Update a custom field

put

https://app.asana.com/api/1.0/custom_fields/{custom_field_gid}

Required scope: custom_fields:write

A specific, existing custom field can be updated by making a PUT request on the URL for that custom field. 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 custom field. A custom field’s type cannot be updated. An enum custom field’s enum_options cannot be updated with this endpoint. Instead see “Work With Enum Options” for information on how to update enum_options. Locked custom fields can only be updated by the user who locked the field. Returns the complete updated custom field record.

Path Params

custom_field_gid

string

required

Globally unique identifier for the custom field.

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.

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.

Responses

200The custom field was successfully updated.

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.
