Mappings

When configuring your connection, you can optionally/additionally define custom mappings to transform the payload to from and/or to a format, which is convenient for the integrated devices or application, or even to multiple formats.

Following mapping options can be activated/de-activated via our user interface, in the General section:

Normalize outgoing event payload in thing format

In case your device or application is not aware of or is not interested in Eclipse Ditto protocol compliant messages, you should activate this checkbox to emit normalized JSON payloads for outgoing thing updates. The normalized payloads contain the updated content of your Thing and only include the conversation information (e.g. path of change) as additional context information.

Enable custom JavaScript based payload mapping

By activating this checkbox, the user interface will offer a new section, where you can add the custom mapping in JavaScript.

A mapping can result into one or multiple messages, according to your needs. Note however, that additional messages will be accounted respectively.

note Please also take note of the restrictions.
