# Data types

The InEvent API accepts multiple types of data and we will describe it here for you.

* **String**: regular strings that may or may not allow HTML content (depends on the attribute);
* **Boolean**: boolean values are always stored as 0 or 1;
* **Date Time**: dates and times are always stored as Unix timestamps;

All values are always sent as Strings (cast), even when they are numbers.
