LinkedIn Conversions
Add LinkedIn Conversions to your product for your customers, and give your AI agents governed access to it.
The LinkedIn Conversions API exists because the interesting conversion usually happens somewhere LinkedIn cannot see: a trial that turns into a contract weeks later, a phone enquiry, a signature. Your server sends the event instead. The shape is small and strict. A conversion rule is created once on the advertiser's ad account and every event refers to it, identifiers are hashed before they leave your product rather than sent in the clear, and each event carries its own timestamp and, where you have one, a value and currency, so a deal that closed on Tuesday is attributed to Tuesday and not to the day you got around to sending it. Matching is probabilistic, which means the more identifiers you can attach the better the attribution gets, and an event with none of them is simply discarded. fastn holds each advertiser's authorisation per tenant and tracks LinkedIn's versioned API.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each advertiser connect their own ad account, then create the conversion rules your product will report against.
Send a conversion event from your backend when a deal is won, a subscription starts or an invoice is paid.
Hash email addresses and other identifiers inside your product so raw personal data never leaves it.
Report offline conversions such as a phone order or a signed contract, with the timestamp of the event rather than of the upload.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent checks which conversion rules an ad account has and which of them your product is actually feeding.
An agent reports the conversion events sent for an account this month and the total value attached to them.
An agent flags a rule that has stopped receiving events, within scoped permissions and with the check logged.
Example prompt
How many closed-won conversions did we report to LinkedIn for this ad account last month, and what value did we attach?
Set up LinkedIn Conversions in 4 steps
- 01Enable the LinkedIn Conversions connector in your fastn dashboard.
- 02Have each advertiser authorise their own ad account so rules and events belong to them.
- 03Create the conversion rules your product reports against, and decide which identifiers you will hash and send.
- 04Call it from your product and expose the same governed connection to your agents.
Why teams use the LinkedIn Conversions integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a LinkedIn Conversions integration without building it. Your customers connect their own LinkedIn Conversions account inside your product and work their campaigns, segments and subscribers there, with no per-customer code on your side.
- Handle the part that actually costs time: engagement data arrives as a high-volume event stream, so ordering and deduplication matter. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a LinkedIn Conversions update is not your on-call problem.
- One integration serves your product and your agents. The same governed LinkedIn Conversions connection powers in-product features and gives AI agents scoped, audited access, so you trigger and measure campaigns from inside your product without wiring it twice.

Zoho CRMLinkedIn Conversions integration FAQ
How do I add a LinkedIn Conversions integration to my product?
Enable the LinkedIn Conversions connector in your fastn dashboard, then let each customer authenticate their own LinkedIn Conversions account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no LinkedIn Conversions client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own LinkedIn Conversions account?
Yes. Every connection is scoped to the individual customer, so each authorises their own LinkedIn Conversions account and only ever sees their own campaigns, segments and subscribers. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this LinkedIn Conversions integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent checks which conversion rules an ad account has and which of them your product is actually feeding.
Who maintains the LinkedIn Conversions integration?
fastn does. When LinkedIn Conversions changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can I trigger a LinkedIn Conversions campaign from an event in my product?
Yes. Product events can start a campaign, add a contact to a segment, or enrol someone in a journey, so lifecycle messaging follows what a user actually did rather than a nightly export.
Can I read engagement results back from LinkedIn Conversions?
Yes. Results come back scoped per tenant, so your product can act on them without one customer's data mixing with another's. What you get depends on the channel: opens, clicks, bounces and unsubscribes where there are sends, and impressions, spend and conversions where there are campaigns.
What can I build with the LinkedIn Conversions integration?
A common starting point: let each advertiser connect their own ad account, then create the conversion rules your product will report against. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the LinkedIn Conversions integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding LinkedIn Conversions does not change your per-connector cost. You can start free with 3 connected accounts.
