Conversion tracking which involves a HubSpot and double opt-in process with Google Ads

Hello everyone,

I am trying to configure a conversion tracking, the process includes a HubSpot form submission and e-mail reception with double opt-in link and click (the double opt-in link url is not hosted in the website domain so the GTM conversion tracking is not an option).
As far as I understood, Goog Ads API might be an option but I couldn’t find the guideline for my case yet. Could someone help? It can be any alternative way if you do have an idea.
Thanks in advance

Great ask,

Definetly it is doable with google Ads API

Try the reference material - https://console.cloud.google.com/marketplace/product/google/googleads.googleapis.com?pli=1

Also you can try with other options which are listed below:

HubSpot Ads Add-On
Zapier
Custom Webhooks
HubSpot Custom Integrations
Utilize URL parameters and UTM tracking to track the source of conversions

Kindly mark this as solved use case if incase it is all aligned - which will also help other pursuers

Hope this helps - Happy to help further !!

Thank you very much and have a fantastic day!

Warm regards
