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 through a URL that changes depending on the entity and which is:
https://representa.cat/representa/ciutada?codi=x
x=codI INE10 without initial 0
Therefore, there is one instance for each user registered with the service.
You can consult the list of registered entities in Representa at: Registered entities in Representa
