How do I add a file to the attachments section of an asset using the REST APIs?

[CristinaVo]

Hi,

I tried to attach a text file to an asset using the assets REST API but for some reason I can't get the request right.

I took the request headers from this documentation: https://insight-javadoc.riada.io/assets-rest/#attachments_object__objectid__post because this other one doesn't describe the attachments endpoint although the endpoint exists https://developer.atlassian.com/cloud/assets/rest/api-group-aql/

My request:

POST /jsm/assets/workspace/{workspaceId}/v1/attachments/object/{objectId} HTTP/1.1

X-Atlassian-Token: no-check

Cache-Control: no-cache

Authorization: Basic XXXXXXXXXXXX
Postman-Token: XXXXXXXXXXX

Host: api.atlassian.com

Content-Type: multipart/form-data; boundary=--------------------------781657821705825765126353

 

----------------------------781657821705825765126353

Content-Disposition: form-data; name="file"; filename="fan.txt"

Content-Type: text/plain

<fan.txt>

Here is the response I get:

The request for getting the existing attachments from an asset works fine.

GET /jsm/assets/workspace/{workspaceId}/v1/attachments/object/{objectId} HTTP/1.1

Authorization: Basic XXXXXXXXXXXXXXXXXX

Postman-Token: XXXXXXXXXXXXXXX

Host: api.atlassian.com 

When I tried to add the same file to a jira issue instead of an asset the request worked.

POST /rest/api/2/issue/{issueKey}/attachments HTTP/1.1

X-Atlassian-Token: no-check

Authorization: Basic XXXXXXXXXXXXXXXXXXX
Postman-Token: XXXXXXXXXX

Please help me with some answers to the following questions:

1. What am I doing wrong at the first request? Should I use a different endpoint?
2. Is this REST API only available on jira server https://insight-javadoc.riada.io/assets-rest/#? If not, how should I use it in jira cloud
3. The endpoint which gets the attachments from an asset (the second request in the question) returns only the name of the file and other info but it doesn't return the file content. Is there a way to get the file content too?

Thank you

Hi @CristinaVo  I'm also looking for a way to attach documents to objects on Jira Asset (Ex Insight) too.
Currently it is not possible with the official and documented APIs.
There is an open issue in Atlassian here: https://jira.atlassian.com/browse/JSDCLOUD-10454

Hi @Gabriele Cecco, I eventually found out about about this issue from the Atlassian support team, and I also voted it.

Thank you very much for your answer,
