eCW requires you to set up an endpoint that responds with a JWKS signing public key. See Set up a JWKS Signing Key for an example for how to set this up. The server should respond with the key, formatted like the example below.

You will need to provide the link to this endpoint in the final step of the app creation.

eCW must approve your app and whitelist your JWKS endpoint, as well as add sample data to your sandbox.

To start this process, contact eCW support with your app name, and JWKS signing URL.

Copy your Client ID from the Sandbox Configuration Information page of your registered app, as well as the Kid value of your JWKS. These values will be required to use the eCW Adapter.
