Google Ads
Add Google Ads to your product for your customers, and give your AI agents governed access to it.
Google Ads holds the spend, and a Google Ads integration lets your product read and change it without a person in the console. The objects are accounts, campaigns, ad groups, keywords, budgets and conversion actions. Three things make this API unlike its neighbours. Access needs a developer token that Google approves, and calls made on behalf of an agency also carry a login customer id naming the manager account they run under. Reporting is not a set of endpoints but a query language, GAQL, so the queries themselves are part of the design rather than a parameter you pass. And versions retire on a published schedule, so an integration nobody maintains eventually stops working. fastn keeps the tokens, the version and the query surface current.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer authorise their own ad account, including agency-managed ones reached through a manager account.
Query performance with GAQL for exactly the campaign, ad group and keyword fields your product displays.
Change a budget or pause a campaign from your product, with the account it applied to recorded.
Send conversions back so bidding learns from what your product measured, not from the click alone.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reports which campaigns are pacing over budget this month for one account.
An agent pauses a keyword or campaign it has been permitted to change, and the change is attributed.
An agent explains a spend movement by querying the ad groups underneath it rather than guessing.
Example prompt
Which ad groups in this campaign spent the most last week, and what did each of them convert at?
Set up Google Ads in 4 steps
- 01Enable the Google Ads connector from your fastn dashboard.
- 02Have each customer authorise their own Google Ads account, so calls run under their credentials rather than a shared key.
- 03Decide which campaigns, ad groups, keywords and conversion actions your product needs, and note that reporting is queried with GAQL rather than delivered by webhook.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Google Ads integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Google Ads integration without building it. Your customers connect their own Google Ads 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 Google Ads update is not your on-call problem.
- One integration serves your product and your agents. The same governed Google Ads 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 CRMGoogle Ads integration FAQ
How do I add a Google Ads integration to my product?
Enable the Google Ads connector in your fastn dashboard, then let each customer authenticate their own Google Ads account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Google Ads client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Google Ads account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Google Ads 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 Google Ads 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 reports which campaigns are pacing over budget this month for one account.
Who maintains the Google Ads integration?
fastn does. When Google Ads 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 Google Ads 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 Google Ads?
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 Google Ads integration?
A common starting point: let a customer authorise their own ad account, including agency-managed ones reached through a manager account. 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 Google Ads integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Google Ads does not change your per-connector cost. You can start free with 3 connected accounts.
