Enterprise-grade WhatsApp Business API for automated, scalable customer communication
Designed for medium and large organisations requiring programmatic access to WhatsApp messaging
The WhatsApp Business API allows businesses to integrate WhatsApp messaging directly into their applications, platforms, and workflows. Messages are sent and received through secure APIs rather than a mobile application.
Gateway.sa provides enterprise-grade access to the WhatsApp API, supporting high-volume messaging, automation, and system integration — backed by official WhatsApp Business Platform access.

Yes. Messages sent outside the 24-hour customer service window require pre-approved message templates. Within the 24-hour window (after a user initiates a conversation), you can send free-form messages. Gateway.sa assists with creating and getting your templates approved quickly.
The WhatsApp API supports images, documents (PDF, Word, Excel), audio files, and video. This enables rich, branded communication — from sending invoices and tickets as PDFs to sharing product images directly in chat.
Users must explicitly opt in to receive WhatsApp messages from your business. This can be done through your website, app, SMS confirmation, or at point of sale. Gateway.sa's platform includes automated compliance checks to ensure all messaging adheres to opt-in requirements.
Gateway.sa provides RESTful APIs with comprehensive documentation, code samples in all major programming languages, and webhook support for inbound messages. Our technical team offers end-to-end onboarding support to get your integration live as quickly as possible.
