Connect two tools without a native integration Prompt

Help me connect two tools that don't have a native integration.

Tool A: [name and what it does]
Tool B: [name and what it does]
What I want to happen: [data flow — when X in Tool A, do Y in Tool B]
Data to transfer: [specific fields]
Available options: [API / webhooks / Zapier / export-import]
Technical level: [non-technical / comfortable with APIs / developer available]

Please recommend:
1. Best approach given our technical level
2. Step-by-step implementation
3. Limitations vs a native integration
4. What to monitor for data accuracy
