# Look up product details

> Pull product details from an external database by barcode, ISBN, or model.

When a product is missing details, you can look it up in an external database
and pull the values straight into the product editor. Nothing saves to Shopify
until you click **Save**, so you stay in control.

<Steps>
  <Step title="Open the product">
    Open the product in the [editor](/guides/edit-a-product) and find the
    product details card.
  </Step>

  <Step title="Click Look up details">
    Click **Look up details** in the card header. Atlios opens a search box,
    already filled with the product's barcode or SKU when it can.
  </Step>

  <Step title="Search">
    Search by **barcode, ISBN, or model number**. A chip shows which type Atlios
    detected. If there are several matches, pick the right one.
  </Step>

  <Step title="Choose what to use">
    Each found field shows the external value next to your current value. Click
    **Use this** on a field, or **Use all** to take everything that differs.
    Fields that already match are marked **In use**.
  </Step>

  <Step title="Save">
    Review the changes and click **Save** to write them back to Shopify.
  </Step>
</Steps>

## What it can fill

A lookup can bring in the **title**, **vendor (brand)**, **product type**, and
**description**. If the source has an image, use **Use this image** to stage it
into the [Media](/guides/edit-a-product) section; it applies when you save.

Dimensions and weight, when found, are shown under **Also found** for reference.
They are not applied to the product.

## What you can search by

<AccordionGroup>
  <Accordion title="ISBN (books)">
    Book lookups work out of the box using Google Books and Open Library. No
    setup needed.
  </Accordion>

  <Accordion title="Barcode or model number">
    General retail lookups by barcode (GTIN) or model number (MPN) use the
    Barcode Lookup provider, which needs an API key. If no key is configured,
    Atlios tells you, and book lookups by ISBN still work.

<Warning>
  External data can be wrong or out of date. Review every field before you save.
  Atlios never changes the product on its own; the lookup only suggests values.
