Use Truto's Unified CRM API to upsert company records via assert endpoints, matching on domain to prevent duplicates, and update custom attributes like current plan or revenue tier. - **Push product usage signals to drive sales workflows** — Product analytics and PLG platforms can sync high-intent user actions — like feature adoption or team invites — directly into Attio as contact or deal attribute updates. This lets your customers' sales teams act on product-qualified leads without leaving their CRM. - **Log support interactions on CRM records for full customer context** — Customer support platforms can write ticket summaries, escalation notes, and resolution details as notes on Attio company or person records. Sales teams get instant visibility into active support issues tied to their accounts and deals. - **Automate outbound campaign enrollment from CRM lists** — Outbound and marketing automation tools can read Attio lists and entries to pull segmented audiences for campaigns, then write back engagement statuses like replied, bounced, or meeting booked — giving CRM users a live view of campaign performance. - **Enrich CRM records with third-party data on creation** — Data enrichment providers can listen for new company or person records via Attio webhooks, run enrichment workflows, and write firmographic or technographic data back to custom attributes — all through Truto without managing Attio's API directly. ## What you can build - **Idempotent company and contact upserts** — Use Attio's assert endpoints via Truto to create-or-update companies by domain and people by email address, eliminating duplicate records when syncing data from your product. - **Real-time deal stage automation** — Move deals and list entries between pipeline stages automatically by updating entry statuses when key events occur in your platform — like a contract signature or trial expiration. - **Custom attribute sync with historical tracking** — Write product metrics, health scores, or billing data to Attio custom attributes and leverage attribute value endpoints to expose how those values changed over time. - **Automated task creation for account managers** — Create tasks in Attio assigned to specific workspace members when your product detects an actionable event, like a customer upgrading, a usage spike, or a renewal approaching. - **Dynamic field mapping using schema discovery** — Query Attio's objects and attributes at runtime to let your end users map your product's data fields to their specific Attio setup, supporting custom objects and bespoke attribute configurations. - **Contextual note and comment logging on CRM threads** — Attach structured notes to company, person, or deal records and post comments on active threads so your product's activity history appears natively inside your customers' Attio workspace. ## FAQs ### What authentication method does the Attio integration use? Attio uses OAuth 2.0 for third-party integrations. Truto handles the full OAuth flow, token storage, and refresh cycle so your end users can connect their Attio workspace with a single click. ### How do I avoid creating duplicate records when syncing data to Attio? Attio provides assert endpoints (available for companies, people, deals, users, entries, and more) that perform idempotent upserts. You specify a matching attribute — like domain for companies or email_address for people — and Attio will update the existing record or create a new one. These are fully supported through Truto. ### Can I read and write custom fields and custom objects in Attio? Yes. You can use list_all_attio_attributes and list_all_attio_objects to discover your end user's custom schema at runtime, then read and write custom attribute values on any record. Truto's Unified CRM Fields resource also maps to Attio attributes. ### What's the difference between updating and overwriting multiselect attributes? Attio's standard update endpoints prepend new values to multiselect attributes, preserving existing selections. If you need to fully replace them, use the overwrite endpoints (e.g., attio_records_overwrite or attio_entries_overwrite) which replace the attribute value entirely. ### Does the integration support webhooks for real-time event triggers? Yes. You can create, list, update, and delete Attio webhooks through Truto. This lets your product subscribe to events like record creation or attribute changes in your end user's Attio workspace and react in real time. ### Which Truto Unified APIs map to Attio? Attio is supported under the Unified CRM API (covering Accounts, Contacts, Associations, Fields, Notes, Opportunities, Tasks, and Users) and the Unified User Directory API (covering Users and Roles). You can use either the unified models for cross-CRM compatibility or Attio-specific proxy endpoints for full API coverage. ## Related reading - [Connect Attio to Claude: Automate Pipeline Management via MCP](https://truto.one/blog/connect-attio-to-claude-automate-pipeline-management-and-collaboration/) — Step-by-step engineering guide to connecting Attio to Claude using a managed MCP server.
