Steps
In Project Settings > Webhooks, generate a signing secret and register the events and target URL you want notified on (webhook subscriptions are dashboard-configured; there is no API endpoint to create them).
Verify each inbound webhook using the x-voucherify-signature header (HMAC-SHA256 over the raw request body with your signing secret) and return a 2xx within the documented timeout.
Separately, set up a Distribution (Engagement > Distributions) to define a trigger (e.g. segment entered, order paid) and an action/channel (email, SMS, webhook) for automatically messaging customers.
To assign a voucher code to a customer purely via API, POST /v1/publications with a campaign name (or specific voucher code) and a customer object.
Handle delivery yourself (email/SMS) if you're not using a dashboard-configured Distribution channel, since publication alone only allocates the code.
Known gotchas
Failed webhook deliveries retry on a backoff schedule and are disabled/paused after a bounded number of consecutive failures, requiring manual re-enable.
Webhook calls and distribution messages each have separate daily/monthly quotas from your general API rate limit — new accounts in particular may be capped very low on messages until an anti-spam check passes.
POST /v1/publications requires an unambiguous voucher source (a campaign name or a specific code) — sending both or neither will fail.
