Creating company with domain containing german umlauts fails using API


Hello there,

I observed inconsistent behavior during company creation.
Imagine I have a domain that contains german umlauts (https://hofhä Using this domain in the hubspot UI to create the record works flawless.
Using the same domain for creating the company via API, the property ‘domain’ is considered invalid and the creation fails.

Can you hint me on a workaround or any solution?
Thank you and kind regards


Hi @maddy2101,

I can replicate that behavior on my end as well. I don’t believe this is working as expected; I’m going to touch base with product on this for some more information. I’ll reach back out to this topic when I have some more information.


Hi @maddy2101,

It's been a while, but I wanted to let you know that we've recently updated our API to properly handle umlauts in URLs. If you continue to see this issue going forward, please don't hesitate to reach back out in this thread.
