Google and Facebook ads - Revenue Attribution

Developer Support APIs & Integrations
1

Hello community,

I have integrated our Facebook and Google ad accounts to our hubspot to have keep track of our media investments.

I want now to integrate our invoicing system (built in house) so I can feed revenue data to hubspot on a publisher/campaign level and ultimatly have a granular ROI dashboard.

I`ve been studying API docs, but could no have a clear understanding of wich parameters to use.

Can someone point me to the right documentation?

There are probably many ways to approach this. We may need more specific details on your desired outcome and process.

Adding @himanshurauthan to the conversation as well as he often has some pretty amazing insights!
