To use most of the APIs you need to register for a key. The APIs for the University and the University of Applied Sciences are available on two different systems that require their own keys. The use of the open data services of Tampere University of Technology does not require these keys.
Credentials for APIs can be applied for by using electronic forms:
When obtaining the credentials, the user also obtains a personal secret API key with which the user is permitted to use the open data interfaces available at the time. It is not allowed to hand the key over to anyone else. Usage description of the application and developer’s contact information are recorded with the key.
