Webhook behavior in Plaid’s Sandbox and Development environments will mimic behavior in Plaid’s Production environment. That is, creating an Item
in either environment will trigger INITIAL_UPDATE
and HISTORICAL_UPDATE
webhooks; updating an Item
webhook will trigger a WEBHOOK_UPDATE_ACKNOWLEDGED
webhook; if a Development environment’s Item
has a transaction that is removed, a TRANSACTIONS_REMOVED
webhook will be triggered; and if an Item
is in an error state, an ERROR
webhook will be triggered.
