### findAll
\
RequestContext, options?: ListQueryOptions<Product>, relations?: RelationPaths<Product>) => Promise<PaginatedListProduct>>>`} />
### findOne
\RequestContext, productId: ID, relations?: RelationPaths<Product>) => PromiseProduct> | undefined>`} />
### findByIds
\RequestContext, productIds: ID[], relations?: RelationPaths<Product>) => PromiseProduct>>>`} />
### getProductChannels
\RequestContext, productId: ID) => Promise<Channel[]>`} />
Returns all Channels to which the Product is assigned.
### getFacetValuesForProduct

### findOneBySlug
\RequestContext, slug: string, relations?: RelationPaths<Product>) => PromiseProduct> | undefined>`} />
### create

### update
\RequestContext, input: UpdateProductInput) => PromiseProduct>>`} />
### softDelete
\RequestContext, productId: ID) => Promise`} />
### assignProductsToChannel
\RequestContext, input: AssignProductsToChannelInput) => PromiseProduct>>>`} />
Assigns a Product to the specified Channel, and optionally uses a `priceFactor` to set the ProductVariantPrices
on the new Channel.
Internally, this method will also call [ProductVariantService](/current/core/reference/typescript-api/services/product-variant-service#productvariantservice) `assignProductVariantsToChannel()` for
each of the Product's variants, and will assign the Product's Assets to the Channel too.
### removeProductsFromChannel
\RequestContext, input: RemoveProductsFromChannelInput) => PromiseProduct>>>`} />
### addOptionGroupToProduct
\RequestContext, productId: ID, optionGroupId: ID) => PromiseProduct>>`} />
### removeOptionGroupFromProduct
\RequestContext, productId: ID, optionGroupId: ID, force?: boolean) => Promise<ErrorResultUnionProduct>>>`} />
