Manage Event Rules - Markifact

Creates, updates, deletes or reorders Google Analytics 4 event rules on a data stream: Create Event rules derive a new event from a matching one (e.g. generate_lead from form_submit) and Modify Event rules change parameters of matching events, without code changes.

Inputs

Field	Type	Required	Default	Description
`account`	array (also accepts a comma-separated string)	No	-	The GA4 property that owns the data stream. Only one property at a time.
`data_stream_id`	string	Yes	-	Numeric id of the data stream the rule belongs to, e.g. ‘7613215464’. Read it from ga4_get_property_settings with setting ‘data_streams’.
`rule_type`	string or SelectableOption	Yes	-	‘create’ for Create Event rules, which make a new event from a matching source event (e.g. generate_lead from form_submit); ‘edit’ for Modify Event rules, which change parameters of a matching event in place. Options: ‘create’, ‘edit’.
`action`	string or SelectableOption	Yes	-	‘create’, ‘update’ or ‘delete’ a rule; ‘reorder’ sets the processing order of all Modify Event rules on the stream (rule_type ‘edit’ only). Options: ‘create’, ‘update’, ‘delete’, ‘reorder’.
`rule_id`	string	No	-	Numeric id of the rule to update or delete, e.g. ‘1234567890’.
`destination_event`	string	No	-	Create Event rules: name of the new event, e.g. ‘generate_lead’. Under 40 characters, letters, digits and underscores only. Required on create.
`display_name`	string	No	-	Modify Event rules: name of the rule shown in GA4 (max 255 chars). Required on create.
`event_conditions`	array of object or string	No	-	Conditions a source event must meet, as the Admin API eventConditions array (object or JSON string), sent as-is: each has field (an event parameter name or ‘event_name’), comparisonType (EQUALS, EQUALS_CASE_INSENSITIVE, CONTAINS, CONTAINS_CASE_INSENSITIVE, STARTS_WITH, STARTS_WITH_CASE_INSENSITIVE, ENDS_WITH, ENDS_WITH_CASE_INSENSITIVE, GREATER_THAN, GREATER_THAN_OR_EQUAL, LESS_THAN, LESS_THAN_OR_EQUAL, REGULAR_EXPRESSION, REGULAR_EXPRESSION_CASE_INSENSITIVE), value and optional negated. Example: [{“field”:“event_name”,“comparisonType”:“EQUALS”,“value”:“form_submit”},{“field”:“form_id”,“comparisonType”:“EQUALS”,“value”:“contact”}]. One to ten conditions. Required on create.
`source_copy_parameters`	boolean	No	-	Create Event rules: copy the source event’s parameters onto the new event.
`parameter_mutations`	array of object or string	No	-	Parameters to set on the resulting event, as the Admin API parameterMutations array (object or JSON string), applied in order: [{“parameter”:“lead_source”,“parameterValue”:“website”}]. Use the value ‘[[param]]’ to copy another parameter. Up to 20 mutations. Required on create for Modify Event rules, optional for Create Event rules.
`rule_ids`	string or array of string	No	-	reorder only: every Modify Event rule id on the stream in the desired processing order, e.g. [‘123’, ‘456’].
