GoHighLevel integrations with Croatian tools (Fiskal, SEPA, Viber, WhatsApp)

The most common question we get from Croatian agencies evaluating GoHighLevel is: "Does it work with our fiscal, SEPA and Viber?". Short answer: yes — but not equally easily. This is a shortlist of integrations we actually run in production, with a realistic effort estimate.

Native (no developer)

• Email (SMTP/Mailgun/SendGrid) — 10 minutes.
• SMS (Twilio, LINK Mobility) — HR numbers work, €0.04–0.06/msg.
• WhatsApp Business — via Twilio or native Meta. Number verification 5–14 days.
• Stripe / PayPal / Wise — cards, SEPA transfers, subscriptions.
• Google Calendar / Outlook / iCloud — two-way sync.
• Zapier / Make — bridge to 2400+ apps.

Via Zapier / Make (no code, 30–90 min setup)

• Fina e-Invoice — GHL invoice → Zapier → Fina API (needs Fina cert).
• Minimax / Pantheon / Synesis — contacts / payments to accounting.
• Viber Business Messages — via LINK Mobility or Infobip webhook.
• Google Business Profile reviews — auto-request after appointment.

Custom (webhook + 1–3 dev days)

• RBA / Erste / PBZ banking auto-reconcile — no open API, done via IBAN + reference number matching.
• eVisitor guest registration (tourism) — custom middleware.
• Croatian health insurance (HZZO) — no public API today.

Budgeting

| Type | Time | One-off cost | |------|------|--------------| | Native | 10 min | €0 | | Zapier/Make | 30–90 min | €50–200 + monthly | | Custom webhook | 1–3 days | €400–1500 |

Recommended order for a new install

1. Email + SMS + WhatsApp.
2. Google Calendar.
3. Stripe or SEPA.
4. Zapier bridge to accounting.
5. Custom integrations only after everything else is stable.
