We are excited to announce the developer preview of our new API documentation for AWS SDK for JavaScript v3. Please follow instructions on the landing page to leave us your feedback.

Class StartWorkflowExecutionCommandProtected

Starts an execution of the workflow type in the specified domain using the provided workflowId and input data.

This action returns the newly started workflow execution.

Access Control

You can use IAM policies to control this action's access to Amazon SWF resources as follows:

  • Use a Resource element with the domain name to limit the action to only specified domains.

  • Use an Action element to allow or deny permission to call this action.

  • Constrain the following parameters by using a Condition element with the appropriate keys.

    • tagList.member.0: The key is swf:tagList.member.0.

    • tagList.member.1: The key is swf:tagList.member.1.

    • tagList.member.2: The key is swf:tagList.member.2.

    • tagList.member.3: The key is swf:tagList.member.3.

    • tagList.member.4: The key is swf:tagList.member.4.

    • taskList: String constraint. The key is swf:taskList.name.

    • workflowType.name: String constraint. The key is swf:workflowType.name.

    • workflowType.version: String constraint. The key is swf:workflowType.version.

If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

Example

Use a bare-bones client and the command you need to make an API call.

import { SWFClient, StartWorkflowExecutionCommand } from "@aws-sdk/client-swf"; // ES Modules import
// const { SWFClient, StartWorkflowExecutionCommand } = require("@aws-sdk/client-swf"); // CommonJS import
const client = new SWFClient(config);
const input = { // StartWorkflowExecutionInput
domain: "STRING_VALUE", // required
workflowId: "STRING_VALUE", // required
workflowType: { // WorkflowType
name: "STRING_VALUE", // required
version: "STRING_VALUE", // required
},
taskList: { // TaskList
name: "STRING_VALUE", // required
},
taskPriority: "STRING_VALUE",
input: "STRING_VALUE",
executionStartToCloseTimeout: "STRING_VALUE",
tagList: [ // TagList
"STRING_VALUE",
],
taskStartToCloseTimeout: "STRING_VALUE",
childPolicy: "TERMINATE" || "REQUEST_CANCEL" || "ABANDON",
lambdaRole: "STRING_VALUE",
};
const command = new StartWorkflowExecutionCommand(input);
const response = await client.send(command);
// { // Run
// runId: "STRING_VALUE",
// };

Throws

DefaultUndefinedFault (client fault)

The StartWorkflowExecution API action was called without the required parameters set.

Some workflow execution parameters, such as the decision taskList, must be set to start the execution. However, these parameters might have been set as defaults when the workflow type was registered. In this case, you can omit these parameters from the StartWorkflowExecution call and Amazon SWF uses the values defined in the workflow type.

If these parameters aren't set and no default parameters were defined in the workflow type, this error is displayed.

Throws

LimitExceededFault (client fault)

Returned by any operation if a system imposed limitation has been reached. To address this fault you should either clean up unused resources or increase the limit by contacting AWS.

Throws

OperationNotPermittedFault (client fault)

Returned when the caller doesn't have sufficient permissions to invoke the action.

Throws

TypeDeprecatedFault (client fault)

Returned when the specified activity or workflow type was already deprecated.

Throws

UnknownResourceFault (client fault)

Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.

Throws

WorkflowExecutionAlreadyStartedFault (client fault)

Returned by StartWorkflowExecution when an open execution with the same workflowId is already running in the specified domain.

Throws

SWFServiceException

Base exception class for all service exceptions from SWF service.
