What is an SMS API?
A cloud-based SMS service is provided to clients on demand over the internet from the cloud computing provider’s servers (hardware). So, there’s no need for the client to have their own on-premises servers to host and run the software, making for greater ease of use.

How can my business start sending global SMS quickly and reliably?
It's easy! Sinch can help you set it up, and our technical support team is here for you every step of the way.

-
How do I receive SMS message replies?
You’ll need to purchase an inbound SMS number to receive replies. If you already have a Sinch SMS account, please contact customer support or your Account Manager, and we'll help you get this sorted.
-
Why is SMS delivery time important?
For text messages that need to be delivered immediately, you need an SMS service with low latency. Two-factor authentication, banking, or ticketing applications are just some examples of messages where instant delivery is essential to the end user.
How do I know if my messages were delivered?
For every SMS or MMS sent with Sinch’s REST API, we receive information about the message delivery status from the message carriers. This information is then made available to you in our delivery reports for easy analysis and strategy adjustment.
-
Can I send text messages internationally to multiple countries at a time?
Yes, you can! Just make sure that you're using the right country codes when uploading international numbers so that they're routed correctly.
Please be aware that because messages are charged per network and destination, costs may vary on messages sent internationally.
