# 2.1.2

### New features

#### Bulk request (preview)

Transactions can now be set to be executed via a bulk request.

This means a combined request will be sent to M3 with as many transactions as rows in iterator table.&#x20;

If "Independent operations" option (default) is selected, connector will send one transaction per http request to M3 Rest API.

Note that this feature is in preview, please try it out and let us know what you think!

#### Runtime auth options

There are new options for runtime auth. You can now specify a different runtime auth for either&#x20;

* Client is Test bench
* Running user is specified user

This is especially useful when the 'normal' auth is OAuth2 Authorization Code, but you want to run scheduled workflows as a machine user or you are developing a new workflow and want to run it in test bench.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.novacuraflow.com/release-information/connector-services/m3-rest-connector/2.1.2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
