Create a batch to upload data about a particular business.

This endpoint returns an <code>id</code> that should be put into all /business/data/XXX endpoints.

Why use batch?

• with the batch, you can send accounts transactions in chunks instead of sending them all in a single API call
• with the batch, you can share more <code>context</code> (see parameter below) with us which enables us to update credit lines more accurately
