# /api/workflow/\*

OpenChat uses workflow routes for long-running or operational actions.

## Endpoints

| Endpoint                       | Purpose                      |
| ------------------------------ | ---------------------------- |
| `/api/workflow/generate-title` | Generate and save chat title |
| `/api/workflow/export-chat`    | Export chat as markdown/json |
| `/api/workflow/delete-account` | Delete user data in batches  |
| `/api/workflow/cleanup`        | Retention cleanup batches    |

## Execution Modes

* Local/non-production: inline execution.
* Production: queued execution via Upstash Workflow callbacks.

## Shared Controls

* Same-origin and auth checks for user-triggered writes.
* Rate limits on sensitive endpoints.
* Callback signature verification for workflow callbacks.

## Notable Payload Fields

* `generate-title`: `chatId`, `length`, `provider`, optional `seedText`.
* `export-chat`: `chatId`, `format` (`markdown` or `json`).
* `delete-account`: optional `batchSize`, auth-bound identity.
* `cleanup`: `retentionDays`, `batchSize`, cleanup token auth.
