23R2 - How to Create a New Entity for Shopify Connector to Sync Data to Shopify

@vivekm , create a new entity and handle the sync process are very complicated, based on your requirement, the following are the key points to create a new entity processor:

1. Create a new entity bucket object

   public class SPCustomItemEntityBucket : SPProductEntityBucket<MappedStockItem>
   {
   }

    

2. Create a new Processor that inherits from BCProcessorSingleBase, and attached the BCProcessorAttribute to the new Processor

   aBCProcessor(typeof(SPConnector), "CI", "Custom Item", 39,
   	IsInternal = false,
   	Direction = SyncDirection.Export,
   	PrimaryDirection = SyncDirection.Export,
   	PrimarySystem = PrimarySystem.Local,
   	PrimaryGraph = typeof(PX.Objects.IN.InventoryItemMaint),
   	ExternTypes = new Type ] { typeof(ProductData) },
   	LocalTypes = new Type ] { typeof(StockItem) },
   	AcumaticaPrimaryType = typeof(PX.Objects.IN.InventoryItem),
   	AcumaticaPrimarySelect = typeof(Search<
   		PX.Objects.IN.InventoryItem.inventoryCD,
   		Where<PX.Objects.IN.InventoryItem.stkItem, Equal<True>>>),
   	URL = "products/{0}",
   	Requires = new stringt] { }
   )]
   public class SPCustomItemProcessor : BCProcessorSingleBase<SPCustomItemProcessor, SPCustomItemEntityBucket, MappedStockItem>
   {
   }

    

3. Create data provider and Initialize the processor

   hInjectDependency]
   protected ISPRestDataProviderFactory<IProductRestDataProvider<ProductData>> productDataProviderFactory { get; set; }
   
   protected ISPRestDataProviderFactory<IChildRestDataProvider<ProductVariantData>> productVariantDataProviderFactory { get; set; }
   protected IProductRestDataProvider<ProductData> productDataProvider;
   protected IChildRestDataProvider<ProductVariantData> productVariantDataProvider;
   #region Constructor
   public override async Task Initialise(IConnector iconnector, ConnectorOperation operation, CancellationToken cancellationToken = default)
   {
   	await base.Initialise(iconnector, operation, cancellationToken);
   	var client = SPConnector.GetRestClient(GetBindingExt<BCBindingShopify>());
   
   	productDataProvider = productDataProviderFactory.CreateInstance(client);
   	productVariantDataProvider = productVariantDataProviderFactory.CreateInstance(client);
   }
   #endregion

    

4. Override the key methods to fetch data/mapping data/save data 

   public override Task FetchBucketsForImport(DateTime? minDateTime, DateTime? maxDateTime, PXFilterRowi] filters, CancellationToken cancellationToken = default)
   {
   	throw new NotImplementedException();
   }
   
   public override Task<EntityStatus> GetBucketForImport(SPCustomItemEntityBucket bucket, BCSyncStatus status, CancellationToken cancellationToken = default)
   {
   	throw new NotImplementedException();
   }
   
   public override Task SaveBucketImport(SPCustomItemEntityBucket bucket, IMappedEntity existing, string operation, CancellationToken cancellationToken = default)
   {
   	throw new NotImplementedException();
   }
   
   public override async Task FetchBucketsForExport(DateTime? minDateTime, DateTime? maxDateTime, PXFilterRowi] filters, CancellationToken cancellationToken = default)
   {
   	//It is used for screen BC501000(Prepare Data):
   	//1. Fetch the data from ERP by BQL query or CBAPI
   	//2. Created the MappedStockItem instance and call EnsureStatus method to create the sync record.
   	//MappedStockItem mapped = new MappedStockItem(entity, entity.SyncID, entity.SyncTime); //entity is a StockItem object.
   	//EntityStatus status = EnsureStatus(mapped, SyncDirection.Export);
   }
   
   public override async Task<EntityStatus> GetBucketForExport(SPCustomItemEntityBucket bucket, BCSyncStatus status, CancellationToken cancellationToken = default)
   {
   	//This is the method for fetching ERP data during the export data process.
   	//1.Get the item details from ERP
   	//2.Assign the local item to the bucket, the bucket.Product.Local is a StockItem; bucket.Product.Exten is a ProductData(a data model that represents the Shopify product)
   	//3.Call EnsureStatus to refresh the sync status.
   	//MappedStockItem obj = bucket.Product = bucket.Product.Set(entity, entity.SyncID, entity.SyncTime);
   	//EntityStatus status = EnsureStatus(obj, SyncDirection.Export);
   }
   
   public override async Task MapBucketExport(SPCustomItemEntityBucket bucket, IMappedEntity existing, CancellationToken cancellationToken = default)
   {
   	//for the default mapping between ERP data and external data object.
   	//bucket.Product.Local is a StockItem
   	//bucket.Product.Exten is a ProductData(a data model that represents the Shopify product)
   }
   
   public override async Task SaveBucketExport(SPCustomItemEntityBucket bucket, IMappedEntity existing, string operation, CancellationToken cancellationToken = default)
   {
   	//for saving data to External platform during the export process.
   	//Use the productDataProvider to create/update ProductData to Shopify
   	//Use the productVariantDataProvider to create/update Product variant data to Shopify
   	//Update the sync record.
   	MappedStockItem obj = bucket.Product;
   	ProductData data = null;
   	data = await productDataProvider.Create(obj.Extern);
   	obj.AddExtern(data, data.Id?.ToString(), data.Title, data.DateModifiedAt.ToDate(false));
   	UpdateStatus(obj, operation);
   }
