FunctionVersion: Returns the string ID of the function version.
    • MemoryLimitInMB: Returns the amount of memory specified when creating the version, MB.
    • RequestId: Returns the ID of the request being handled.
    • TokenJson: Returns the parameters required for authentication in the Yandex.Cloud API.
