Shopify API Integration Needed

I'm in search of an experienced API integration specialist to create a robust integration between 3rd party platforms and a Shopify store. This project aims to automate the flow of sales data, including payment details, from 3rd parties (creating sales channels) directly into Shopify, enabling us to synchronise orders and maintain up-to-date order information seamlessly.

Error Handling and Logging for comprehensive mechanisms to catch and address any issues during data transfer. Security Measures to manage authentication processes, safeguarding API keys and sensitive data against unauthorised access. Testing and Deployment thorough testing, including edge case scenarios, to ensure the integration's reliability and effectiveness. Prepare and execute a deployment plan, including setting up monitoring tools for ongoing performance tracking.
