Overview
The UserEvidence to HubSpot Connector is a fully serverless AWS integration that bridges your UserEvidence survey platform with HubSpot CRM, giving your sales and customer success teams instant visibility into customer sentiment directly inside HubSpot contact records.
HOW IT WORKS
The connector pulls survey recipient data from the UserEvidence REST API and maps it to 9 custom HubSpot contact properties: NPS score, survey link, survey response link, survey sent date, survey completed date, unsubscribe status, survey name, reference activities, and last response date. Contacts are matched exclusively by email address; no new contacts are ever created, ensuring your CRM data stays clean.
SYNC SCHEDULING
Flexible sync schedules let you choose from every 30 minutes, hourly, daily, or weekly cadences, with optional start and end date windows. Schedules are managed via Amazon EventBridge, which is automatically enabled or disabled based on active portal configurations. Incremental syncs use a cursor on the updated_at timestamp so only changed records are processed, keeping API usage and Lambda costs minimal.
SECURITY AND AUTHENTICATION
- HubSpot: OAuth 2.0 authorization code flow with automatic token refresh. Refresh tokens are encrypted with AES-256-GCM before storage in Amazon DynamoDB.
- UserEvidence: API key authentication (Bearer token), also AES-256-GCM encrypted at rest in DynamoDB.
- License validation: Per-HubSpot-portal license keys stored in AWS SSM Parameter Store; every Lambda invocation validates the license before processing.
- Network security: AWS WAFv2 IP allowlist restricted to HubSpot datacenter CIDRs; API Gateway throttling (50 req/s, 200 burst) to prevent abuse.
ARCHITECTURE
Built on AWS Serverless Application Model (SAM) with three Lambda functions:
- api Lambda - Handles OAuth flows, connection management, settings, and status endpoints surfaced in a React 18 HubSpot UI Extension embedded in App Settings.
- sync Lambda - Executes on-demand syncs triggered manually by the user.
- scheduler Lambda - EventBridge-triggered every 30 minutes; fans out to all portals that are due for a scheduled sync.
Failed syncs are routed to an SQS Dead Letter Queue with an SNS email alert when queue depth exceeds 3 messages. Sync history is stored in DynamoDB with a 90-day TTL. Estimated AWS infrastructure cost is approximately $9 to $11 per month at 50 customers.
