It is one REST API with one API key (keys start with sghcp_) to send SMS, WhatsApp, RCS and email from your application. You create the key in the panel under Unified CPaaS API, send one request and get one message ID with the status of every channel. The existing SMS, WhatsApp and email APIs keep working as they are.
You choose a route, for example WhatsApp first, then RCS, then SMS or email. If a message fails, or is not delivered within the time you set, the next channel is tried automatically. Every channel in the route is checked when you send, so a missing template or sender is reported at once instead of failing later.
Yes. Official SDKs are available for Node.js, Python, PHP, Java, .NET, Go and Ruby, with source code on GitHub. See SMSGatewayHub SDKs for install commands and examples.
Messages are charged from one INR wallet at your rate for each channel, and the usage report shows where your balance went. WhatsApp also needs an active WhatsApp plan; the plan fee is paid separately and is never taken from the wallet. See pricing.
Each message has a live status for every channel it tried. Read it with the status call of the API, or receive signed webhooks on your server, and see all channels together in the panel delivery reports.
Create a free account, generate your API key in the panel and send one HTTPS request with your sender ID, the mobile number and the message. New accounts start in sandbox (test) mode, so you can test the integration first and go live after DLT registration. Step by step: OTP SMS API integration guide and the full API documentation.
Any language that can make an HTTPS request can use the REST / HTTP API. Official SDKs are available for Node.js, Python, PHP, Java, .NET, Go and Ruby, and high-volume senders can connect over SMPP. Ready integrations: WordPress / WooCommerce plugin, WebEngage and Odoo CRM. Example code: PHP and Python integration guide.
