Browse API: Browse Collection Page

Authorization

X-Storefront-Access-Token

string

required

Token-based authentication header in the form of <YOUR_LAYERS_TOKEN>.

Headers

Content-Type

string

default:"application/json"

required

string

default:"application/json"

required

Path parameters

collection_handle

string

required

The handle of the collection you wish to browse.

Body

sort_order_code

string

Code of the sort order. If omitted, the collection’s default sort order will be used (configured via the Layers dashboard or the layers.default_sort_order metafield on the collection).

dynamicLinking

object

Dynamic Linking allows you to promote specific products to the top of the first page of results. This feature takes priority over merchandising rules and sort orders.

If the Layers tracking pixel is installed, this parameter is automatically injected when customers arrive with a utm_products URL parameter (e.g., ?utm_products=summer-dress-blue_classic-tee-white_beach-hat). See Dynamic Linking for ads for details.

Show Properties

products

array

required

Array of product identifiers (handles or IDs) in the order you want them to appear. The first item will be position 1, second item position 2, etc.

Handles: String values (e.g., "summer-dress-blue")
IDs: Numeric values (e.g., 8234567890123)
Mixed: You can combine both handles and IDs in the same array

Behavior:

Only applies on the first page of results (page 1)
Non-existent or unavailable products are silently skipped
Subsequent products shift up to fill any gaps
Takes priority over merchandising rules and sort orders

Example:

{
  "dynamicLinking": {
    "products": ["summer-dress-blue", 8234567890123, "classic-tee-white"]
  }
}

defaultSelectedOptions

array

Specify which product variants should be selected by default in the first_or_matched_variant field. This is useful for scenarios like defaulting to a specific birthstone option in a jewelry collection.

Show Properties

optionCode

string

required

The product option code to match (e.g., "birthstone", "color"). Option codes are automatically normalized (e.g., "Birth Stone" becomes "birth_stone").

value

string

required

The option value to match (e.g., "February", "Blue").

Behavior:

Uses OR logic - selects the first variant matching ANY of the specified option values
Falls back to the first variant by position if no match is found
Automatically skipped when any option or variant filters are applied (filters take precedence)
Only affects the first_or_matched_variant field in the response
Works with Variant Breakouts - product tiles respect your default selected options, and variant tiles respect non-breakout default selected options (preferring variants that match your preferences within each breakout group, with fallback to position ordering)

Example:

{
  "defaultSelectedOptions": [
    {
      "optionCode": "birthstone",
      "value": "February"
    }
  ]
}

Multiple options example (OR logic):

{
  "defaultSelectedOptions": [
    {
      "optionCode": "birthstone",
      "value": "February"
    },
    {
      "optionCode": "birthstone",
      "value": "March"
    }
  ]
}

This will select variants with either February OR March birthstone, preferring the first match found.

attributes

string[]

Product attributes to include in the response. By default, all attributes are included. Available attributes include: id, title, handle, body_html, vendor, product_type, tags, images, available, created_at, updated_at, published_at, price_range, options, original_options, metafields, named_tags, calculated, category, featured_media, is_gift_card, has_variants_that_require_components, combined_listing_parent_product_id, combined_listing_role, first_or_matched_variant, and variants. See the Product Schema for detailed descriptions.

Refer to our dedicated Filter Expressions guide to learn more about filter expressions.

pagination

Pagination Object

Show pagination

page

int

The current page of results to fetch.

limit

int

facets

string[]

Facets to be included. Accepts both exact facet codes (e.g., "vendor", "options.Size") and wildcard patterns (e.g., "options.*", "metafields.product.*").Wildcard patterns expand to all matching attribute codes. For example, "options.*" expands to all option facets like "options.Size" and "options.Color". Wildcards must match at least one attribute code to be valid.Examples:

// Exact facet codes
"facets": ["vendor", "options.Size", "options.Color"]

// Wildcard pattern
"facets": ["options.*"]

// Mixed exact and wildcard
"facets": ["vendor", "options.*", "metafields.product.*"]

retrieveFacetCount

boolean

If the count of each facet value should be calculated

includeFacetRanges

boolean

If you want a min/max range for numeric facets such as price.

string[]

Array of product IDs or handles that qualify for the discount.

variants

string[] | number[]

Array of variant IDs that qualify for the discount.

collections

string[]

Array of collection handles that qualify for the discount.

discount

object

required

Defines the discount to apply.

Show discount

type

string

required

The discount type: PERCENTAGE or FIXED_AMOUNT.

value

number

required

The discount value. For PERCENTAGE, this must be a number between 0 and 100 (e.g., 10 for 10% off). For FIXED_AMOUNT, this is the currency amount.

identity

object

User identity information for tracking and personalization. Automatically managed by the Storefront Pixel; required for headless integrations.

Show Properties

deviceId

string

Persistent browser identifier that remains constant across sessions. Used to recognize returning visitors for long-term personalization. Automatically generated and managed by the Storefront Pixel.

sessionId

string

Temporary session identifier. Typically corresponds to the Shopify session ID and expires after inactivity or when the browser is closed.

customerId

string

Shopify customer ID for authenticated users. Only present when the user is signed in to their account.

preview_id

string

When provided, the Browse API loads the specified preview rule instead of the collection’s active merchandising rule. Preview rules are temporary and expire one hour after creation.This parameter is automatically included when you open a preview URL from the Layers dashboard. You do not need to set it manually in production integrations.Behavior:

Overrides normal merchandising rule resolution for this request
Analytics and beacon events are not recorded for preview requests
Returns a 404 if the preview has expired or does not exist

forceHideOutOfStock

boolean

default:"false"

When set to true, products with no available variants are excluded from results regardless of the store-level out-of-stock visibility setting. If your store has location-based stock checking configured, the same location rules apply.This is useful when a specific browse integration or page requires strict in-stock filtering even though the store default allows out-of-stock products to appear.

Store-level out-of-stock demoting (the “At the end” option) does not apply to browse results. Browse relies on the Shopify collection itself for product ordering. When you set forceHideOutOfStock to true on a browse request, out-of-stock products are hidden entirely rather than demoted.

weight

number

The boost weight applied. Promotion weights range from 0 to 1.2, where higher values indicate stronger preferences. Demotion weights are small negative values proportional to the strongest promotion in the same attribute group. Option-level attributes (e.g., options.Size) receive lower weights than product-level attributes (e.g., vendor).

"ranking-rules" — Ranking rules influenced result ordering.

See the Text Search documentation for a full list of possible step types.

payload

string | array | object

The data associated with this processing step. The structure varies by type.

Response headers

Every API response includes the following headers for request tracing and performance optimization:

Header	Description
`x-request-id`	A unique identifier (ULID) for the request. This matches the `attributionToken` in the response body. Use it to correlate requests across your infrastructure or when contacting support.
`x-layers-build`	The Layers build version that served the request.
`X-Layers-Results-Cache`	Indicates whether the response was served from the results cache. Returns `HIT` when cached results were used, or `MISS` when results were computed fresh.
`Link`	Contains `rel="preload"` directives for product images in the response (up to 6 items), enabling browsers and CDNs to begin fetching images before your application processes the JSON body. See Early hints for configuration options. Only included when early hints are enabled (enabled by default).

Variant breakouts

When variant breakouts are configured, results may include both product tiles and variant tiles. Each result includes a __typename field to identify the tile type:

__typename

string

Identifies the type of tile in the results:

"Product" - A standard product tile
"Variant" - An individual variant tile from a product with a configured breakout option

Variant tile fields

Variant tiles include additional fields to identify the specific variant:

product_id

number

The parent product ID. Use this to link back to the full product or group variants from the same product.

variant_id

number

The specific variant ID. For variant tiles, this matches the id field.

For variant tiles, the id field contains the variant ID (not the product ID). The title field is formatted as "{product title} - {option value}" by default (e.g., “Amethyst Ring - Rose Quartz”), but this can be configured per breakout. If the breakout’s “Include Option Value in Title” setting is disabled, the title will be the original product title. See the Variant Breakouts documentation for more details.
