Case study snapshot
- Client type: a business whose sales and support teams handle calls and text messages through RingCentral every day
- Service: custom RingCentral to HubSpot integration with AI call summaries
- Stack: Python, RingCentral API, HubSpot API
- Headline results: 1,000+ SMS and call records synced automatically, 20+ admin hours saved every week, 99% CRM data accuracy
The problem
The team made and received calls and texts in RingCentral all day, and logged them in HubSpot by hand through extension-level logging. Logging fell behind, so contact histories had gaps, recordings were hard to find and reports missed phone activity. That mattered most when a rep needed the history before a follow-up.
What we built
We replaced the manual process with a direct API integration written in Python that connects the RingCentral API to the HubSpot API:
- Call and SMS capture: a Python service monitors RingCentral for new calls, text messages and recordings across every extension.
- AI summary generation: each interaction is processed and paired with an AI-generated summary of the call or message.
- HubSpot timeline sync: the call or message, its recording and the summary are logged on the matching HubSpot contact timeline, with owner and deal links attached.
Problems we designed for
Integrations like this usually fail quietly, so we built in handling for the common causes: phone numbers stored in different formats (every number is normalized to one international format), duplicate contacts (merge rules with a clear winner), calls on extensions that were missed (sync at the account level), activity assigned to the wrong user (each extension mapped to the right HubSpot user), duplicate activities (the call ID is saved so anything already logged is skipped) and silent failures (alerts and automatic retries).
Measured results
- 1,000+ SMS and call records synced automatically, with no manual logging
- 20+ administrative hours saved every week
- 45% improvement in follow-up efficiency
- 99% CRM data accuracy through real-time synchronization of communication records
