Graph API version 18.0 expires
Who is affected
Stores whose Conversions API integration still calls v18.0
What it changes
Event uploads on that version are refused, so purchases stop reaching Meta until the integration is updated.
What to do
Meta's API versions expire in steps. An integration that has not been updated stops sending your events without warning, and it is the app publisher who has to ship the update.
