Sample - Asana API
GET/attachments

Get attachments from an object

Required scope: attachments:read

Returns the compact records for all attachments on the object. There are three possible parent values for this request: project, project_brief, and task. For a project, an attachment refers to a file uploaded to the "Key resources" section in the project Overview. For a project brief, an attachment refers to inline files in the project brief itself. For a task, an attachment refers to a file directly associated to that task.

Note that within the Asana app, inline images in the task description do not appear in the index of image thumbnails nor as stories in the task. However, requests made to GET /attachments for a task will return all of the images in the task, including inline images.

  • RetriesRetries up to 2×, 500ms backoff, 30s timeout.

4 parameters
limitintegeroptional
Results per page. The number of objects to return per page. The value must be between 1 and 100.
offsetstringoptional
Offset token. An offset to the next page returned by the API. A pagination request will return an offset token, which can be used as an input parameter to the next request. If an offset is not passed in, the API will return the first page of results. *Note: You can only pass in an offset that was returned to you via a previously paginated request.*
parentstringrequired
Globally unique identifier for the object to fetch attachments from. Must be a GID for a `project`, `project_brief`, or `task`.
opt_fieldsarray<string>optional
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. Properties can include nested fields. To learn more, see the [input/output options guide](/docs/inputoutput-options#selecting-nested-fields).

6 status codes
200Successfully retrieved the specified object's attachments.
dataarray<object>optional
next_pageobjectoptional
*Conditional*. This property is only present when a limit query parameter is provided in the request. When making a paginated request, the API will return a number of results as specified by the limit parameter. If more results exist, then the response will contain a next_page attribute, which will include an offset, a relative path attribute, and a full uri attribute. If there are no more pages available, next_page will be null and no offset will be provided. Note that an offset token will expire after some time, as data may have changed.
400This usually occurs because of a missing or malformed parameter. Check the documentation and the syntax of your request and try again.
errorsarray<object>optional
401A valid authentication token was not provided with the request, so the API could not associate a user with the request.
errorsarray<object>optional
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.
errorsarray<object>optional
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.
errorsarray<object>optional
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.
