Handle API authentication, pagination, rate limits, retries, and error handling.
Monitor integration performance and resolve synchronization failures.

4. Retail Data Mapping & AI Platform Integration

Map POS data fields to Daisy Retail's standardized data model.
Ensure accurate ingestion of sales, pricing, promotions, product, and inventory information.
Work with Daisy's AI and analytics teams to understand data requirements for price optimization and promotional recommendations.
Validate historical and ongoing data feeds to support AI analysis.
Maintain data consistency across multiple stores, POS systems, and retail customers.
Support onboarding of new retail data sources as Daisy expands its AI capabilities.

5. Customer Onboarding & Technical Implementation

Manage technical implementation after POS partnerships are established.
Conduct technical discovery sessions with POS partners and retail customers.
Gather integration requirements and assess technical feasibility.
Configure and test data integrations for new retail customers.
Coordinate user acceptance testing, production deployment, and go-live activities.
Provide technical troubleshooting and post-implementation support.
Collaborate with internal engineering, product, customer success, and business development teams.

6. Data Security, Monitoring & Documentation

Implement secure data transfer, encryption, and credential management.
Follow least-privilege access principles for POS databases and APIs.
Maintain integration logs, monitoring, alerts, and audit trails.
Document API specifications, database mappings, integration workflows, and troubleshooting procedures.
Ensure reliable and scalable integration architecture.
