Programmatically insert task annotations

Hello,

I’m trying to integrate an external tool to automate some operations using CVAT API. I’m already able to perform most of the operations such as authenticating, creating tasks, listing tasks, uploading videos to tasks and label definitions/configurations to tasks.

But I’m currently struggling with uploading annotations into a task.

I already have a parser that converts from my annotation format to the format described on the endpoint /tasks/{id}/annotations in the /api/swagger docs, if I get my converted annotations json and use the PUT /tasks/{id}/annotations route on the swagger Try it out function it returns me 200 and creates the annotations just fine.

But when using my python tool it returns me 200 and the annotation is not getting created in the task.

Am I missing a header?

Here’s my HTTP debug logs:

Here’s a snippet of my generic method for sending requests to CVAT API, it’s currently working for the other routes.

# ...

if data:
    data = json.dumps(data)

prepped_request = Request(
    method=method,
    url=endpoint_url,
    headers=headers,
    data=data,
    params=params,
    files=files,
    cookies=cookies
)

# ...

response = session.send(prepped_request)

Ok I found /tasks/{id}/status

If I put a time.sleep(10) between creating the task + uploading the video for a task and uploading the annotations it works… is there any way for me to poll on the task to check if it’s ready to receive the annotations upload?
