onBrevoTransactionalEvent is the broad subscription for delivery,
engagement, bounce, invalid-address, spam, unsubscribe, and provider-error
events. Use a typed helper when only one semantic category matters.
Example
Options
account?: string | IntegrationAccountReference<"brevo"> selects a static
Brevo API-key binding and defaults to the project’s default binding. A signal
cannot choose the watched account at runtime.
Trigger data
occurredAt is Unix time in seconds. data preserves the complete
provider-native webhook, including fields Automate.ax has not promoted. Email
and message identity can be absent on some provider events. Automate.ax manages
one authenticated, non-batched transactional webhook per connected account and
deduplicates exact provider retries.
If one automation subscribes through both this broad helper and a matching
typed helper, the same provider callback intentionally emits once to each
subscription.
