I am building a create-react-app using Firebase and react-router. I would like to integrate Stripe as payment service provider.

As part of the Stripe verification process, I need to provide the IP address of the user agreeing to the Terms and Conditions, as per the Stipe docs:

stripe.accounts.update(
  {CONNECTED_STRIPE_ACCOUNT_ID},
  {
    tos_acceptance: {
      date: Math.floor(Date.now() / 1000),
      ip: request.connection.remoteAddress // Assumes you're not using a proxy
    }
  }
});

Because I am using a combination of Firebase and react-router, I does not seem like I can use an Express like (req, res) to get the IP in the backend: I dont think I could link the IP address obtained to the user uid. Also when trying to use the ipify of this world on the client with react, I always end up with the same IP in production (no matter the device or location):

import http from 'http';
componentDidMount () {
    http.get({'host': 'api.ipify.org', 'port': 80, 'path': '/'}, function(resp) {
      resp.on('data', ip => {
        alert("My public IP address is: " + ip);
      });
    });
  }

Any idea how I could retrieve the user's IP address either through Firebase Cloud Functions or directly from the client?

Thanks

You can retrieve client IP address using Firebase Cloud Functions. HTTP Triggered Cloud Functions works similar to Node/Express app and they trigger with response and request parameters.

Example

exports.someFunctionName = functions.https.onRequest((req, res) => {
  // ...
});

With that in mind you can implement your Stripe logic in this function.

exports.someFunctionName = functions.https.onRequest((request, response) = > {
    // ...
    stripe.accounts.update({
        CONNECTED_STRIPE_ACCOUNT_ID
      }, {
        tos_acceptance: {
          date: Math.floor(Date.now() / 1000),
          ip: request.ip // Assumes you're not using a proxy
        }
      }
    });
});

  • I have tried this with Cloud Functions, but how can I then link the request to a specific user (be it stripe ID or uid), since I cannot pass any parameter to the "someFunctionName" http trigger? – Freddy Jabali Oct 10 '17 at 09:43
  • You can pass any parameter to Http Functions with GET/POST parameters. For more info read [`fetch` documentation](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) – bennygenel Oct 10 '17 at 09:47
  • @bennygenel Can I do do `onCreate` inside the https request? – Tarvo Mäesepp Dec 23 '19 at 12:53
