How to prevent duplicated contact in Insightly integration

it seems that each time we have a person fill out  new form, as we have several forms we need filled out by each client, it creates a new contact in insightly for them so we are getting duplicate and triplicate contacts.

You will need to configure the Duplicate Checks detection in your Insightly account settings.

Check the guide in Insightly here: https://support.insight.ly/hc/en-us/articles/204248460-Duplicate-checks-when-importing

Let us know if this did not resolve the issue for you.

Thanks.
