Creating a Connection With API​

The creation of a connection establishes a unidirectional messaging transport link to the cloud provider.

To do this, you need to use the Connections group resource:

  • POST/connections to create a new Connection instance
  • PUT/connections to update a Connection instance
  • DELETE/connections to delete a Connection instance
Note

We follow the REST-full API pattern, when updating configuration properties for a connection resource. Thus, you must also provide the whole configuration again.

Example for creation of a new connection instance :

POST /connections
{
  "name":"Actility To Google",
  "connectorId":"actility-google-iot",
  "configuration": {
      "serviceAccount": {your json file},
      "cloudRegion": "us-central1"
  },
}

The following table lists the properties applicable to a connection instance.
