POST /attachments
Required scope: attachments:write
Upload an attachment.
This method uploads an attachment on an object and returns the compact record for the created attachment object. This is possible by either:
- Providing the URL of the external resource being attached, or
- Downloading the file content first and then uploading it as any other attachment. Note that it is not possible to attach files from third party services such as Dropbox, Box, Vimeo & Google Drive via the API
The 100MB size limit on attachments in Asana is enforced on this endpoint.
This endpoint expects a multipart/form-data encoded request containing the full contents of the file to be uploaded.
Requests made should follow the HTTP/1.1 specification that line
terminators are of the form CRLF or \r\n outlined
here in order for the server to reliably and properly handle the request.
For file names that contain non-ASCII characters, the file name should be URL-encoded. For example, a file named résumé.pdf should be encoded as
r%C3%A9sum%C3%A9.pdf and the filename parameter in the Content-Disposition header should be set to the encoded file name.
Below is an example of a cURL request with the Content-Disposition header:
export ASANA_PAT="<YOUR_ASANA_PERSONAL_ACCESS_TOKEN>"
export PARENT_ID="<PARENT_GID>"
export ENCODED_NAME="r%C3%A9sum%C3%A9.pdf"
curl --location 'https://app.asana.com/api/1.0/attachments' \
--header 'Content-Type: multipart/form-data' \
--header 'Accept: application/json' \
--header "Authorization: Bearer $ASANA_PAT" \
--form "parent=$PARENT_ID" \
--form "file=@/Users/exampleUser/Downloads/résumé.pdf;headers=\"Content-Disposition: form-data; name="file"; filename="$ENCODED_NAME.pdf"; filename*=UTF-8''$ENCODED_NAME.pdf\""

Query parameters
| Name | Type | Required | Description |
|---|---|---|---|
opt_pretty |
Boolean | No |
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. |
opt_fields[] |
Array | No |
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. |
