Our API between our ERP and CRM created duplicates for almost each of our deals saved in Hubspot

Hello !

We have had an active API between our ERP and our CRM, HubSpot, since 2020.

Last Friday, the API created a duplicate for almost every study created since 2020 in our CRM. We went from 9,000 deals to 17,000 deals in our HubSpot between 1:00 AM and 11:40 AM the same day.

To date, we've never experienced this type of issue.

At the beginning of March 2025, we migrated to version 3 of HubSpot’s Owners API as recommended by HubSpot.

Hubspot's support replied this is not linked and they do not have any explanation to what happened.

It seems deals were created again with exactly the same information when the API did not find the contact associated to this deal. Even if the initial deal is associated to a contact. We cannot exactly figure out what is the problem.

What do you think about it ?

Have you already experienced this kind of issue/ situation with an API between an ERP and a CRM?

Looking forward to hearing from you,

Many thanks,

Elo

Are you able to access the payload to the requests being made to Hubspot?

Given what you said that it's creating the exact same deals, that Deal API is probably fine. So it's likely prior to that when it checks for the deal associated with the contact and returns false (no associated deals).

Did you compare the response from V2 and V3 for the Owners API? The data returned is not in the same format.

Eg,

ownerId in V2 looks to be id in V3

What are you checking for? Can you manually run the request (in something like Postman) and see what is returned? What are the steps of the entire process?

Hello Michael,

Thank you for your reply and your questions.

I do not have any answer as I am from the busdev team. Our API partner is out of the office for 3 weeks.

I will keep you informed as soon as he will have reviewed your comments.

Have a great week,
