An SMS gateway address is the API endpoint or server address a business’s application connects to in order to send and receive SMS messages through an SMS gateway provider. It acts as the bridge between a website, CRM, or software system and the mobile telecom network, converting outgoing messages into a format telecom operators can deliver and routing incoming replies back to the sender’s system.
For businesses using SMSGatewayCenter, this typically refers to the API endpoint (HTTP/HTTPS URL) or SMPP server address provided after signup, which is used to authenticate requests and push messages for delivery across Indian mobile networks in compliance with DLT regulations.
