Beware that Sandbox mode is only available for the REST API.
A sandbox system is available to you for testing. The sandbox will not m= odify your account in any way, but will respond normally to your reque= sts. In other words if you use the sandbox to get the number of credits on = your account, it will provide the correct number.
However if you use it to transfer credits between accounts, it will simu= late a successful transfer (assuming you have enough credits on the account= , and provide valid target account details, etc.) but it will not actually = modify the number of credits on either account.
Similarly, the sandbox system will not actually send SMS messages and wi= ll not deduct credits for simulated sends.
The sandbox system is available at the URL:
http://sandbox.textmarketer.biz/s= ervices/rest/
=20
i.e. to use the sandbox simply replace this part of the resource URL:
api= .textmarketer.co.uk
=20
With this:
san= dbox.textmarketer.biz
=20
For example, the credits resource URL becomes:
http://sandbox.t= extmarketer.biz/services/rest/credits
=20
The sandbox is restricted to a certain number of requests per minute. So= you should not use it to test bulk SMS sends. This to reduce load on our s= ervers, in order to guarantee a good service to all our users. There is no = restriction on SMS sends onthe live system.
