Recently, we helped a client integrate HubSpot with Microsoft Dynamics. Like most integration projects, it sounded relatively straightforward at first: "We just need some basic data to sync between systems. Nothing too complicated."
With a native integration already created, how hard could it be?
As we dug in to their requirements and data structure, however, it became clear there was going to be a lot of planning and nuance involved in ensuring the integration was a success.
If you're thinking about integrating HubSpot with Microsoft Dynamics, here are a few important things to know based on our own experience.
Start by Defining Your Business Process
Before you even open HubSpot or Dynamics, get clear on your process.
What's the actual business reason for integrating? Are you trying to give your sales team better visibility? Make sure marketing can see what's happening in the pipeline? Improve reporting?
Be clear on why you're integrating so you can figure out what data needs to move and when.
We sat down with the client and mapped out their process end-to-end — what happens when a lead comes in, how it's qualified, who it's assigned to and how it moves through the sales cycle.
That step made the technical work way smoother because we weren't guessing what should trigger a sync or what fields mattered.
Choose Your Sync Points Wisely
Not all data needs to sync. In fact, syncing too much can create confusion and slow things down.
You'll need to decide which records and fields should move between systems, in which direction and under what conditions. Some things might only need to sync from Dynamics to HubSpot (or vice versa), while others need to go both ways.
One key thing we learned: figure out what triggers a sync in each system. In Dynamics, it might be a record status or assignment. In HubSpot, it could be tied to a lifecycle stage. Knowing these triggers ahead of time prevents surprises later.
Field Mapping Isn't Always Simple
Here's where things can get a little tricky. Even if two fields have the same name (e.g. "Phone Number" or "Lead Source") they might behave differently between platforms.
Some fields in HubSpot can't be edited through the API. That means if you try to sync data into them from Dynamics, it won't work. In our case, we ran into this with a few standard properties and had to create custom ones instead.
We also found differences in field types. For example, a text field in HubSpot might need to connect to a dropdown or lookup field in Dynamics. If they don't match, you'll have to either adjust one side or build logic to translate between the two.
Don't Overlook Custom Objects and Lookups
If you're using custom objects in HubSpot, you'll want to double-check how those line up with any lookup fields in Dynamics.
We ran into a snag where a workflow broke because the lookup in Dynamics was pointing to a record type that didn't match the HubSpot custom object. Once we mapped those more deliberately and added the right support fields, things started clicking.
This part definitely takes some thought. Just because you can technically link something doesn't mean it's going to work without some extra configuration.
Lifecycle Stages Matter More Than You Think
In HubSpot, Lifecycle Stage is one of those properties that powers a ton of automation and reporting. Even if you don't think you need it now, it's worth making sure your integration supports it properly.
We built logic to keep Lifecycle Stage aligned with where a contact or company stood in Dynamics. That helped the marketing team keep their lists clean and gave them better insight into lead progress without needing to check Dynamics all the time.
Syncing Users Requires Extra Attention
One small but important detail: in Dynamics, users are usually referenced by name or ID. In HubSpot, record ownership is typically tied to an email address.
This can cause issues when trying to sync record owners between systems. To get around that, we created custom text fields in HubSpot to store the corresponding Dynamics user emails. That let us set up reliable ownership workflows and made it easier for both systems to "speak the same language" about who owns what.
Document Everything and Test (Everything)
Once your fields are mapped and your workflows are built, document everything. That includes:
- Which fields sync and how
- Any workarounds or custom logic
- What triggers the sync
- Known limitations
Even if you think you'll remember, you won't — and someone else on your team definitely won't. Good documentation makes ongoing maintenance and troubleshooting much easier.
Also: test everything. Syncs. Field updates. Ownership changes. Record creation. Do it all in a sandbox environment if you can before rolling it into production.
Final Thoughts
Integrating HubSpot with Microsoft Dynamics can be incredibly valuable, but it's not a plug-and-play job. It takes planning, testing and often a few creative solutions.
If you're planning this kind of integration, or if you're in the middle of one and could use a second set of eyes, we'd be happy to help. We've been through it, and we know what to watch out for.
