On 22 May 2014 the deployment to production of SL’s new APIs begins: SL Platsuppslag, SL Störningsinformation 2, SL Trafikläget 2 and SL Realtidsinformation 3. During this time you will not be able to use the APIs. We will get back to you when they are ready for use. We hope this will happen within a week.
