-# Asynchronous Processing
-
-## Introduction
-
-Starting from version 0.5, Langflow introduces a new feature to its API: the _`sync`_ flag. This flag allows users to opt for asynchronous processing of their flows, freeing up resources and enabling better control over long-running tasks.
-This feature supports running tasks in a Celery worker queue and AnyIO task groups for now.
-
-<Admonition type="warning" caption="Experimental Feature">
-  This is an experimental feature. The default behavior of the API is still
-  synchronous processing. The API may change in the future.
-</Admonition>
-
-## The _`sync`_ Flag
-
-The _`sync`_ flag can be included in the payload of your POST request to the _`/api/v1/run/<your_flow_id>`_ endpoint.
-When set to _`false`_, the API will initiate an asynchronous task instead of processing the flow synchronously.
-
-### API Request with _`sync`_ flag
-
-```bash
-curl -X POST \
-  http://localhost:3000/api/v1/run/<your_flow_id> \
-  -H 'Content-Type: application/json' \
-  -H 'x-api-key: <your_api_key>' \
-  -d '{"input_value": "Message", "tweaks": {}, "sync": false}'
-```
-
-Response:
-
-```json
-{
-  "result": {
-    "output": "..."
-  },
-  "task": {
-    "id": "...",
-    "href": "api/v1/task/<task_id>"
-  },
-  "session_id": "...",
-  "backend": "..." // celery or anyio
-}
-```
-
-## Checking Task Status
-
-You can check the status of an asynchronous task by making a GET request to the `/task/{task_id}` endpoint.
-
-```bash
-curl -X GET \
-  http://localhost:3000/api/v1/task/<task_id> \
-  -H 'x-api-key: <your_api_key>'
-```
-
-### Response
-
-The endpoint will return the current status of the task and, if completed, the result of the task. Possible statuses include:
-
-- _`PENDING`_: The task is waiting for execution.
-- _`SUCCESS`_: The task has completed successfully.
-- _`FAILURE`_: The task has failed.
-
-Example response for a completed task:
-
-```json
-{
-  "status": "SUCCESS",
-  "result": {
-    "output": "..."
-  }
-}
-```
