An organization is an organizational element that brings together APIs and users. When registering in PISTE, the developer must choose one of the available public organizations or to provide an organization code issued by a organization's administrator.
By default, an API developer who registers on PISTE is assigned to the Universal organization. The API catalog page in the HELP menu sees you all the APIs available on the Universal organization. If you need a API only available on another one, choose this organization. To acces some organizations you must get a organanisation code.To acces some organizations you must get a specific code.
If you are already registered and you want to use an API from another organization than yours, you can contact the PISTE support with the contact form provided for that purpose choosing the subject API Access : Change organization.
