Yes — if you use an SMS API, you can usually receive replies as well as send messages.
How it typically works:
- You send an SMS from your app through the API.
- The recipient replies to that number.
- Your SMS provider forwards the incoming message to your app, usually via a webhook or callback URL.
What you need:
- An SMS provider that supports two-way messaging
- A phone number capable of receiving inbound SMS
- A webhook endpoint in your app to handle incoming messages
Things to check:
- Whether the provider supports inbound SMS in your country/region
- Whether short codes, toll-free numbers, or long codes are required
- Whether the number is shared, dedicated, or verified
- Any messaging compliance requirements
If you want, I can also show you:
- a basic inbound SMS flow, or
- example code for receiving replies with a specific provider like Twilio, Vonage, or AWS SNS.
