startTime

string (Timestamp format)

Output only. Marks the beginning of execution.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".

state

enum (State)

Output only. Current state of the execution.
argument

string

Input parameters of the execution represented as a JSON string. The size limit is 32KB.

Note: If you are using the REST API directly to run your workflow, you must escape any JSON string value of argument. Example: '{"argument":"{\"firstName\":\"FIRST\",\"lastName\":\"LAST\"}"}'
result

string

Output only. Output of the execution represented as a JSON string. The value can only be present if the execution's state is SUCCEEDED.
error

object (Error)

Output only. The error which caused the execution to finish prematurely. The value is only present if the execution's state is FAILED or CANCELLED.
workflowRevisionId

string

Output only. Revision of the workflow this execution is using.
callLogLevel

enum (CallLogLevel)

The call logging level associated to this execution.
status

object (Status)

Output only. Status tracks the current steps and progress data of this execution.

State

Describes the current state of the execution. More states might be added in the future.

Enums
STATE_UNSPECIFIED Invalid state.
ACTIVE The execution is in progress.
SUCCEEDED The execution finished successfully.
FAILED The execution failed with an error.
CANCELLED The execution was stopped intentionally.

Error

Error describes why the execution was abnormally terminated.

JSON representation 
{
  "payload": string,
  "context": string,
  "stackTrace": {
    object (StackTrace)
  }
}
Fields
payload

string

Error message and data returned represented as a JSON string.
context

string

Human-readable stack trace string.
stackTrace

object (StackTrace)

Stack trace with detailed information of where error was generated.

StackTrace

A collection of stack elements (frames) where an error occurred.

JSON representation 
{
  "elements": [
    {
      object (StackTraceElement)
    }
  ]
}
Fields
elements[]

object (StackTraceElement)

An array of stack elements.

StackTraceElement

A single stack element (frame) where an error occurred.

JSON representation 
{
  "step": string,
  "routine": string,
  "position": {
    object (Position)
  }
}
Fields
step

string

The step the error occurred at.
routine

string

The routine where the error occurred.
position

object (Position)

The source position information of the stack trace element.

Position

Position contains source position information about the stack trace element such as line number, column number and length of the code block in bytes.

JSON representation 
{
  "line": string,
  "column": string,
  "length": string
}
Fields
line

string (int64 format)

The source code line number the current instruction was generated from.
column

string (int64 format)

The source code column position (of the line) the current instruction was generated from.
length

string (int64 format)

The number of bytes of source code making up this stack trace element.

CallLogLevel

Describes the level of platform logging to apply to calls and call responses during workflow executions.

Enums
CALL_LOG_LEVEL_UNSPECIFIED No call logging level specified.
LOG_ALL_CALLS Log all call steps within workflows, all call returns, and all exceptions raised.
LOG_ERRORS_ONLY Log only exceptions that are raised from call steps within workflows.

Status

Represents the current status of this execution.

JSON representation 
{
  "currentSteps": [
    {
      object (Step)
    }
  ]
}
Fields
currentSteps[]

object (Step)

A list of currently executing or last executed step names for the workflow execution currently running. If the workflow has succeeded or failed, this is the last attempted or executed step. Presently, if the current step is inside a subworkflow, the list only includes that step. In the future, the list will contain items for each step in the call stack, starting with the outermost step in the main subworkflow, and ending with the most deeply nested step.

Step

Represents a step of the workflow this execution is running.

JSON representation 
{
  "routine": string,
  "step": string
}
Fields
routine

string

Name of a routine within the workflow.
step

string

Name of a step within the routine.

Methods

cancel

 Cancels an execution of the given name.

create

 Creates a new execution using the latest revision of the given workflow.

get

 Returns an execution of the given name.

list

 Returns a list of executions which belong to the workflow with the given name.
