Modifiers are stored on the product and returned automatically in all endpoints that return products.

​
Behavior

The endpoint returns 202 Accepted immediately. Products are processed in the background.
If the branch code does not match any branch in the store, the product is created without a branch assignment. No error is produced.
If a category does not exist, it is created automatically within the store and the corresponding branch.
Images are downloaded and processed in the background after the product is created.
Variations are identified by their SKU. If a variation with that SKU already exists, it is updated instead of creating a new one.
If modifier_groups is absent in the payload, existing modifiers are preserved. If it is an empty array [], all modifiers are deleted. If it has data, modifiers are completely replaced.

​
Validation errors

If the data does not meet the validation rules, the API responds with 422 and details the fields with errors.

  "message": "The resources field is required.",
  "errors": {
    "resources": ["The resources field is required."]
