Stripe GraphQL API

This package creates a Stripe GraphQL API, allowing for interaction with data at Stripe.

Here's an example of how to use the Stripe GraphQL API to get a list of invoices for a specific Stripe customer:

query {
  stripe {
    customer(id: "cus_xxx") {
      id
      name
      invoices {
        data {
          id
          created
          paid
          hostedInvoiceUrl
        }
      }
    }
  }
}

It's recommended to add the Stripe GraphQL API as a Remote Schema in Hasura and connect data from your database with data in Stripe. By doing so, it's possible to request data from your database and Stripe in a single GraphQL query.

Here's an example of how to use the Stripe GraphQL API to get a list of invoices for a specific Stripe customer. Note that the user data is fetched from your database and the Stripe customer data is fetched from Stripe:

query {
  users {
    # User in your database
    id
    displayName
    userData {
      stripeCustomerId # Customer's Stripe Customer Id
      stripeCustomer {
        # Data from Stripe
        id
        name
        paymentMethods {
          id
          card {
            brand
            last4
          }
        }
      }
    }
  }
}

Get Started​

Install the package:

npm install @nhost/stripe-graphql-js

Serverless Function​

Create a new Serverless Function: functions/graphql/stripe.ts:

import { createStripeGraphQLServer } from '@nhost/stripe-graphql-js'

const server = createStripeGraphQLServer()

export default server

You can run the Stripe GraphQL API in any Node.js environment because it's built using GraphQL Yoga.

Stripe Secret Key​

Add STRIPE_SECRET_KEY as an environment variable.

If you're using Nhost, add STRIPE_SECRET_KEY to .env.development like this:

STRIPE_SECRET_KEY=sk_test_***

And add the production key (sk_live_***) to environment variables in the Nhost dashboard.

Test​

Test the Stripe GraphQL API in the browser:

Remote Schema​

Add the Stripe GraphQL API as a Remote Schema in Hasura.

URL

{{NHOST_FUNCTIONS_URL}}/graphql/stripe

Headers

x-nhost-webhook-secret: NHOST_WEBHOOK_SECRET (From env var)

The NHOST_WEBHOOK_SECRET is used to verify that the request is coming from Nhost. The environment variable is a system environment variable and is always available.

Hasura Remote Schema

Permissions​

Here's a minimal example without any custom permissions. Only requests using the x-hasura-admin-secret header will work:

const server = createStripeGraphQLServer()

For more granular permissions, you can pass an isAllowed function to the createStripeGraphQLServer. The isAllowed function takes a stripeCustomerId and context as parameters and runs every time the GraphQL server makes a request to Stripe to get or modify data for a specific Stripe customer.

Here is an example of an isAllowed function:

import { createStripeGraphQLServer } from '@nhost/stripe-graphql-js'

const isAllowed = (stripeCustomerId: string, context: Context) => {
  const { isAdmin, userClaims } = context

  // allow all requests if they have a valid `x-hasura-admin-secret`
  if (isAdmin) {
    return true
  }

  // get user id
  const userId = userClaims['x-hasura-user-id']

  // check if the user is signed in
  if (!userId) {
    return false
  }

  // get more user information from the database
  const { user } = await gqlSDK.getUser({
    id: userId
  })

  if (!user) {
    return false
  }

  // check if the user is part of a workspace with the `stripeCustomerId`
  return user.workspaceMembers.some((workspaceMember) => {
    return workspaceMember.workspace.stripeCustomerId === stripeCustomerId
  })
}

const server = createStripeGraphQLServer({ isAllowed })

export default server

Context​

The context object contains:

  • userClaims - verified JWT claims from the user's access token.
  • isAdmin - true if the request was made using a valid x-hasura-admin-secret header.
  • request - Fetch API Request object that represents the incoming HTTP request in platform-independent way. It can be useful for accessing headers to authenticate a user
  • query - the DocumentNode that was parsed from the GraphQL query string
  • operationName - the operation name selected from the incoming query
  • variables - the variables that were defined in the query
  • extensions - the extensions that were received from the client
