Hi there, you can use Stripe's customerID to map with your customers in your own DB.

vagrant nebula Feb 21, 2023, 5:08 AM

#

Hi, so I have done that already I think. I have used Auth0 Actions which creates a a Stripe Customer ID and adds it to my Auth0 users app_metadata added to the Login Flow but I am having a hell of a time figuring out how to use it to add roles to the app_metadata based on the customers purchases.

pearl osprey Feb 21, 2023, 5:10 AM

#

So it's more a question on how your application handle the Auth instead of payments?

vagrant nebula Feb 21, 2023, 5:16 AM

#

Well ideally I would want it to set the roles after Stripe checkout is completed but I tried that first and I was able to get it to the point where I could complete checkout for a product and it would return me to the /success page and say everything was successful and it even added the customer in Stripe but no matter what I tried I could not get it to set the roles. I was calling a Netlify Function in the code for the success page. Was that a better approach?

#

Any way it can be accomplished I am cool with at this point lol

pearl osprey Feb 21, 2023, 5:20 AM

#

So you only want to set the role on customer (I assume the role is enable paid customer to enjoy your service) when the first invoice of the subscription is paid successfully?

vagrant nebula Feb 21, 2023, 5:21 AM

#

Yeah pretty much.

#

Here is a function I created for returning the Role name based on the product's price id...
// Get role name from product ID
function getRoleFromPlan(planId) {
switch (planId) {
case 'price_1LAIw9FUDFxTEzZGYzM290b6':
return 'Free Member';
case 'price_1LAIzgFUDFxTEzZGIhVayoGC':
case 'price_1MbqhmFUDFxTEzZGSxfA0Ed5':
return 'Epic Member';
case 'price_1LAJ0tFUDFxTEzZGaNqoqBqi':
case 'price_1MbqiVFUDFxTEzZGo87RhTHT':
return 'Legendary Member';
default:
return null;
}
}

OK. I'll suggest you to listen to webhook event invoice.paid, which is fired when a invoice is paid successfully.

vagrant nebula Feb 21, 2023, 5:24 AM

#

Okay thanks but I tried using a webhook once too and it was very confusing to me. Do you have a example of how to use a webhook to do something like this you can link me to or something?

#

Perfect thanks a bunch!

vagrant nebula Feb 21, 2023, 6:23 AM

#

Is this correct? And will it trigger automatically whenever stripe receives an invoice.paid event, I don't need to call it in my code anywhere?

#

My code for the handle-subscription-change function is...

const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);
const ManagementClient = require('auth0').ManagementClient;

// Set up the Auth0 Management API client
const auth0 = new ManagementClient({
  domain: process.env.AUTH0_DOMAIN,
  clientId: process.env.AUTH0_API_EXPLORER_CLIENT_ID,
  clientSecret: process.env.AUTH0_API_EXPLORER_CLIENT_SECRET,
  audience: `https://${process.env.AUTH0_DOMAIN}/api/v2/`,
});

// Get role name from product ID
function getRoleFromPlan(planId) {
  switch (planId) {
    case 'price_1LAIw9FUDFxTEzZGYzM290b6':
      return 'Free Member';
    case 'price_1LAIzgFUDFxTEzZGIhVayoGC':
    case 'price_1MbqhmFUDFxTEzZGSxfA0Ed5':
      return 'Epic Member';
    case 'price_1LAJ0tFUDFxTEzZGaNqoqBqi':
    case 'price_1MbqiVFUDFxTEzZGo87RhTHT':
      return 'Legendary Member';
    default:
      return null;
  }
}

exports.handler = async (event) => {
  const sig = event.headers['stripe-signature'];
  let eventObject;

  try {
    eventObject = stripe.webhooks.constructEvent(event.body, sig, 'whsec_MKxjsjSYqz5MdmetrTCbupmAQD2hFxpX');
  } catch (err) {
    return { statusCode: 400, body: `Webhook Error: ${err.message}` };
  }

  if (eventObject.type === 'customer.subscription.updated') {
    const subscription = eventObject.data.object;
    const userId = subscription.metadata.userId;

    // Update user role in Auth0 based on subscription status and price ID
    const isSubscriptionActive = subscription.status === 'active';
    const role = isSubscriptionActive ? getRoleFromPlan(subscription.items.data[0].price.id) : 'Free Member';

    try {
      await auth0.updateUserMetadata({ id: userId }, { app_metadata: { role } });
      return { statusCode: 200, body: 'Webhook received successfully' };
    } catch (error) {
      console.error(error);
      return { statusCode: 500, body: 'Error updating user role in Auth0' };
    }
  }

  return { statusCode: 200, body: 'Webhook received successfully' };
};

I don't see invoice.paid being handled in your code,

vagrant nebula Feb 21, 2023, 6:28 AM

#

I thought that selecting it when setting up the webhook was all that was needed.

pearl osprey Feb 21, 2023, 6:32 AM

#

No, you still need to handle the event in your own code.

vagrant nebula Feb 21, 2023, 6:32 AM

#

Good to know, thanks!

Do free subscriptions also trigger the invoice.paid event? I want to test checking out with my Free Subscription to see if it assigns me the Free Member role.

pearl osprey Feb 21, 2023, 6:44 AM

#

nitpick: invoice.subscription may be null because invoice.paid is also fired for one-off invoice (i.e., not generated by subscription)

vagrant nebula Feb 21, 2023, 6:46 AM

#

Oh I see what you mean now, thanks...

    let subscription;
    if (invoice.subscription) {
      subscription = invoice.subscription;
    }

pearl osprey Feb 21, 2023, 6:47 AM

#

By free subscription you mean subscription with trial? Yes an invoice.paid event will be fired for the first $0 invoice as well

vagrant nebula Feb 21, 2023, 6:48 AM

#

No I mean just a subscription that cost nothing...

pearl osprey Feb 21, 2023, 6:52 AM

#

Yes, an invoice.paid event will be fired.

vagrant nebula Feb 21, 2023, 6:52 AM

#

Hmmm so not sure what I did wrong then.

#

#

Guess it is Auth0 related. Hmmm

pearl osprey Feb 21, 2023, 6:57 AM

#

Your server returns 500, which means server error. You should check your server log and investigate the problem

vagrant nebula Feb 21, 2023, 7:01 AM

#

My Netlify Logs for the function?

#

Ahh yeah I see some clues in there. One more thing real quick...
When I click on the customer I made completed checkout for the Free Membership with, I saw the webhook icon but when I clicked it it has the wrong function name it has the name I used last time I tried using a webhook. Where do I change that?

pearl osprey Feb 21, 2023, 7:05 AM

#

What do you mean by wrong function name? this is the webhook URL that you configured in the webhook settings page https://dashboard.stripe.com/webhooks

Stripe Login | Sign in to the Stripe Dashboard

vagrant nebula Feb 21, 2023, 7:06 AM

#

I mean that the function I just wrote is named handle-subscription-change not stripe-webhook

pearl osprey Feb 21, 2023, 7:07 AM

#

That function name is internal to you, you can change to whatever you want as long as the URL that you specify for webhook endpoint is valid.
