Hi Geoff Lo,

if you are using CSR or SSR extension you have following ways to grab URL params

using tecton grab query paramater from html code and send to Q2 extension's route:

  tecton.sources?.paramsChanged((newParams: any) => {
    console.log(newParams, 'newParams');
    cdRenewalExtension = newParams?.access_key;
  });

in python:
self.get_argument('code', None)

Thanks,
