Using Stripe webhooks with graphql-yoga and Prisma - express

Question

I'm having some trouble finding how to intercept Stripe webhook calls in my application. I use graphql-yoga (express) and prisma.
I have to listen to payment failure calls from Stripe so I can edit the corresponding user profile.
Thanks for the help!
Stripe webhook calls look like so :
{
"created": 1326853478,
"id": "charge.expired_00000000000000",
"type": "charge.expired",
"object": "event",
"request": null,
"pending_webhooks": 1,
"data": {
"object": {
"id": "ch_00000000000000",
"object": "charge",
"amount": 100,
"captured": false,
"created": 1537153592,
"currency": "usd",
"customer": null,
"description": "My First Test Charge (created for API docs)",
"invoice": null,
"livemode": false,
"on_behalf_of": null,
"order": null,
"outcome": null,
"paid": true,
"receipt_email": null,
"receipt_number": null,
"refunded": false,
"review": null,
"shipping": null,
"source": {
"id": "card_00000000000000",
"object": "card",
"address_city": null,
"address_country": null,
"address_line1": null,
"address_line1_check": null,
"address_line2": null,
"address_state": null,
"address_zip": "12919",
"address_zip_check": "pass",
"brand": "Visa",
"country": "US",
"customer": "cus_00000000000000",
"cvc_check": null,
"name": null,
"tokenization_method": null
},
"statement_descriptor": null,
"status": "succeeded",
}
}
}

Since Stripe Webhook returns a generic http POST with JSON payload, it will not format the event data according to Graphql language query.
For now, what you can do is to expose a normal REST API endpoint using Graphql-Yoga's express[0]
I have composed a working sample code you can try it out
const { GraphQLServer } = require('graphql-yoga')
const typeDefs = `
type Query {
hello(name: String): String!
}
`
const resolvers = {
Query: {
hello: (_, { name }) => `Hello ${name || 'World'}`,
},
}
const server = new GraphQLServer({ typeDefs, resolvers, skipValidation: true })
server.express.use('/api/stripe/webhooks', (req, res) => {
// Handle your callback here !!!!
res.status(200).send();
})
server.start(() => console.log('Server is running on localhost:4000'))
Let me know if the above helps.
