Define the business event first
Start with what should happen for the user or team when two systems are connected. “Integrate CRM and app” is a direction; “create a qualified lead when this form is approved” is a workflow you can design and test.
List the source of truth and decide what happens when the systems disagree.
Plan for imperfect networks
Requests fail, providers throttle traffic and webhook events arrive twice or out of order. Use idempotency, retries with limits, timeouts, logging and a way to reconcile missed events.
A happy-path demo does not prove an integration is safe to operate.
Access, data and handover
Use least-privilege credentials, keep secrets out of client code and document provider accounts, data mappings and failure handling. Make ownership of API contracts explicit before launch.
Common questions
Can DevNexia help scope this work?
Yes. Share your goals, current product and constraints through the free assessment form and we can suggest a practical next step.
Are the costs and timelines guaranteed?
No. Custom software estimates depend on scope, integrations, team shape and feedback. A written estimate becomes more useful after requirements are understood.
