Why it matters
LinkedIn Finds More of What You Count as a Conversion
The LinkedIn Conversions API is LinkedIn's way to receive conversions from your own systems, not only from the browser. LinkedIn's bidding learns from what you send it: if all it hears about is form fills, it looks for more people who fill in forms.
- Send it the deals from your CRM, and it can look for more companies like the ones that bought.
- Closed-won deals go as Purchase, with the deal amount.
- Qualified opportunities go as Lead. Both go once a day.

Questions About the LinkedIn Conversions API
What is the LinkedIn Conversions API (CAPI)?
The LinkedIn Conversions API is LinkedIn's way to receive conversions server to server, from your own systems instead of the browser. DemandSense is connected to it and sends conversions from your CRM, so LinkedIn can optimize toward pipeline and revenue.
What does DemandSense send through the LinkedIn Conversions API?
Two events from your CRM, once a day. Closed-won deals go to LinkedIn as Purchase conversions with the deal amount, and qualified opportunities go as Lead conversions. You map each one to a conversion rule in Campaign Manager. Contact details are hashed before they're sent.
How is it different from the LinkedIn Insight Tag?
The Insight Tag sits on your website and reports what visitors do there, such as a form fill. The Conversions API takes conversions from your own systems; with DemandSense, the deals in your CRM. Keep the tag for site actions and use the Conversions API for deals.
Do I need a developer to set it up?
No. Connect your CRM in DemandSense, reconnect your LinkedIn ad account to grant one extra permission, and switch on the two streams. You need admin access to the LinkedIn ad account.
What are offline conversions on LinkedIn?
Results that happen away from your ads and your website, like a deal closed after a sales call. When the deal is in your CRM, DemandSense sends it to LinkedIn as a conversion, with no file to upload.
Will it change my running campaigns?
It adds conversion events to the conversion rules you choose. Campaigns that optimize toward those rules start learning from your closed deals. Nothing else in your campaigns changes.
What happens after the 30-day free trial?
You choose a paid plan to keep your Conversions API streams running. Plans start at $89 a month.
