Update a task

put

https://app.asana.com/api/1.0/tasks/{task_gid}

Required scope: tasks:write

A specific, existing task can be updated by making a PUT request on the URL for that task. Only the fields provided in the data block will be updated; any unspecified fields will remain unchanged.

When using this method, it is best to specify only those fields you wish to change, or else you may overwrite changes made by another user since you last retrieved the task.

Returns the complete updated task record.

Path Params

task_gid

string

required

The task to operate on.

Query Params

opt_fields

array of strings

This endpoint returns a resource which excludes some properties by default. To include those optional properties, set this query parameter to a comma-separated list of the properties you wish to include.

opt_fields

opt_pretty

boolean

Provides “pretty” output. Provides the response in a “pretty” format. In the case of JSON this means doing proper line breaking and indentation to make it readable. This will take extra time and increase the response size so it is advisable only to use this during debugging.

Body Params

The task to update.

data

object

Full object requires scope: tasks:read

The task is the basic object around which many operations in Asana are centered.

200Successfully updated the specified task.

400This usually occurs because of a missing or malformed parameter. Check the documentation and the syntax of your request and try again.

401A valid authentication token was not provided with the request, so the API could not associate a user with the request.

403The authentication and request syntax was valid but the server is refusing to complete the request. This can happen if you try to read or write to objects or properties that the user does not have access to.

404Either the request method and path supplied do not specify a known action in the API, or the object specified by the request does not exist.

500There was a problem on Asana’s end. In the event of a server error the response body should contain an error phrase. These phrases can be used by Asana support to quickly look up the incident that caused the server error. Some errors are due to server load, and will not supply an error phrase.
