Saved data and protection of data

See our data protection declaration.


The service is a REST-API over https. The modelling scenario is described by uploading a configuration file (see section configuration file) by the POST Method of the HTTP-protocol. The service is hosted on one or more servers on Port 8000 with the endpoint migrasim. To use the API the easiest simple way is a command line tool like curl or wget. If the configuration file is called migraSIM_Project.json the call is for example:

curl -u [username]:[password] -H "Content-type: application/json" -X POST https://[migrasim-server]:8000/migrasim --data-binary @migraSIM_Project.json

The authentification is done over HTTP Basic authentication. The connection is secured by TLS/SSL with a let’s encrypt certificate. The SAFE+ Algorithmics GmbH will tell the current server name with username, password and certificates for access.
