New Customer Account API Migration

Follow these steps to migrate from the legacy customer accounts to the new Customer Account API.

This migration is required before integrating the Shopify B2B logic into the codebase.

Migration Caveats:

• The logged in experience will no longer be supported while in the Pack Customizer due to the nature of customer authentication
• Customer accounts doesn't support the use of localhost due to security concerns. In order to use customer accounts while in development, localhost must be hosted on a public URL via ngrok (see below for instructions)
• Multipass is currently not supported, though if a customer is logged in and goes to checkout, logging in will be a one click action

Local Development and Hydrogen Settings

For official Shopify documentation for Customer Account API with Hydrogen, it can be referenced here, but the pertinent steps are re-outlined below.

Set up ngrok

ngrok has a free plan but is limited by the number of HTTP requests that can be made monthly. The free plan may be sufficient to get through this migration, but upgrading to a paid plan may be a likely scenario for the long term maintenance of the store, due to the added convenience to create your own domain and to not be limited by your usage. In later steps, the ngrok domain will need to be added officially into Hydrogen settings.

1. Set up an ngrok account
2. If you have a paid account, add a static domain in your ngrok settings. If you are using the free plan, a random domain is generated for you after every instance as seen in the terminal, e.g. https://abc123def456.ngrok-free.app
3. Install the ngrok CLI
4. In a terminal, start ngrok using the following command:

Paid account: ngrok http --domain=<your-ngrok-domain> 8080

Free account: ngrok http 8080

Notes:

• Working off ngrok is only needed for using customer accounts, all other development can still be viewed on localhost directly
• Stopping or restarting localhost does not kill the ngrok instance
• If you using the free plan and the ngrok instance is stopped, upon starting again, a new random domain will be generated, thus this new domain will need to replaced with the one added in Hydrogen settings

---

Update the application setup

For the Customer Account API to recognize your domain as a valid authentication host, edit your Customer Account API settings.

1. The panel can be found in Storefront settings for the Hydrogen store, then under Customer Account API
2. Under Application setup, click Edit to edit the endpoints
3. Under Callback URI(s), click Add Callback URI, add all the /account/authorize url's prefixed with their domain

• First add https://<your-main-domain>.com/account/authorize, e.g. https://storefront.com/account/authorize
• Next add one with the ngrok domain as in https://<your-ngrok-domain>.app/account/authorize, e.g. https://abc123def456.ngrok-free.app/account/authorize

  If you are using the free ngrok plan, this domain will repeatedly change on every instance, so this value will continually be replaced during development. This is when the paid account will prove convenient.

4. Under JavaScript origin(s), click Add origin, and all your domains

• First add the main domain, e.g. https://storefront.com
• Next add the ngrok domain, e.g. https://abc123def456.ngrok-free.app
  • As mentioned above, this value will likely be replaced out during development if using a free ngrok account

5. Under Logout URI, click Add Logout URI, and all your domains

• First add the main domain, e.g. https://storefront.com
• Next add the ngrok domain, e.g. https://abc123def456.ngrok-free.app
  • As mentioned above, this value will likely be replaced out during development if using a free ngrok account

Code Migration

Most steps will link to part of the Blueprint release that it is in reference to. These steps will require copying these code changes as a guide of what exactly to do.

Required @shopify/hydrogen session.commit() migration:

Only applicable if this migration has not already been implemented. Per migration notes for 2024-07 @shopify/hydrogen, all instances of session.commit() in routes are removed and instead exists only in server.ts. Additional logic is also added into AppSession [commit]

---

Env variables:

Add both PUBLIC_CUSTOMER_ACCOUNT_API_CLIENT_ID and PUBLIC_CUSTOMER_ACCOUNT_API_URL to the .env file, if not already added. The values can be found under the "Ready-only variables" in Hydrogen settings Environment and variables

---

Add Customer Account client:

1. In server.ts, add createCustomerAccountClient and pass customerAccount into getLoadContext [commit]
2. In root.tsx, remove customerAccessToken logic and replace with customerAccount client logic [commit]
3. In remix.env.d.ts or env.d.ts, add new Env and client types [commit]
4. In useCustomer.ts, remove logic pertaining to previewModeCustomer [commit]
5. Create a new file for the new Customer Account API Graphql queries [commit]

• For Blueprint, the new Graphql file exists in a new customer-account folder created under app/data/graphql, but matching this folder structure is not important, rather just ensure all Graphql imports from this file are imported correctly after the migration

---

Customer folder and hooks bulk actions:

1. Delete the entire customer folder in the app/lib folder**
2. Download this customer folder and paste the folder into the app/lib folder
3. For customer hooks, download this customer folder and paste the folder into the app/hooks folder; then add the export to the index.ts file [commit]
4. For the remaining hooks, update the imports from ~/lib/customer to from ~/hooks, e.g. convert import {useCustomerCreateAddress} from '~/lib/customer'; to import {useCustomerCreateAddress} from '~/hooks';

• The hooks include: useCustomerCreateAddress, useCustomerDeleteAddress, useCustomerLogOut, useCustomerUpdateAddress, useCustomerUpdateProfile

Examples include:

• Additional fields queried with Graphql for the customer. Reference the new Customer Account API Customer object to see what Graphql fields are accepted
• Additional hooks or logic added for additional customer integrations

---

Cleanup account components:

1. Delete GuestAccountLayout.tsx from the app/components/AccountLayout folder; then delete its export from the index.ts file [commit]
2. Delete the Login folder, Register folder, Activate.tsx file and ResetPassword.tsx file from the app/components/Account folder; then delete their exports from the index.ts file [commit]
3. In Layout.tsx, remove usePreviewModeCustomerInit() [commit]
4. In CustomerAccountLayout.tsx, customerPending logic can be removed because it is no longer relevant [commit]

---
