The sandbox mode allows you to send outbound messages to test the integration with the service. There are no sandbox modes for incoming messages.
This mode has separate credits, the size of which depends on your purchased message package. Usually, this limit is 3-4 times less than your main volume of purchased messages from a package.

Messages sent within the Sandbox will always contain technical information at the end of each message.
The sandbox is designed to help your developers or QA team not use the main request limit for which you pay. This also will help you solve the issue when need to send messages separately only for testing and separately use them in a production environment.

Don't use sandbox messaging in a production environment. If you will abuse it, we reserve the right to nullify your sandbox limit.

To send sandbox messages, check our API documentation with instructions on how you can send messages in this environment.
