Why am I getting a "client_id invalid" error on the authorization request with the Shopify Customer Account API?

To resolve a "client_id invalid" error on the authorization request with the Shopify Customer Account API, follow these steps:

1.Verify Client ID:

Ensure that the client_id you are using is correct and matches the one provided by Shopify for your app. This is typically found in your Shopify Partner Dashboard under the app's credentials.

2. Check OAuth Configuration:

Verify that your OAuth configuration in Shopify is set up correctly:
Go to your Shopify Partner Dashboard.
Navigate to Apps and select your app.
Check the App credentials section for the correct client_id and client_secret.

3. Update Authorization Request:

Ensure your authorization request includes the correct client_id. Here’s an example of a typical OAuth authorization request:

const clientId = 'your_actual_client_id';
const redirectUri = 'https://yourapp.com/auth/callback';
const scopes = 'read_customers,write_customers';
const state = 'random_state_string';

const authUrl = `https://your-store.myshopify.com/admin/oauth/authorize?client_id=${clientId}&scope=${scopes}&redirect_uri=${redirectUri}&state=${state}`;

// Redirect the user to Shopify for authorization
window.location.href = authUrl;

4.Check Redirect URI:

Make sure that the redirect_uri specified in your request matches one of the redirect URIs registered for your app in the Shopify Partner Dashboard.

5.Ensure Proper App Permissions:

Verify that your app has the required permissions/scopes for accessing customer data. You can update these in the Shopify Partner Dashboard under your app's settings.

6. Review Error Messages:

Check the full error response for additional details. Ensure that the client_id you are using is not expired or incorrect.

7. Regenerate Credentials (if needed):

If you suspect the credentials might be compromised or incorrect, regenerate the client ID and secret in your Shopify Partner Dashboard and update your application configuration accordingly.

8.Test the Authorization Flow:

After making the necessary adjustments, test the OAuth authorization flow again to ensure the "client_id invalid" error is resolved.

By following these steps, you should be able to troubleshoot and resolve the "client_id invalid" error with the Shopify Customer Account API.
