    Features

    Everything to integrate WhatsApp into your business

    Send via REST API

    Text, image, video, audio and documents to any number with WhatsApp, with a private token per client.

    PDF invoices and documents

    The PDF arrives as a native attachment that opens in WhatsApp — never as a link. Send via URL, base64 or upload.

    Multiple numbers (instances)

    Connect numbers by QR code, with live status (connected, connecting, error). Each client's numbers are isolated.

    Official and unofficial WhatsApp

    Support for the Evolution API (unofficial) and the Meta Cloud API (official WhatsApp Business API).

    Number verification

    Check whether a number has WhatsApp before sending — free, without using quota.

    Per-client quotas and billing

    Daily or monthly quota, manageable plans, subscriptions and automatic usage-based billing.

    Webhooks to receive messages

    Signed webhooks (HMAC-SHA256) deliver incoming messages to your system in real time.

    Multi-client panel and reselling

    Each client with its own token, instances and limits. Ideal for agencies reselling WhatsApp API.

    FAQ

    Frequently asked questions about Gateway

    Do I need the official WhatsApp Business API?
    Not necessarily. Gateway supports both unofficial WhatsApp (Evolution API), faster to get started, and the official Meta Cloud API. Choose based on your needs.
    Can I send PDF invoices over WhatsApp?
    Yes. The PDF (e.g. an invoice generated in your system) arrives as a native attachment that opens in WhatsApp, sent via URL, base64 or direct upload.
    How do I integrate it into my system?
    Through a REST API with a private token. We provide examples in cURL, PHP (Laravel) and JavaScript, and signed webhooks to receive messages.
    Can I resell the service to my clients?
    Yes. The panel is multi-client: each client has its own token, numbers and limits, with per-account billing — ideal for agencies and resellers.
    What happens when I run out of quota?
    The API returns an HTTP 429 with the detail (period, used, limit, remaining). You can check the quota in real time at the usage endpoint.
