Official WhatsApp Cloud API & Webhooks. Built for Existing CRMs.
Already have HubSpot, Zoho, Salesforce, or a custom ERP? Hitam provides verified Meta Cloud WhatsApp APIs and low-latency webhooks so you can trigger messages, send OTPs, and receive customer replies directly in your existing tech stack.
Keep your existing CRM while unlocking official WhatsApp superpowers
Many enterprises love their existing CRM or custom-built internal ERP, but lack a direct, compliant way to send and receive WhatsApp messages at scale. Hitam's WhatsApp API bridges this gap by offering developer-friendly REST endpoints, instant webhook triggers, template approval tooling, and green-tick verification assistance without forcing you to switch your core database.
Solves the limitation of third-party CRMs lacking native or affordable WhatsApp support, avoiding risky unofficial scraping bots that get business phone numbers banned.
