Request body

metadataobject

An arbitrary object for storage purpose only. You can put anything here like your internal customer id associated with the call. Not used for processing. You can later get this field from the call object. Size limited to 50kB max.

data_storage_setting'everything' | 'everything_except_pii' | 'basic_attributes_only'

Data storage setting for this call. Overrides the agent's default setting. "everything" stores all data, "everything_except_pii" excludes PII when possible, "basic_attributes_only" stores only metadata. Cannot be downgraded from more restrictive to less restrictive settings.

override_dynamic_variablesobject nullable

Override dynamic variables represented as key-value pairs of strings. Setting this will override or add the dynamic variables set in the agent during the call. Only need to set the delta where you want to override, no need to set the entire dynamic variables object. Setting this to null will remove any existing override.

custom_attributesobject

Custom attributes for the call
