Frequently asked questions
About the SMS API and SMS Gateway.
What is an SMS Gateway?
An SMS Gateway connects a business system or application to mobile networks, allowing the system to send and receive SMS and track delivery statuses.
What is the difference between an SMS API and an SMS Gateway?
An SMS Gateway is the infrastructure that routes messages. An SMS API is the interface developers use to connect a system to that infrastructure.
Can the SMS API be integrated with our HR system, CMS or CRM?
Yes. Any system that can make HTTPS requests and process JSON can use the API to integrate outbound SMS, delivery reports and inbound messages.
Can we receive SMS and delivery reports?
Yes. Webhooks can send inbound SMS and status updates to a URL in your system. Receiving inbound SMS requires a recipient number linked to your account.
