Wire Vaakio into
everything else.
A full REST API with scoped keys, real-time webhooks for every subscriber and campaign event, and OAuth2 partner apps so tools like Zapier and Make connect without you pasting secrets.
curl https://app.vaakio.com/api/v1/subscribers \ -H "Authorization: Bearer vk_live_…" \ -H "Content-Type: application/json" \ -d '{ "email": "sarah@brandco.com", "lists": ["vip"] }' // 201 Created { "id": "sub_9f2a…", "status": "subscribed" }
Built for your stack,
not just ours.
Scripts, no-code automations, e-commerce platforms, and partner apps all connect through the same versioned, documented surface.
REST API v1
Campaigns, subscribers, lists, forms, automations, and events. Opaque IDs, cursor pagination, RFC 7807 errors, and a live OpenAPI reference.
Webhooks
Subscribe to opens, clicks, subscribes, unsubscribes, and campaign events. Signed payloads, automatic retries, and one-click replay from the dashboard.
Zapier & Make
Partner apps authenticate with OAuth2 and PKCE — a consent screen, not a credential paste. Approve exactly the scopes each tool needs.
E-commerce connections
Connect a store and orders flow in as subscriber events, ready to trigger automations and feed reporting.
Every key does
exactly one job.
Give a key only the scopes it needs and an optional expiry. Keys are shown once and stored as a hash. Every response carries your rate-limit budget so integrations back off cleanly instead of guessing.
