Smartsheet API Integration and Automation

We are seeking a skilled freelancer to create an API integration in Smartsheet. The system must function flawlessly, as payment will only be made if the solution works properly. The work cannot be left incomplete, requiring us to hire someone else again. Once this task is successfully completed, further tasks may be assigned. Additionally, access to another similar sheet will be provided, and with your guidance, we will independently integrate it into the existing tables. Please confirm your ability to deliver under these terms.
