I am testing the API and I have successfully logged in - I obtained correct cookies and the status in the response is "200 OK". I have tried further requests but I can retrieve only the published information. What is the cause? My account has got the respective rights and the credentials are correct.
Probably you put the credentials directly into the login link. For security reasons Signavio does not allow to login when the credentials are given as link parameter. Please look at the list of returned cookies and find the "identifier". If the value of this cookie is "Hub+user", you have been authenticated only as an "anonymous" hub user. In case of successful authentication the value of "identifier" should be name+surname of your user account. To avoid this, please put the credentials into body of the API request.
