Create a task

API Reference

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 ADD string

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.

truetruefalse

The task to create.

It can either be a header above a list of tasks in a list view or a column in a board view of "My tasks." The assignee_section property will be returned in the response only if the request was sent by the user who is the assignee of the task. Note that you can only write to assignee_section with the gid of an existing section visible in the user's "My tasks" list.

assignee_section object

custom_fields

array of objects

Array of custom field values applied to the task. These represent the custom field values recorded on this project for a particular custom field. For example, these custom field values will contain an enum_value property for custom fields of type enum, a text_value property for custom fields of type text, and so on. Please note that the gid returned on each custom field value is identical to the gid of the custom field, which allows referencing the custom field metadata through the /custom_fields/custom_field_gid endpoint.

custom_fields

object

Custom Fields store the metadata that is used in order to add user-specified information to tasks in Asana. Be sure to reference the custom fields developer documentation for more information about how custom fields relate to various resources in Asana.

Users in Asana can lock custom fields, which will make them read-only when accessed by other users. Attempting to edit a locked custom field will return HTTP error code 403 Forbidden.

gid

string

Globally unique identifier of the resource, as a string.

resource_type

string

The base type of this resource.

name

string

The name of the custom field.

type

string

enum

Deprecated: new integrations should prefer the resource_subtype field. The type of the custom field. Must be one of the given values.

text``enum``multi_enum``number``date``people

enum_options

array of objects

Conditional. Only relevant for custom fields of type enum or multi_enum. This array specifies the possible values which an enum custom field can adopt. To modify the enum options, refer to working with enum options.

enum_options

object

Enum options are the possible values which an enum custom field can adopt. An enum custom field must contain at least 1 enum option but no more than 500.

You can add enum options to a custom field by using the POST /custom_fields/custom_field_gid/enum_options endpoint.

It is not possible to remove or delete an enum option. Instead, enum options can be disabled by updating the enabled field to false with the PUT /enum_options/enum_option_gid endpoint. Other attributes can be updated similarly.

On creation of an enum option, enabled is always set to true, meaning the enum option is a selectable value for the custom field. Setting enabled=false is equivalent to “trashing” the enum option in the Asana web app within the “Edit Fields” dialog. The enum option will no longer be selectable but, if the enum option value was previously set within a task, the task will retain the value.

Enum options are an ordered list and by default new enum options are inserted at the end. Ordering in relation to existing enum options can be specified on creation by using insert_before or insert_after to reference an existing enum option. Only one of insert_before and insert_after can be provided when creating a new enum option.

An enum options list can be reordered with the POST /custom_fields/custom_field_gid/enum_options/insert endpoint.

precision

integer

Only relevant for custom fields of type Number. This field dictates the number of places after the decimal to round to, i.e. 0 is integer values, 1 rounds to the nearest tenth, and so on. Must be between 0 and 6, inclusive. For percentage format, this may be unintuitive, as a value of 0.25 has a precision of 0, while a value of 0.251 has a precision of 1. This is due to 0.25 being displayed as 25%. The identifier format will always have a precision of 0.
