Pipedrive product variations resource — nested under a product id.

Variations are a separate v2 API from ExPipedrive.Products: /api/v2/products/:id/variations. Because every call is scoped to a product_id (unlike the single flat top-level path assumed by ExPipedrive.Resource), this module builds its own Request calls rather than implementing the Resource behaviour.

Pipedrive does not expose a "get one variation" endpoint — only list/create/update/delete. get/3 is a client-side convenience that scans stream/3 pages for a matching id.

Example

{:ok, variation} =
  ExPipedrive.ProductVariations.create(client, product_id, %{
    name: "Large",
    prices: [%{currency: "USD", price: 24.99}]
  })

{:ok, page} = ExPipedrive.ProductVariations.list_page(client, product_id)
variations = ExPipedrive.ProductVariations.stream(client, product_id) |> Enum.to_list()

{:ok, updated} =
  ExPipedrive.ProductVariations.update(client, product_id, variation.id, %{name: "XL"})

{:ok, _} = ExPipedrive.ProductVariations.delete(client, product_id, variation.id)
