Is There a Quickbooks API For Automation ?

Hello,

We have an existing ERP database that we rely on for project management.

Our old payroll and some accounting functions interact with that project management system for the purposes of planning and reporting.

We need to automate the process of creating payroll projects and the aggregation of payroll expenditures into our ERP database system.

Is there a cURL API that we can use to move that automation to Quickbooks Online?

Thanks
