 | getProducts | `string[]` Product IDs/skus | `Promise<Product[]>` | Get a list of products (consumable and non-consumable items, but not subscriptions). Note: On iOS versions earlier than 11.2 this method _will_ also return subscriptions if they are included in your list of SKUs. This is because we cannot differentiate between IAP products and subscriptions prior to 11.2. |

 | getPurchaseHistory | | `Promise<Purchase[]>` | Gets an invetory of purchases made by the user regardless of consumption status (where possible) |
