Send Publiq emails from Zapier

Use the "Webhooks by Zapier → POST" action to call the Publiq API from any Zap.

No code: use an HTTP request module to call the Publiq API from any automation.

URL:     https://api.publiq.digital/v1/emails
Method:  POST
Headers:
  Authorization: Bearer YOUR_PUBLIQ_API_KEY
  Content-Type: application/json
Data (JSON):
{
  "from": "you@yourdomain.com",
  "to": "{{trigger.email}}",
  "templateKey": "welcome-email",
  "variables": { "first_name": "{{trigger.name}}" }
}

Best practices

Always call Publiq from the server — the API key goes in the Authorization header, never on the client.
On 429/5xx, retry with exponential backoff (respect Retry-After).
Prefer templateKey over inline HTML to keep content versioned.
Handle errors via the response error.code field — see Errors.
Send from a verified domain — see Domains.
