How to set only variant or options for product variant through API

[rolinbos]

Is it possible to update only the options or the variants of a product variant through the PHP API?

Hey 👋

You can update both the options & variables like this, using the productVariants method:

$product->productVariants([
  'variants' => [
    ['name' => 'Colour', 'values' => ['Red', 'Green', 'Blue']],
    ['name' => 'Size', 'values' => ['Small', 'Medium']]
  ],
  'options' => [
    [
      'key' => 'Red_Small',
      'variant' => 'Red, Small',
      'price' => 1599,
    ],
    [
      'key' => 'Red_Medium',
      'variant' => 'Red, Medium',
      'price' => 2950,
    ],
    // Green_Small
    // Green_Medium
    // Blue_Small
    // Blue_Medium
  ],
]);

If you want to update only the variants or options while keeping the existing values, you still need to include both in your update. This is because the productVariants method replaces the current value of the product_variants field.

For instance, if you want to update the options but leave the variants unchanged, you can do something like this:

$product->productVariants([
  'variants' => $product->productVariants()['options'],
  'options' => [
    [
      'key' => 'Red_Small',
      'variant' => 'Red, Small',
      'price' => 1599,
    ],
    [
      'key' => 'Red_Medium',
      'variant' => 'Red, Medium',
      'price' => 2950,
    ],
    // Green_Small
    // Green_Medium
    // Blue_Small
    // Blue_Medium
  ],
]);
