Writing the response from a RESTful API to a SQL database
Take the response from an API and write it to a database. Simple but very, very useful.
In this demo, we'll sync billing data from the Demo Billing API to a SQL database.

Line by Line: How this "Restful API to SQL" demo works
The demo-api-billing and demo-rest-to-sql packages each have their own setup service to configure the database connection to be used in the demo:
The setup service for creating the database connection pool for demo-api-billing.
The setup service for creating the database connection pool for demo-rest-to-sql.
Syncing the Invoice data from demo-api-billing to the database.
In the reporting dashboard, the SYNC DATA button is configured to call a service exposed as an adhoc REST API called RefreshService.The code\demo_rest_to_sql\services\RefreshService uses several Functions to pull the data from the demo-api-billing:
- Line 3: demo_rest_to_sql.services_imported.billing_api.invoices.DemoApiBillingServiceInvoicesSelectAllInvoices \ This is a service that was generated by consuming the demo-api-billing OpenAPI schema. This service calls to an API endpoint from demo-api-billing to get all the invoice data
- Line 4: demo_rest_to_sql.services_imported.billing_api.invoiceLines.DemoApiBillingServiceInvoicelinesSelectAllInvoiceLines \ This is a service that was also generated by demo-api-billing OpenAPI schema. This service calls an API endpoint from demo-api-billing to get all the invoice line items.
- Line 5: demo_rest_to_sql.services_imported.billing_api.payments.DemoApiBillingServicePaymentsSelectAllPayments \ Also a service generated from demo-api-billing’s OpenAPI schema, this service calls to an API endpoint that retrieves all the payment data from demo-api-billing
- The rest of the steps are iterating through these data from demo-api-billing and saving them to the database.
When the SYNC DATA button is clicked, it will trigger the service mentioned in the previous step to pull all invoice data from the Billing API, and saves it to the database.
