Overview

HubSpot connects sales, marketing, and service data through REST APIs and webhooks - ConnectSoft integrates it when GTM teams already live in HubSpot and your product must stay the system of record for transactions.

We implement OAuth apps, incremental sync, and conflict rules in ASP.NET Core workers - pairing HubSpot with Microsoft Entra ID-authenticated internal tools and Azure Service Bus for reliable event delivery.

Custom objects, deal pipelines, and marketing events are mapped explicitly so CRM hygiene does not erode over time - with observability and replay tools for operators.

If HubSpot is part of your GTM stack, we integrate it with the same engineering discipline as your core Azure microservices.

Why we integrate it:

  • OAuth 2.0 private app or public app flows
  • Incremental CRM sync with deduplication rules
  • Webhook subscriptions with signature validation
  • Rate-limit aware HttpClient with Polly policies
  • Mapping documented between HubSpot objects and your domain
  • Staging sandboxes for schema and workflow changes
