HubSpot API Integration

I connect HubSpot to your ERP, your own app or your order system. Data flows in an agreed direction, nobody retypes it, and if the connection stops working, the person you choose gets an alert.

What companies come to me with

The same customer entered twice

A new customer shows up in the ERP, someone creates them again in HubSpot, and months later nobody knows which address is current.

A marketplace app covers half the process

The app syncs contacts but skips orders or the fields sales depends on. Someone fills in the rest by hand.

A script that quietly broke

An old script died after an API change, and the company finds out from a rep who hasn’t seen new customers in the CRM in a long time.

What I usually connect through the API scope set in the process review

Contacts and companies

A customer is created once

A new customer in the ERP creates a contact or company in HubSpot, and selected properties flow back to the other system.

Orders

Won deal to ERP order

A won deal creates an order in the ERP with the deal’s line items, and fulfillment status flows back to HubSpot.

Events

A HubSpot change triggers an action

A deal stage change sends data to another system through a workflow webhook or a HubSpot private app.

Product

Data from your app

User activity as properties or events, and product signals in lead scoring. Data outside the HubSpot model goes to a custom object.

Common connections

Stores, invoicing and payments

I most often connect HubSpot to online stores, invoicing and accounting tools, Magento and Stripe.

HubSpot integrations

How we work together

  1. 1

    Free consultation30 minutes

    You tell me which systems need to connect to HubSpot and what someone retypes between them today. I tell you what can be done.

  2. 2

    Process reviewScope set after the consultation

    We map out systems, data and flow directions. For each field we set the source of truth and the key used to match records.

  3. 3

    BuildExisting integration or custom

    I check the official integration first and write custom code for whatever it doesn’t cover, kept safely under HubSpot’s API limits, with retries.

  4. 4

    Testing and launchOn real data

    I test on your data and we set a start date. Every operation is logged, and if the integration stops working, the person you choose gets an alert.

  5. 5

    Ongoing supportOn demand or on a retainer

    After launch you reach out when you need something, or we agree on a fixed scope of work for each month.

Questions before an integration

Can HubSpot connect to our system?

If your system has an API or can send a webhook, it can be connected to HubSpot.

Which system is the source of truth?

We decide that field by field, along with the key for matching records: a person by email address, a company by tax ID or ERP ID.

Make or custom code?

Make when the scenario is simple and your team will maintain it. Custom code in Node or Python on AWS when the logic is complex.

What if the integration stops working?

The person you choose gets an alert. Every operation is logged, so you can see when data stopped flowing, and once it’s fixed the missing data can be backfilled.

Who maintains the custom code?

Custom code needs maintenance, which is why I only write it where an existing integration falls short. Support after launch is agreed separately: an hours package, a fixed monthly scope or both.

How much does it cost?

It depends on the number of systems and steps. You get a quote after the process review.
