Yes, there is a portal so that citizens and companies can consult, create or manage their representations for actions before public administrations.
Access to the portal is via a URL that changes depending on the organization:
https://representa.cat/representa/ciutada?codi=x
x=INE10 code without initial 0 (In the case of non-local organizations, it is the id code of EACAT)
Therefore, there is an instance for each entity registered with the service.
You can consult the list of registered organizations at Representa .
