Tasks

Create tasks

Tasks can be created using their operation specific endpoint. For example, see the convert task documentation on how to create a task for converting files.

Typically, you create a job which contains multiple tasks (for example: importing the file from S3, converting it and exporting it to S3 again).

Show a task

Show a task. Requires the task.read scope.

Query Parameters
include array, optional	Include `retries`, `depends_on_tasks`, `payload` and/or `job` in the result. Multiple include values are separated by `,`.

Returns

Attributes
id string	The ID of the task.
job_id string	The Job ID the tasks belongs to.
operation string	Name of the operation, for example `convert` or `import/s3`.
status string	The status of the task. Is one of `waiting`, `processing`, `finished` or `error`.
message string	The status message. Contains the error message if the task status is `error`.
code string	The error code if the task status is `error`.
credits integer	The amount of conversion minutes the task consumed. Available when the status is `finished`.
created_at string	ISO8601 timestamp of the creation of the task.
started_at string	ISO8601 timestamp when the task started processing.
ended_at string	ISO8601 timestamp when the task finished or failed.
depends_on_tasks object	List of tasks that are dependencies for this task. Only available if the `include` parameter was set to `depends_on_tasks`.
retry_of_task_id string	ID of the original task, if this task is a retry.
retries array	List of tasks that are retries of this task. Only available if the `include` parameter was set to `retries`.
engine string	Name of the engine.
engine_version string	Version of the engine.
payload object	Your submitted payload for the tasks. Depends on the operation type.
result object	The result of the task. Depends on the operation type. Finished tasks always do have a `files` key with the names of the result files of the task (See the example on the right).

Wait for a task

The CloudConvert API is asynchronous by default. When starting a task, the API responds immediately and you either receive the completed task via webhook notification or via polling.

As alternative, there is a synchronous option which waits until the task status is finished or error. This makes the request block until the task has been completed. Requires the task.read scope.

Requires the task.read scope. Please note that the synchronous API uses a different base URL (https://sync.api.cloudconvert.com).

We do not recommend using this for long running tasks (e.g. video encodings). Your system might automatically time out requests if there is not data transferred for a longer time.

In general, please avoid to block your application until a CloudConvert tasks completes. There might be cases in which we need to queue your task which results in longer processing times than usual. Using an asynchronous approach with webhooks is beneficial in such cases.

This endpoint was previously available at https://api.cloudconvert.com/v2/tasks/{ID}/wait. Please migrate to the new base URL (https://sync.api.cloudconvert.com) for the synchronous API because we need to turn off the old endpoint at some point.

Returns

The finished or failed task. You can find details about the task model response in the documentation about the show tasks endpoint.
