A StepFunctions task to call an AWS service API.

ExampleMetadata:

infused

Example:

# my_bucket: s3.Bucket

get_object = tasks.CallAwsService(self, "GetObject",
    service="s3",
    action="getObject",
    parameters={
        "Bucket": my_bucket.bucket_name,
        "Key": sfn.JsonPath.string_at("$.key")
    },
    iam_resources=[my_bucket.arn_for_objects("*")]
)
Parameters:

  • scope (Construct) –

  • id (str) –

  • action (str) – The API action to call. Use camelCase.

  • iam_resources (Sequence[str]) – The resources for the IAM statement that will be added to the state machine role’s policy to allow the state machine to make the API call. By default the action for this IAM statement will be service:action.

  • service (str) – The AWS service to call.

  • iam_action (Optional[str]) – The action for the IAM statement that will be added to the state machine role’s policy to allow the state machine to make the API call. Use in the case where the IAM action name does not match with the API service/action name, e.g. s3:ListBuckets requires s3:ListAllMyBuckets. Default: - service:action

  • parameters (Optional[Mapping[str, Any]]) – Parameters for the API action call. Use PascalCase for the parameter names. Default: - no parameters

  • comment (Optional[str]) – An optional description for this state. Default: - No comment

  • heartbeat (Optional[Duration]) – Timeout for the heartbeat. Default: - None

  • input_path (Optional[str]) – JSONPath expression to select part of the state to be the input to this state. May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}. Default: - The entire task input (JSON path ‘$’)

  • integration_pattern (Optional[IntegrationPattern]) – AWS Step Functions integrates with services directly in the Amazon States Language. You can control these AWS services using service integration patterns Default: - IntegrationPattern.REQUEST_RESPONSE for most tasks.

  • output_path (Optional[str]) – JSONPath expression to select select a portion of the state output to pass to the next state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: - The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path ‘$’)

  • result_path (Optional[str]) – JSONPath expression to indicate where to inject the state’s output. May also be the special value JsonPath.DISCARD, which will cause the state’s input to become its output. Default: - Replaces the entire input with the result (JSON path ‘$’)

  • result_selector (Optional[Mapping[str, Any]]) – The JSON that will replace the state’s raw result and become the effective result before ResultPath is applied. You can use ResultSelector to create a payload with values that are static or selected from the state’s raw result. Default: - None

  • timeout (Optional[Duration]) – Timeout for the state machine. Default: - None

Methods

add_catch(handler, *, errors=None, result_path=None)

Add a recovery handler for this state.

When a particular error occurs, execution will continue at the error handler instead of failing the state machine execution.

Parameters:

  • handler (IChainable) –

  • errors (Optional[Sequence[str]]) – Errors to recover from by going to the given state. A list of error strings to retry, which can be either predefined errors (for example Errors.NoChoiceMatched) or a self-defined error. Default: All errors

  • result_path (Optional[str]) – JSONPath expression to indicate where to inject the error data. May also be the special value DISCARD, which will cause the error data to be discarded. Default: $

Parameters:

  • backoff_rate (Union[int, float, None]) – Multiplication for how much longer the wait interval gets on every retry. Default: 2

  • errors (Optional[Sequence[str]]) – Errors to retry. A list of error strings to retry, which can be either predefined errors (for example Errors.NoChoiceMatched) or a self-defined error. Default: All errors
