Creates a new task definition.

Request body

Parameter	Description	Type	Required/Optional
name	A unique name for the task.	string	Required.
description	A brief description of the task.	string	Optional.
retryCount	The number of retry attempts if the task fails.	integer	Optional.
retryDelaySeconds	The time (in seconds) to wait before each retry attempt.	integer	Optional.
backOffScaleFactor	The value multiplied with retryDelaySeconds to determine the interval for retry.	integer	Optional.
retryLogic	The policy that determines the retry mechanism for the tasks. Supported values: FIXED–Retries after a fixed interval defined by retryDelaySeconds. LINEAR_BACKOFF–Retries occur with a delay that increases linearly based on retryDelaySeconds x backoffScaleFactor x attemptNumber. EXPONENTIAL_BACKOFF–Retries occur with a delay that increases exponentially based on retryDelaySeconds x (backoffScaleFactor ^ attemptNumber).	string	Optional.
rateLimitPerFrequency	The maximum number of task executions that can be scheduled in a given duration.	integer	Optional.
rateLimitFrequencyInSeconds	The frequency window (in seconds) for the rate limit.	integer	Optional.
concurrentExecLimit	The number of task executions that can be executed concurrently.	integer	Optional.
timeOutSeconds	Time (in seconds) for the task to reach a terminal state before it gets marked as TIMED_OUT. No timeout occurs if the value is set to 0.	integer	Required.
responseTimeoutSeconds	The maximum duration in seconds that a worker has to respond to the server with a status update before it gets marked as TIMED_OUT.	integer	Optional.
pollTimeoutSeconds	Time (in seconds), after which the task is marked as TIMED_OUT if not polled by a worker. No timeout occurs if the value is set to 0.	integer	Optional.
timeoutPolicy	The policy for handling timeout. Supported values: RETRY–Retries the task based on the retry configuration. TIME_OUT_WF–The task is marked as TIMED_OUT and is terminated, which also sets the workflow status as TIMED_OUT. ALERT_ONLY–An alert message is logged when the timeout occurs. To create a task that never times out, set timeoutSeconds and pollTimeoutSeconds to 0.	string	Optional.
totalTimeoutSeconds	The total duration (in seconds) after which the task will be TIMED_OUT, regardless of the retry configuration. Once this duration is reached, no further retries will be attempted.	integer	Required.
enforceSchema	Whether to enforce input/output schema validation for all instances of the task. Set to true to enable validation or false to disable.	boolean	Optional.
inputSchema	The schema parameters to be used as input schema for the task definition. Learn more about creating and using schemas.	object	Required if enforceSchema is set to true.
outputSchema	The schema parameters to be used as output schema for the task definition. Learn more about creating and using schemas.	object	Required if enforceSchema is set to true.
inputTemplate	The default template values to be supplied for every instance of the task definition. Learn more about using input templates.	object	Optional.
inputKeys	Keys representing the expected input for the task.	array	Optional.
outputKeys	Keys representing the expected output from the task.	array	Optional.
tags	A key-value map to add tags to the task definition. Each tag consists of a key associated with a corresponding value.	object	Optional.
ownerEmail	The email address of the user creating the task definition.	string	Required.
