How to Integrate with the HubSpot API: A Step-by-Step Guide for B2B SaaS Teams

Integrating with the HubSpot API offers powerful CRM functionalities for B2B SaaS teams, enabling access to contacts, companies, deals, and more, but brings operational complexities, particularly when scaling to support multiple customer accounts. The process involves setting up a HubSpot developer account, creating an OAuth 2.0 app, configuring scopes, handling OAuth credentials, implementing the OAuth flow, and managing webhooks. Alternatively, using Unified's CRM API can simplify integration by providing a unified API surface that handles OAuth exchanges, retry logic, and schema mapping, particularly beneficial for teams managing multiple CRMs or seeking to avoid building and maintaining direct vendor logic. Choosing between direct integration and using Unified depends on the scope and scale of CRM support needed, with direct integration offering full control for HubSpot-specific features and Unified offering streamlined operations across multiple CRMs with usage-based pricing.
