<ResponseField name="id" type="string">
  ID of the consumer.
</ResponseField>

<ResponseField name="stream_id" type="string">
  ID of the stream the consumer reads from.
</ResponseField>

<ResponseField name="deliver_policy" type="string">
  Where in the stream the consumer starts.

  * `all` (default): the consumer will start from the beginning of the stream.
  * `new`: the consumer will start from the most recent message.
  * `last`: the consumer will start from the last message it received.
  * `1h`: the consumer will start from the most recent message from the last hour.
</ResponseField>

<ResponseField name="ack_wait_ms" type="integer">
  How long to wait for a message to be acknowledged, in milliseconds. Defaults to `30000` (30 seconds).

  If a worker doesn't acknowledge a message within this time, the message will be redelivered (i.e. reappear for other workers to process).
</ResponseField>

<ResponseField name="max_deliver" type="integer">
  Maximum number of times a message can be redelivered to workers. For example, if a message causes your workers to crash, it will be redelivered up to `max_deliver` times before being discarded.

  Defaults to `-1`, which means there is no maximum.
</ResponseField>

<ResponseField name="max_ack_pending" type="integer">
  Maximum number of outstanding, acknowledged messages a consumer will allow at a time. Defaults to `1000`.

  After your workers have checked out `max_ack_pending` messages, the consumer will stop delivering messages until some are acknowledged.
</ResponseField>

<ResponseField name="metadata" type="object">
  Metadata for the sync. This is a JSON object that you can use to store any additional information you want to associate with the sync.
</ResponseField>

<ResponseField name="created_at" type="string">
  Timestamp of when the sync was created, in ISO 8601 format.
</ResponseField>

<ResponseField name="updated_at" type="string">
  Timestamp of when the sync was last updated, in ISO 8601 format.
</ResponseField>
