You may want to know more about the `fields/keys` within each callback event -- some fields may have certain conditions to be mapped and some are mapped directly. Some fields are mandatory for the callback event to be sent and some are not. In this Data Dictionary, you will find all the relevant information you would want to know.  

:::hint{type="info"}
The following sheet is still a work in progress. We are working on adding all the callback events. Note that the fields highlighted in green are Mandatory/Required fields.
