Note: This article provides information related to the standalone SMS API, and it is being maintained for existing customers only. New customers will access SMS functionality through Sinch's Conversation API. For information on Conversation API endpoints, see our documentation on Conversation API base URLs.

And endpoint is one end of a communication channel for when an API interacts with another platform - the touchpoint of this connection is considered an endpoint. Usually, with an API, an endpoint can include a URL of a server or service. Each endpoint is the location from which APIs can access the resources they need to carry out their function.

The Sinch SMS endpoints are located in different geographical locations for data purposes and are as follows:

General API	https://us.sms.api.sinch.com
US Production	https://us.sms.api.sinch.com
EU Production	https://eu.sms.api.sinch.com
Australian production	https://au.sms.api.sinch.com
Brazil Production	https://br.sms.api.sinch.com
Canada Production	https://ca.sms.api.sinch.com

Please note, you will have the general API endpoint set up unless otherwise specified or requested.

For further reference, refer to the full Sinch SMS API documentation.
