• Lookup Query
• Cache

The Lookup action retrieves a value from Shopify and inserts that value into an existing Arc message in the flow.

Lookup Query

Follow these steps to configure a Lookup query for the Shopify connector:

1. In the CData Arc flow, drag an arrow from the connector that will provide input to the connector.

2. Under Destination Type, select either XPath to insert the query response values into an XML file or Header to insert the query response value into a message header.

3. Provide the Destination for the query response values:
   • For XPath, enter the XPath value to the desired destination in the XML file, e.g. /Items/Invoices/Customer.
   • For Header, enter the name of the new message header for the data.
4. In the Lookup Query, enter the SQL query to retrieve data to retrieve from Shopify tables.
   • For XPath, format the path as ${XPATH:/path/to/element}. For example, SELECT CustomerID FROM Customers WHERE CustomerName = ${XPATH:/Items/Invoices/Customer}.
   • For Header, format the path as ${HEADER:HeaderName}.

5. If the query you entered could return multiple values, check Use first result to avoid errors.

6. Set Value Not Found Action to the desired behavior for values that cannot be found.

   

7. In the Arc flow, drag an arrow from the Shopify connector to the connector where you want your resulting XML or Header data to go.

Cache

The Shopify connector provides the ability to perform Lookup queries against a local cache instead of querying Shopify directly for each Lookup. This can improve query performance, especially with larger databases.

To enable this feature, check the Enable Cache box and configure the fields as needed. If a query returns no results from the cache, the connector then queries Shopify directly.

Note: If your query statement contains a limit, offset, or groupby parameter, the cache function will not work. These queries instead go directly to Shopify.
