The Store API uses Ransack for filtering and sorting collection endpoints. All query parameters are passed via the q parameter.
Filtering
Pass filter conditions using the q parameter with Ransack predicates:
Common Predicates
| Predicate | Description | SDK | cURL |
|---|
eq | Equals | status_eq: 'active' | q[status_eq]=active |
not_eq | Not equals | status_not_eq: 'draft' | q[status_not_eq]=draft |
cont | Contains (case-insensitive) | name_cont: 'shirt' | q[name_cont]=shirt |
start | Starts with | name_start: 'Spree' | q[name_start]=Spree |
end | Ends with | slug_end: 'tote' | q[slug_end]=tote |
lt | Less than | price_lt: 50 | q[price_lt]=50 |
lteq | Less than or equal | price_lteq: 50 | q[price_lteq]=50 |
gt | Greater than | price_gt: 10 | q[price_gt]=10 |
gteq | Greater than or equal | price_gteq: 10 | q[price_gteq]=10 |
in | In a list | status_in: ['active', 'draft'] | q[status_in][]=active&q[status_in][]=draft |
null | Is null | deleted_at_null: true | q[deleted_at_null]=true |
not_null | Is not null | completed_at_not_null: true | q[completed_at_not_null]=true |
present | Is present (not empty) | description_present: true | q[description_present]=true |
blank | Is blank (null or empty) | description_blank: true | q[description_blank]=true |
true | Is true (boolean) | purchasable_true: 1 | q[purchasable_true]=1 |
false | Is false (boolean) | purchasable_false: 1 | q[purchasable_false]=1 |
The SDK automatically wraps filter keys in q[...] and appends [] for array values — just pass flat params.
Combining Filters
Multiple filters are combined with AND logic:
Filtering by Association
You can filter by associated model attributes using underscore notation:
Product Scopes
Products support additional filter scopes beyond standard Ransack predicates:
| Scope | Description | SDK | cURL |
|---|
price_gte | Minimum price | price_gte: 20 | q[price_gte]=20 |
price_lte | Maximum price | price_lte: 100 | q[price_lte]=100 |
with_option_value_ids | Filter by option value IDs | with_option_value_ids: ['optval_abc'] | q[with_option_value_ids][]=optval_abc |
in_stock | Only in-stock products | in_stock: true | q[in_stock]=true |
out_of_stock | Only out-of-stock products | out_of_stock: true | q[out_of_stock]=true |
search | Full-text search | search: 'shirt' | q[search]=shirt |
Sorting
Use the sort parameter on any list endpoint. Prefix a field with - for descending order (ascending is the default). This follows the JSON:API sorting convention.
Product Sort Options
| Value | Description |
|---|
manual | Manual sort order (default, uses taxon position) |
best_selling | Best selling products first |
price | Price low to high |
-price | Price high to low |
name | Name A-Z |
-name | Name Z-A |
-available_on | Newest first |
available_on | Oldest first |
Sorting Other Resources
The sort parameter works on all list endpoints. Use any sortable column name:
Expanding Associations
Use the expand parameter to include associated resources in the response. Pass a comma-separated list of association names:
Nested Expand
Use dot notation to expand nested associations (up to 4 levels deep):
Rules
- Maximum depth is 4 levels (e.g.,
a.b.c.d)
- A nested expand automatically includes its parent —
expand=variants.media expands both variants and their media
- Nested expand only applies to conditional associations (those controlled by
expand)
Field Selection
Use the fields parameter to request only specific fields in the response. This reduces payload size for bandwidth-sensitive clients like mobile apps or server-side rendering.
Rules
- The
id field is always included, even if not listed in fields
- Omitting
fields returns all fields (default behavior)
- Field selection applies to the top-level resource only — expanded associations always return their full set of fields
- Expanded associations are always included in the response regardless of
fields — ?fields=name&expand=variants returns id, name, and variants
The SDK TypeScript types remain fully typed regardless of field selection. When using fields, be aware that only the requested fields will be present at runtime.
All collection endpoints return paginated results. Control pagination with page and limit parameters:
| Parameter | Default | Max | Description |
|---|
page | 1 | - | Page number |
limit | 25 | 100 | Number of records per page |
Collection responses include a meta object with pagination info:
| Field | Description |
|---|
page | Current page number |
limit | Records per page |
count | Total number of records |
pages | Total number of pages |
from | Starting record number on this page |
to | Ending record number on this page |
in | Number of records returned on this page |
previous | Previous page number (null if first page) |
next | Next page number (null if last page) |
