How can this Bulk Update Inventory with Shopify API template benefit my e-commerce business?
The Bulk Update Inventory with Shopify API template can significantly streamline your inventory management process. It allows you to update inventory levels for multiple products simultaneously, saving time and reducing errors compared to manual updates. This is particularly beneficial for businesses with large product catalogs or those that frequently need to adjust inventory across multiple locations.
Can I use this template to sync inventory between my Shopify store and a third-party warehouse management system?
Yes, the Bulk Update Inventory with Shopify API template is ideal for integrating with external systems. You can use the /bulk_update_inventory endpoint to push inventory updates from your warehouse management system to Shopify, ensuring your online store always reflects accurate stock levels. Similarly, the /fetch_inventory_levels endpoint can be used to retrieve current inventory data from Shopify for reconciliation with your external system.
Is there a limit to how many inventory items I can update at once using this template?
While the Bulk Update Inventory with Shopify API template itself doesn't impose a strict limit, it's important to consider Shopify's API rate limits. The template uses Shopify's bulk mutation, which is more efficient than individual updates. However, it's recommended to keep your updates to a reasonable number (e.g., a few hundred items) per request to ensure optimal performance and avoid hitting API limits.
How can I modify the template to include additional product information when fetching inventory levels?
You can extend the FETCH_INVENTORY_QUERY in the Bulk Update Inventory with Shopify API template to include additional fields. For example, to include the product title and variant title, you could modify the query like this:
python
FETCH_INVENTORY_QUERY = gql("""
query fetchInventoryLevels($locationId: ID!) {
location(id: $locationId) {
id
inventoryLevels(first: 250) {
edges {
node {
id
item {
id
sku
variant {
title
product {
title
}
}
}
available
}
}
}
}
}
""")
This modification will include the product title and variant title in the response from the /fetch_inventory_levels endpoint.
How can I add error handling for individual item updates in the bulk update process?
To add error handling for individual items in the Bulk Update Inventory with Shopify API template, you can modify the bulkUpdateInventory function to process the response and check for errors. Here's an example of how you could do this:
```python @app.post("/bulk_update_inventory") async def bulk_update_inventory(data: BulkInventoryUpdateData): # ... (existing setup code)
try:
response = client.execute(BULK_UPDATE_MUTATION, variable_values={
"locationId": data.location_id,
"inventoryItems": inventory_items
})
# Process the response
results = []
for level in response['inventoryBulkAdjustQuantityAtLocation']['inventoryLevels']:
item_id = level['id']
available = level['available']
success = available is not None
results.append({
'id': item_id,
'success': success,
'available': available if success else None,
'error': 'Failed to update' if not success else None
})
return {'results': results}
except Exception as e:
raise HTTPException(status_code=500, detail=str(e))
```
This modification will return a detailed response for each item in the bulk update, including whether the update was successful and the new available quantity or an error message if the update failed.

Introduction to the Bulk Update Inventory with Shopify API Template
Welcome to the Bulk Update Inventory with Shopify API template! This template is designed to help you integrate with the Shopify API to manage inventory levels efficiently. With this template, you can quickly set up an application that allows you to bulk update inventory levels and fetch current inventory statuses for products in a Shopify store. This is particularly useful for store owners or developers looking to automate inventory management tasks.
Getting Started
To begin using this template, click on "Start with this Template" in the Lazy platform. This will pre-populate the code in the Lazy Builder interface, so you won't need to copy or paste any code manually.
Initial Setup
Before you can test and use the application, you need to set up an environment secret that the application requires:
SHOPIFY_ADMIN_API_TOKEN: This is the Shopify admin API token used for authenticating requests to the Shopify GraphQL API.
To obtain your Shopify admin API token, follow these steps:
- Log in to your Shopify admin dashboard.
- Go to "Apps" and then click on "Manage private apps" (if you haven't created one, you will need to create a new private app).
- In the private app settings, ensure that you have the necessary permissions to adjust inventory levels.
- After setting the permissions, you will see the API token generated for your app. Copy this token.
Once you have your Shopify admin API token, go to the Environment Secrets tab within the Lazy Builder and add a new secret with the key SHOPIFY_ADMIN_API_TOKEN and paste the token you copied as the value.
Test: Pressing the Test Button
After setting up the environment secret, you can press the "Test" button in the Lazy platform. This will begin the deployment of the app and launch the Lazy CLI.
Entering Input
Once the app is deployed, if the code requires user input, the Lazy CLI will prompt you to provide the necessary information. For this template, you will need to input the store URL and location ID when prompted by the CLI.
Using the App
After deployment, Lazy will provide you with a dedicated server link to use the API. Additionally, since this template uses FastAPI, you will also receive a link to the API documentation, which you can use to interact with the endpoints provided by the application:
/bulk_update_inventory: A POST endpoint that allows you to send a JSON payload with the store URL, location ID, and a list of inventory updates to bulk update inventory levels./fetch_inventory_levels: A GET endpoint that retrieves the inventory levels for a specific location in a Shopify store, requiring the store URL and location ID as query parameters.
Here is an example of how to make a request to the /bulk_update_inventory endpoint:
`POST /bulk_update_inventory
Content-Type: application/json
{
"store_url": "your-shopify-store.myshopify.com",
"location_id": "gid://shopify/Location/123456789",
"updates": [
{
"inventory_item_id": "gid://shopify/InventoryItem/987654321",
"available_delta": 10
}
]
}`
And you should expect a response similar to this:
{
"inventoryLevels": [
{
"id": "gid://shopify/InventoryLevel/123456789",
"available": 110
}
]
}
Integrating the App
If you wish to integrate this app with other tools or services, you may need to use the server link provided by Lazy to set up webhooks or API calls from those external tools. Ensure that you have the correct permissions and scopes set up in Shopify to allow for inventory updates.
For example, if you're using a third-party inventory management tool, you might need to add the server link as an endpoint in that tool's settings, allowing it to send inventory update requests to your Lazy app.
By following these steps, you should be able to set up and use the Bulk Update Inventory with Shopify API template on the Lazy platform to manage your Shopify store's inventory levels efficiently.
