From our clients

See how our customers—from some of the world's largest companies to the most innovative startups— work with us to reach their business goals.

The Webstacks team did a great job connecting our Magento based site into HubSpot and then into NetSuite (our ERP). It was a complex integration and their team was responsive and ensured that we were satisfied with the integration at the end of the day.
Consider yourself lucky if you can add them to your roster of talent to drive business results.
Webstack's team is fantastic. Let's be real, most agencies let you down, sooner or later. I feel like we really leveled up our website when we partnered with the Webstacks team. We're excited to continue the relationship.

Frequently Asked Questions

We're not your typical agency — so we get a lot of questions. Read our answers below.

What is an API?

API stands for Application Programming Interface. Software programs use APIs to connect one or multiple platforms in order to share data or leverage unique features. With HubSpot, companies can scale faster by integrating their favorite tools.

What is a webhook?

A webhook is like an API, in that it connects two applications to share information. However, a webhook delivers data in real-time whereas APIs provide data upon request.

Why should I integrate with HubSpot?

As a relationship between two people, growth happens when there is open communication and trust. By integrating your existing sales, marketing, and support tools with HubSpot, we can create value that is worth more than the sum of its parts.

Can you build custom API integrations?

Yes. In most cases, we are able to integrate the software with API capabilities with HubSpot. For cost and timeline clarifications, contact our sales engineers.

What common integrations do you build?

Some common integrations we help our clients configure include Salesforce, Mailchimp, Slack, Linkedin, Facebook, Instagram, Twitter, Zoom, Outlook, PandaDocs, and Shopify.

How do you work with your clients?

Like APIs, we build meaningful connections with our partners and we believe that success is the result of collaboration and communication. For that reason, we give our partners direct access to our HubSpot consultants in a shared Slack channel, meet weekly to discuss sprints, and review open tasks in Asana.

How long do HubSpot integrations take?

Like many development tasks, the answer varies. Pre-built application integrations through HubSpot’s marketplace take very little time, whereas custom integrations will take significantly longer. For an API integration estimate, reach out to our sales team!

How much do HubSpot API integrations cost?

Because every client is different, it’s difficult to estimate a single cost. If you’re interested in working with Webstacks to build API integrations on HubSpot, talk to our sales team!
