How we've helped others connect their tech stacks

"HarvestROI worked with developers in getting our customer API created... HarvestROI definitely wants us to succeed, and if you are looking for a genuine partner to help you with anything HubSpot, Sales, Marketing, etc - you couldn't ask for a better one! "

“The decision to utilize HarvestROI alongside our HubSpot CRM was a no brainer from the beginning. Their team has helped us not only create seamless API integrations between our legacy product and HubSpot, they have even helped better streamline our sales workflows through various features built into the CRM. HarvestROI has now become a permanent extension to our sales & market development departments.”

“We reached out to HarvestROI with what most would be considered an unrealistic task. Their team quickly jumped in, helped us organize our goals and setup a powerful and effective workflow in HubSpot that created an efficiency within our company that never existed before.”

Have Questions?

Custom API & Integration FAQs?

Do you only build HubSpot integrations and APIs?

For the majority of our clients, the HubSpot CRM serves as their central source of truth. Accordingly, we generally develop and build APIs that connect to HubSpot or link platforms that are part of a tech stack including HubSpot. There are of course exceptions to this rule based on specific need within our broad capability. Please reach out to our team to discuss your project - we're happy to scope it out. 

What pre-made HubSpot integrations are available?

There is a vast library of native HubSpot integrations that have been approved and verified by HubSpot developers and staff. 

HubSpot maintains a marketplace of all its connected applications.

A native integration will be easy to set up and give you immediate access to the functionality you need.

Here are some typical examples of standard integrations:

- The Google Adwords integration tracks customer acquisition from the Google Ad right the way through the HubSpot customer journey.

- The AirCall integration allows you to make and log calls directly out of your HubSpot portal.

- The PandaDoc integration allows you to use templated documents that can be automatically sent from HubSpot throughout the buyer's journey.

What if the integration I want isn't within the HubSpot marketplace?

We can build it! If you can’t find a native integration in the HubSpot Marketplace that meets all of your needs, reach out to our team to build a custom-coded integration/API that will meet ALL of your data synchronization needs.

How long does a custom integration or API take to build?

Depending on the complexity of your project, custom integrations/APIs can take anywhere from 2 weeks to 90 days.

How much does a custom integration or API cost?

Because every business process and API can be different, it’s hard to provide an accurate estimate without scoping the complexity of the project.

Please reach out to our team to describe the project - we'll scope it out and provide an accurate estimate for you!

What is the cost of NOT using integrations or APIs with my tech stack?

Lost revenue, wasted time, inaccurate data, poor visibility, human error...

Simply stated, businesses that effectively utilize technology to power their processes and inform their strategies scale more quickly and sustainably than business that don't. 

We help our clients to tactically employ streamlined tech stacks that provide cost efficient solutions for supporting teams an powering intelligent revenue generating machines.
