Duplicate contacts - Help please


#1

Hi we are using the api endpoint “http://api.hubapi.com/contacts/v1/contact/batch” to add contacts to hubspot. we are noticing that duplicate contacts are being created with the same email. Does anyone know why and how this is happening? i thought the unique identifier is email… Help please!

Hi @Jonny_Katz,

Would you mind sending some examples of those contacts where you are seeing duplicates created. It should not be possible to create contacts with the same email address so I would like to investigate further.

Feel free to DM me if you don’t want to post links to your contacts publicly.

done. PM. did you receive it?


#4

I did thank you very much, I’m looking into this now.


#5

Just verified this is a bug on our end (thank you for your examples they really helped) A fix should be out to prevent this going forward and the team will be running a merge job to fix the records that have already been created as duplicates. I’ll update here again once that’s done running.


#6

@Jonny_Katz, this merge job should now be complete, let us know if you see any issues related to this


#7

Please let me know which criteria you used to perform the merge. Thanks

The contacts were merged by their email address.
