HubSpot is a leading CRM and marketing automation platform that helps businesses manage sales, customer service, and marketing campaigns from a centralized system. Thanks to its flexible and powerful REST API, HubSpot allows software providers to build seamless integrations to synchronize customer and invoicing data.
Offering a HubSpot API integration allows you to:
- Setup automated processes for your users
- Pull invoicing and customer data into your software for synchronisation or offer features such as accounting automation
- Enhance overall accuracy by reducing the risk of error associated with manual entries
This guide covers all the essentials for integrating with the HubSpot API, including best practices, API specifics, and use-case examples.
What is the HubSpot API?
The HubSpot API is a RESTful API that allows you to pull and push data across various CRM and sales objects. You can interact with data models such as contacts, companies, and more.
HubSpot is available as a connector through Chift’s Unified Invoicing & CRM API, which enables you to connect to HubSpot and other major European CRM and invoicing platforms with a single integration.

Getting you started with your HubSpot API integration
To connect to the HubSpot API, you will use OAuth 2.0. Here’s what you need to know:
- Carefully configure the OAuth scopes to ensure your application can access the necessary objects and perform both read and write operations.
- Common scopes include:
%%crm.objects.contacts.read%%,%%crm.objects.deals.write%%,%%crm.objects.invoices.read%%, etc.
You can find more setup details and the latest scope list in HubSpot’s official documentation.

Our recommendations for integrating with HubSpot
Here are some tips to help you experience a smoother integration setup with HubSpot's API
- Pay attention to OAuth scopes: Missing or misconfigured scopes can limit your ability to pull or push data. Always confirm you’ve enabled the appropriate ones.
- Use the Associations Bulk endpoint: HubSpot’s CRM objects are often linked to others. For example, when retrieving an invoice, you can use this endpoint to fetch all related line items and taxes in one go.
- Leverage filtering: HubSpot offers advanced filtering options that allow you to retrieve only relevant data, improving performance and reducing API usage.
