# Workflows

The 15 multi-step API chains that the Litmus UI orchestrates behind a single user action. This is the most valuable section of the docs - none of these workflows can be reconstructed from a single endpoint reference.

:::BlockQuote
**Run any workflow live:** all 47 chains are in the [How-to folder on api.litmus.io](https://api.litmus.io/view/2s9Y5R1RvG#e7f328dd-c01f-496b-8f61-927ac6d619e8).
:::

Each workflow page includes:

- The UI action that triggers it
- A step-by-step table (method, endpoint, body, output)
- Auth notes per step (which header, which token)
- Variants and cleanup steps

## All workflows

## Pattern: Resumable Upload Sessions

Workflows 1-4 share the same resumable upload pattern:

| Phase             | Method   | What it does                        |
| ----------------- | -------- | ----------------------------------- |
| 0. Clear          | `DELETE` | Remove any stale upload session     |
| 1. Create session | `POST`   | Declare file size, get a session ID |
| 2. Upload         | `PUT`    | Stream the bytes                    |

See [Resumable Uploads](#).

## Pattern: LEM Async-Task

Workflows 11-13 use the LEM async-task envelope:

```javascript
POST .../async-task/task-with-subtasks  ->  { taskId }
GET  .../async-task/{taskId}/subtasks   ->  poll until SUCCESS
```
