The API production and pre-production (sandbox) environments are distinct. This means your pre-production environment's client id, secret and input parameters will not work in the production environment.
If you're ready to move to the production environment, see the "Moving to the production environment" chapter in the Get Started Guide or the FAQs and Troubleshooting section.
If you're experiencing issues with your production environment's client ID, secret, and input parameters, tell the Vodafone support desk, and we'll fix them.
