In order to connect a service to the Open Charging Network, the first thing you need to do is to decide which OCN Node you want to connect to. You want to know the OCN-Identity (wallet address) from your OCN-Node Operator and you need to request a registration token (TOKEN_A in OCPI terms). Note that this token is only temporary and will become invalid once the registration is complete.
Get the required information of your selected OCN Node:
If you want to connect to one of the public nodes of the Public Test Network, please visit this page to obtain the OCN-Identity and a registration token: Connecting a service (Test Network)
If you want to connect to on of the public nodes of the Production Network, please visit this page to obtain the OCN-Identity and a registration token: Connecting a Service (Production Network)
Enter details in OCN-Registry
After receiving this information, you are now ready to create / update your OCN-Identity on the OCN-Registry. Please follow the steps provided here: https://shareandcharge.atlassian.net/wiki/spaces/OCN/pages/edit-v2/331677740?draftShareId=22bf1fb3-22c1-491d-af74-711f3fdb0da6.
