Hi Zendesk community,
I tried this way (and other ways replacing 'null' by "" and 0 and also with the POST method) to delete the ticket organization but didn't succeeded yet, do you have the answer?

Best regards!

Thank you for reaching out and asking your question in our community. As you mentioned above, the ticket's organization is linked directly to the requester's organization and cannot be changed manually or through API.
In order to remove a ticket from an organization, you will need to remove the requester from the organization as well.
However, you can manage which user's access to the tickets in their organization so that not all the users can see all the tickets in the organization. You can set up a shared organization to allow all end-user's access or you can you can grant this privilege to a select group of end users. To do so, set the org to Can view own tickets only, then set individual users to Can view all org tickets in their user profiles. The user permission in that case overrides the organization-wide setting.
Please, see this article for more information about this: Creating organizations.
All the best!
