Connector is a core component in Open Celium. It is a system to which we will send requests and get responses. They can be different throw different protocols: HTTP, JSON-RPC, SOAP, and so on. Currently, HTTP and JSON-RPC are available. Connector uses invokers. Invoker is a special file filled in with instructions.

Each item of the connector’s list displays a title and an icon.


Viewing the connector you can read a description of the connector itself and information about invoker to which it was assigned, like: title, description, hint, and operations.


Adding/Updating connector consists of two steps: general data, and credentials. General data step has four input fields: title, description, invoker and icon. The title and invoker are required fields. The icon can be unset setting checkbox as uncheck.


Credentials step has several input fields. We need this step to set up a connection to the system that describes invoker. A type of field depends on the chosen invoker. Different invokers have different authentication systems, that are described inside of the invoker. All fields usually are required. If the invoker has a password field, you can click on the checkbox on the right to see what you are typing instead of asterix. Before adding/updating you test the connection. If it was completed successfully you can finish the process.
