Attributes

DRY_RUN

(experimental) Validate parameter values and verify that the user or role has permission to invoke the function.

Stability:

experimental

EVENT

(experimental) Invoke the function asynchronously.

Send events that fail multiple times to the function’s dead-letter queue (if it’s configured). The API response only includes a status code.

Stability:

experimental

REQUEST_RESPONE

(experimental) Invoke the function synchronously.

Keep the connection open until the function returns a response or times out. The API response includes the function response and additional data.
