Attio
Add Attio to your product for your customers, and give your AI agents governed access to it.
Attio is a CRM built as a data model rather than as a fixed set of screens, so a workspace has objects, companies, people and deals to begin with and whatever else that team decided to create, each with its own attributes. Discovering that structure at connect time is not an optimisation here, it is the only way to write correctly, because two customers on the same plan can have genuinely different schemas. The detail integrations most often get wrong is lists. A list is not a saved filter, it holds its own entries with their own attributes, so the stage a deal is at can live on the list entry rather than on the record itself, and reading only the record will miss it. Notes, tasks and comments hang off records, and changes come back as events rather than needing a poll. fastn keeps each workspace's authorisation per tenant.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own Attio workspace and read its object and attribute definitions before writing anything.
Create and update records on custom objects, not only on companies, people and deals.
Work with list entries and their own attributes, so a pipeline stage held on the list is not quietly missed.
React to record and list changes as events, so your product responds when a deal moves rather than on a schedule.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a company with its people, notes and open deals before answering a question about the account.
An agent adds a record to a list and sets the attributes that list requires, with the write attributed.
An agent reports which deals have not moved stage in a fortnight and what the last note on each said.
Example prompt
Which deals in this Attio list have gone two weeks without an update, and what was the last note on each?
Set up Attio in 4 steps
- 01Enable the Attio connector in your fastn dashboard.
- 02Have each customer authorise their own workspace with the narrowest scopes your features need.
- 03Read the workspace's objects, attributes and lists at connect time, then map the ones your product uses.
- 04Call it from your product and expose the same governed connection to your agents.
Why teams use the Attio integration
What you get by embedding it with fastn instead of building it yourself.
- Ship an Attio integration without building it. Your customers connect their own Attio 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 an Attio update is not your on-call problem.
- One integration serves your product and your agents. The same governed Attio 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.

How do I add an Attio integration to my product?
Enable the Attio connector in your fastn dashboard, then let each customer authenticate their own Attio account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Attio client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Attio account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Attio 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 Attio 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 reads a company with its people, notes and open deals before answering a question about the account.
Who maintains the Attio integration?
fastn does. When Attio 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 Attio 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 Attio schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from Attio, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in Attio do not drift apart.
What can I build with the Attio integration?
A common starting point: let each customer connect their own Attio workspace and read its object and attribute definitions before writing anything. 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 Attio integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Attio does not change your per-connector cost. You can start free with 3 connected accounts.
