# Create Attribute Set Creates a new attribute set for the tenant from the supplied name and optional Product and Variant form layouts, returning the created attribute set and a Location header pointing to it. The Product and Variant layouts behave differently when omitted: an omitted productLayout falls back to a standard default layout, whereas an omitted variantLayout is not created at all (no Variant layout is stored). A Variant layout can be added later with PATCH /v2/AttributeSets({id}). ## Authentication Requires a valid API key in the X-API-KEY header. ## Request Body | Field | Required | Description | |---|---|---| | name | ✅ Yes | Unique name for the attribute set within the tenant. | | productLayout | ❌ No | Form layout for Products. Defaults to the standard layout when omitted. | | variantLayout | ❌ No | Form layout for Variants. When omitted, no Variant layout is created (it can be added later via PATCH). | ## Layout Structure Each layout is a JSON document with a sections array. Each section has a title and a rows array. Each row has a fields array and an optional divider (dividerType, dividerTitle). Each field carries an attributeId and a size. json { "sections": [ { "title": "General", "rows": [ { "fields": [ { "attributeId": "prod_title", "size": "half" }, { "attributeId": "prod_ref", "size": "half" } ] }, { "dividerType": "normal", "dividerTitle": "Details", "fields": [ { "attributeId": "prod_description", "size": "row" } ] } ] } ] } size — width of the field in the form grid. One of: quarter, half, threeQuarters, row. dividerType — optional visual separator above the row. One of: normal, wide, lineBreak. dividerTitle is optional and only meaningful when dividerType is set. Both properties are omitted from rows that have no divider. ## Layout Validation A layout may contain any subset of the tenant's valid attributes — you do not need to include all of them. Attributes omitted from the layout simply do not appear in the form for this attribute set; they are not removed from the tenant. If a layout is supplied it must satisfy all of the following rules; otherwise the request returns 400 Bad Request describing each failure: - Every attributeId included must exist for the entity type (Products or Variants) in the tenant's storage definition. - No attributeId may appear more than once across the entire layout. - Each field size must be one of: quarter, half, threeQuarters, row. - The sum of field sizes within any single row must not exceed a full row. - Every row must contain at least one field. - Section title values must be unique (case-insensitive). - When a row sets dividerType it must be one of: normal, wide, lineBreak. ### Required attributes These attributes must always be present in their respective layout: | Layout | Required attribute IDs | |---|---| | productLayout | typ_id, prod_ref, prod_title, cat_ref, prod_stat, prod_description, prod_image, prod_tags | | variantLayout | frmt_stat, prod_ref, frmt_ref, frmt_tags | ## Response 201 Created — The Location header points to the new resource: /v2/AttributeSets({id}). The response body contains the created attribute set (CreateAttributeSet2Response). ## Error Responses - 400 Bad Request — Missing body, missing name, duplicate name, or layout validation failure. - 401 Unauthorized — Missing or invalid tenant identifier. - 500 Internal Server Error — Unexpected technical error. ## Example Request: http POST /v2/AttributeSets HTTP/1.1 X-API-KEY: your-api-key-here Content-Type: application/json { "name": "Electronics" } Response: http HTTP/1.1 201 Created Location: /v2/AttributeSets(7) Endpoint: POST /v2/AttributeSets Version: 2.0.0 ## Request fields (application/json): - `name` (string,null) - `productLayout` (object) Example: {"sections":[{"title":"General","rows":[{"fields":[{"attributeId":"code","size":"half"},{"attributeId":"name","size":"half"}]},{"fields":[{"attributeId":"parent_ref","size":"row"}],"dividerType":"normal","dividerTitle":"Hierarchy"}]},{"title":"Content","rows":[{"fields":[{"attributeId":"status","size":"quarter"},{"attributeId":"description","size":"threeQuarters"}]},{"fields":[{"attributeId":"image","size":"half"},{"attributeId":"tags","size":"half"}]}]}]} - `productLayout.sections` (array,null) Example: [{"title":"General","rows":[{"fields":[{"attributeId":"code","size":"half"},{"attributeId":"name","size":"half"}]},{"fields":[{"attributeId":"parent_ref","size":"row"}],"dividerType":"normal","dividerTitle":"Hierarchy"}]},{"title":"Content","rows":[{"fields":[{"attributeId":"status","size":"quarter"},{"attributeId":"description","size":"threeQuarters"}]},{"fields":[{"attributeId":"image","size":"half"},{"attributeId":"tags","size":"half"}]}]}] - `productLayout.sections.title` (string,null) - `productLayout.sections.rows` (array,null) - `productLayout.sections.rows.fields` (array,null) - `productLayout.sections.rows.fields.attributeId` (string,null) - `productLayout.sections.rows.fields.size` (string) Enum: "quarter", "half", "threeQuarters", "row" - `productLayout.sections.rows.dividerType` (string,null) Enum: "normal", "wide", "lineBreak" - `productLayout.sections.rows.dividerTitle` (string,null) - `variantLayout` (object) Example: {"sections":[{"title":"General","rows":[{"fields":[{"attributeId":"code","size":"half"},{"attributeId":"name","size":"half"}]},{"fields":[{"attributeId":"parent_ref","size":"row"}],"dividerType":"normal","dividerTitle":"Hierarchy"}]},{"title":"Content","rows":[{"fields":[{"attributeId":"status","size":"quarter"},{"attributeId":"description","size":"threeQuarters"}]},{"fields":[{"attributeId":"image","size":"half"},{"attributeId":"tags","size":"half"}]}]}]} ## Response 201 fields (application/json): - `@readLink` (string,null) - `@editLink` (string,null) - `@etag` (string,null) - `@navigationLinks` (array,null) - `@navigationLinks.uri` (string,null) - `@associationLinks` (array,null) - `@associationLinks.uri` (string,null) - `@context` (string,null) - `value` (any,null) ## Response 400 fields (application/json): - `validationFailures` (object,null) Example: {"Layout":[{"PropertyName":"Layout","ErrorMessage":"The layout must contain exactly the attributes of the stored layout.
