# Update effective dates for facility-group association

`PUT /facilities/{certifyFacilityId}/groups/{certifyGroupId}/effective-date`

Updates the effective start date and/or termination date for a facility-group association. Optionally cascades the date change to network participation based on the cascadeToNetworkParticipation flag. If terminationDate is provided, it must be after the effectiveDate. Mirrors the practitioner-group precedent endpoint with one deliberate divergence: the request body carries an optional changeReason field per facility-resource convention.
