Usage
Section titled UsageCustom variables are additional information on the screen, the user or the session, sent along with screenviews.
For example, they can include information on the current layout of a screen, like dark or light mode.
Limits
Section titled LimitsOn the server side
Section titled On the server side- It is possible to save up to 20 distinct custom variables per screenview. If more are received, only the first 20 custom variables, based on their
index
value, will be kept. - The
index
value of custom variable is used to determine which custom variable to be kept. Onlyindex
value between 1 and 20 will be taken into account.
On the SDK side
Section titled On the SDK side- Every custom variable is composed of
index
,name
andvalue
. - If you are using the same
index
twice in a single screen only the first (name
,value
) pair associated with theindex
will be kept. - In case
name
(max. 512 characters) orvalue
(max. 255 characters) maximum characters length is reached, the SDK will automatically trim the exceeding characters. - If
name
orvalue
are empty, the SDK will instead send the literal string"cs-empty"
. - Use a consistent
index
for a given variable within an application - for instance, if the “screen layout” is collected with anindex
of 3, use the slot 3 for this information on every screen of the application.
