MethodAdapter - Difference between uri and id

[mosoriob]

What is the difference between workflow id and url?

    @Override
    public String getWorkflowId(String id) {
        // Auto-generated method stub
        return this.getEndpointUrl() + "/api/workflows/" + id;
    }

    @Override
    public String getWorkflowUri(String id) {
        // Auto-generated method stub
        return this.getEndpointUrl() + "/api/workflows/" + id;
    }
