Fifteen tabs. A spreadsheet. Manually copying orders from the shop into the CRM. “Someone will write a script later.” Sound familiar?
API integration sounds technical; business-wise it’s simple: systems should talk to each other — not through a human and Ctrl+C.
Why a “cheap script” gets expensive
A one-off script with no logs, no retries, no error mapping and no docs works… until one API field changes. Then you’re calling a developer on the weekend.
A solid integration has:
- a clear contract (what flows where)
- idempotency (the same event twice doesn’t create chaos)
- monitoring and alerts
- a queue / retry on outages
- permissions and an audit trail
Connections that usually pay off
- Shop ↔ accounting / invoicing
- Shop ↔ warehouse and shipping (Zásilkovna and similar)
- Website ↔ CRM (leads, deal status)
- Website forms ↔ Slack / email / CRM
- Payment gateway ↔ order and payment status
How we approach it at PrometeyLabs
1. Flow map — what’s the source of truth, what’s derived. 2. MVP integration — one critical path end-to-end. 3. Observability — you see it when it breaks. 4. Expand — more entities only after the first path is stable.
Cost and time (ballpark)
Simple form webhook → CRM: days, not months. Two-way catalogue and stock sync: weeks. “Connect everything to everything” with no priorities: a trap.
Conclusion
APIs aren’t a luxury for enterprises. They’re how you stop paying people to be the cable between systems.
