I am performing a batch transform on my ES index (only transforming for once and not a continuous job). Is there an API or indicator that returns a response once the transformation is done (so that I could then stop the transform job)?

Batch transform auto-stop, so there is no task being leftover after it is done. The only "left-over" beside the transformed data are 2 tiny documents in an internal index.

If you are looking for a callback you can use in code, you can call `_stop` with `wait_for_completion` and `wait_for_checkpoint` being set to `true`. `wait_for_completion` will tell it to block and `wait_for_checkpoint` will tell it to not stop the transform in an intermediate state but let it run until a checkpoint is ready (Batch transforms have just 1 checkpoint).

Just a quick follow up, to set a query parameter for the \_stop api, is this how I should do it?

```auto
curl -X POST "localhost:9200/_transform/<jobID>/_stop?pretty" -d'
{
  "query": {
      "wait_for_completion": true,
      "wait_for_checkpoint": true
  }
}
'

```

</div>

query parameters go into the URL part:  
`curl -X POST "localhost:9200/_transform/ecommerce_transform/_stop?wait_for_completion=true&wait_for_checkpoint=true"`

(I removed `pretty`, its not needed)
