We imported companies records that were pre-existing in Hubspot having the same domain as the pre-existing one: Hubspot duplicated the records instead of merging the imported records with the existing ones having the same domain name.
Detailed description of what happened:
Company with name A and domain name A exists in Hubspot
Another Company B with domain B is created via API call (B has the same name and domain name as A)
Instead of merging Companies A and B, Hubspot created two separate companies
How to avoid duplication?
