# Update a change feed subscription
Source: https://www.desktopaccountingapi.com/docs/api/reference/operations/changefeedsubscriptionsupdate/

`POST https://api.desktopaccountingapi.com/v1/change-feed-subscriptions/{id}`

Operation ID: `changeFeedSubscriptions.update`. Tag: Change feed.

Changes the resources, the interval or `enabled`. Omitted fields are unchanged. A resource added here is watched from now on; a removed resource stops being polled, and adding it again later starts over from that time.

Authentication: `Authorization: Bearer <secret key>`.

Example request:

```sh
curl -X POST https://api.desktopaccountingapi.com/v1/change-feed-subscriptions/cfs_01j9x4m6v4c8k2t7q0r5s3w1zk \
  -H "Authorization: Bearer $DAAPI_SECRET_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{}'
```

## Path parameters

- `id` (string, required): Unique identifier for the change feed subscription. example `cfs_01j9x4m6v4c8k2t7q0r5s3w1zk`.

## Headers

- `Idempotency-Key` (string): Makes a write safe to retry. Repeating a key with the same request attaches to or replays the original instead of creating a second one. 1–255 printable ASCII characters, retained 7 days. Reusing a key with a different request returns `422 IDEMPOTENCY_KEY_REUSED`. 1–255 characters; example `6f1c2a0e-1f7e-4c55-9a7a-0b2d2c9e3a10`.

## Request body (application/json, required)

- `resources` (array of string): Resources to watch, each listed once. Every poll reads each of them on every subscribed connection. 1–62 items.
- `intervalMinutes` (integer): Minutes between polls of each connection, 15 to 1440. Polls run on a 15-minute schedule, so a connection is polled at the first run after its interval has passed; when several subscriptions watch the same resource, the shortest interval applies. 15 to 1440; example `15`.
- `enabled` (boolean): Turn polling on or off.

Minimal example:

```json
{}
```
