Over the HTTP API, you can set `/mutate?commitNow=true` for the /mutate endpoint.

For txns with multiple mutations, you can call /commit separately with the appropriate timestamp and txn keys/preds: [https://dgraph.io/docs/clients/raw-http/#committing-the-transaction](https://dgraph.io/docs/clients/raw-http/#committing-the-transaction)

When you commit, you’ll see the `commit_ts` in the extensions in the response, e.g.:

```
{
    "data": { ... },
    "extensions": {
        "txn": {
          "start_ts": 200460131, **"commit\_ts": 200460132,**...
        }
    }
}
```
