URL parameters to event properties - Docs

Converts URL query parameters to event properties

Configuration

Option	Description
`URL query parameters to convert` Type: string Required: False	Comma separated list of URL query parameters to capture. Leaving this blank will capture nothing.
`Prefix` Type: string Required: False	Add a prefix to the property name e.g. set it to 'prefix_' to get followerId -> prefix_followerId
`Suffix` Type: string Required: False	Add a suffix to the property name e.g. set it to '_suffix' to get followerId -> followerId_suffix
`Ignore the case of URL parameters` Type: choice Required: False	Ignores the case of parameters e.g. when set to true than followerId would match FollowerId, followerID, FoLlOwErId and similar
`Add to user properties` Type: choice Required: False	Additionally adds the property to the user properties
`Add to user initial properties` Type: choice Required: False	Additionally adds the property to the user initial properties. This will add a prefix of 'initial_' before the already fully composed property e.g. initial_prefix_followerId_suffix
`Always JSON stringify the property data` Type: choice Required: False	If set, always store the resulting data as a JSON array. (Otherwise, single parameters get stored as-is, and multi-value parameters get stored as a JSON array.)
