Google Contacts

Add Google Contacts to your product for your customers, and give your AI agents governed access to it.

Embed a Google Contacts integration so your customers can keep the contacts in their own Google account in step with the records in your product, rather than re-typing them. Each customer authorises their own account with OAuth, so their contacts stay theirs and your product only touches what they granted. fastn handles per-user OAuth, token refresh, pagination, and API upkeep.

In your product

Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.

Let customers import their own contacts and contact groups into your product, mapped to your fields.

Write a contact back so someone added in your product also appears in their address book.

Keep names, emails, phone numbers, and organisation details in step both ways.

Refresh contacts on a schedule so your product is not working from a one-time import.

For your AI agents

Governed, audited access for the agents you build, through the MCP server.

An agent looks up a contact's details before drafting a message.

An agent adds or updates a contact within governed permissions, with the action logged.

An agent checks whether a person already exists before creating a duplicate.

Example prompt

Find contacts with no email address and any duplicates that share the same phone number.

Set up Google Contacts in 4 steps

  1. 01Open the Google Contacts connector from your fastn dashboard.
  2. 02Have each customer authenticate their own Google account with OAuth.
  3. 03Map the contact fields and groups your product reads and writes, then enable actions and triggers.
  4. 04Call them from your product, or expose them to an agent through the MCP server.

Why teams use the Google Contacts integration

What you get by embedding it with fastn instead of building it yourself.

  • Ship a Google Contacts integration without building it. Your customers connect their own Google Contacts account inside your product and work their accounts, contacts and opportunities there, with no per-customer code on your side.
  • Handle the part that actually costs time: every CRM instance is customised, so standard objects are never the whole story. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Google Contacts update is not your on-call problem.
  • One integration serves your product and your agents. The same governed Google Contacts connection powers in-product features and gives AI agents scoped, audited access, so you keep customer records aligned between your product and the CRM each customer already runs without wiring it twice.

Google Contacts integration FAQ

How do I add a Google Contacts integration to my product?

Enable the Google Contacts connector in your fastn dashboard, then let each customer authenticate their own Google Contacts account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Google Contacts 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 Contacts account?

Yes. Every connection is scoped to the individual customer, so each authorises their own Google Contacts account and only ever sees their own accounts, contacts and opportunities. 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 Contacts 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 looks up a contact's details before drafting a message.

Who maintains the Google Contacts integration?

fastn does. When Google Contacts 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.

Does the Google Contacts integration support custom fields and custom objects?

Yes. CRM instances are heavily customised, so field and object mapping is configuration rather than code. Each customer maps their own fields during setup, which means onboarding a customer with an unusual Google Contacts schema does not require a deploy on your side.

Can records sync both ways?

Yes. You can read from Google Contacts, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in Google Contacts do not drift apart.

What can I build with the Google Contacts integration?

A common starting point: import their own contacts and contact groups into your product, mapped to your fields. 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 Contacts integration cost?

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Google Contacts does not change your per-connector cost. You can start free with 3 connected accounts.
