Attio Upgrade & Migration
Overview
Attio has two API generations: v1 (legacy, deprecated) and v2 (current). This skill covers the v1-to-v2 migration, community SDK upgrade paths, and how to detect and adapt to API changes since Attio does not publish a traditional SDK changelog.
V1 to V2 Migration Reference
Endpoint Changes
| Operation | V1 Endpoint | V2 Endpoint |
|-----------|------------|------------|
| List objects | GET /v1/objects | GET /v2/objects |
| Query records | GET /v1/objects/{id}/records | POST /v2/objects/{slug}/records/query |
| Create record | POST /v1/objects/{id}/records | POST /v2/objects/{slug}/records |
| Get record | GET /v1/objects/{id}/records/{rid} | GET /v2/objects/{slug}/records/{rid} |
| List entries | GET /v1/lists/{id}/entries | POST /v2/lists/{slug}/entries/query |
| Create webhook | POST /v1/webhooks | POST /v2/webhooks |
| Search | N/A | POST /v2/records/search |
Key Differences
| Aspect | V1 | V2 |
|--------|----|----|
| Identifiers | UUIDs only | Slugs (preferred) or UUIDs |
| Record query | GET with query params | POST with JSON body (filters, sorts) |
| Filtering | Basic query params | Rich operators ($eq, $contains, $gt, $and, $or) |
| Pagination | page + per_page | limit + offset or cursor-based |
| Webhook payloads | Custom format | Consistent with v2 response shapes |
| Webhook filtering | None | Event-type and attribute-level filters |
Step 1: Update Base URL
// Before
const BASE = "https://api.attio.com/v1";
// After
const BASE = "https://api.attio.com/v2";
Step 2: Migrate Record Queries
// V1: GET with query params
const v1 = await fetch(
`${BASE}/objects/${objectId}/records?page=1&per_page=50`,
{ headers: { Authorization: `Bearer ${token}` } }
);
// V2: POST with filter body, using slug instead of UUID
const v2 = await fetch(
`${BASE}/objects/people/records/query`,
{
method: "POST",
headers: {
Authorization: `Bearer ${token}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
filter: {
email_addresses: { email_address: { $contains: "@example.com" } },
},
sorts: [{ attribute: "created_at", field: "created_at", direction: "desc" }],
limit: 50,
offset: 0,
}),
}
);
Step 3: Update Record Creation
// V1: values as flat key-value pairs
const v1Body = {
name: "Ada Lovelace",
email: "ada@example.com",
};
// V2: values nested under data.values, always arrays
const v2Body = {
data: {
values: {
name: [{ first_name: "Ada", last_name: "Lovelace", full_name: "Ada Lovelace" }],
email_addresses: ["ada@example.com"],
},
},
};
Step 4: Migrate Webhooks from V1 to V2
// V1 webhook event types
"object.record.created"
// V2 webhook event types
"record.created"
"record.updated"
"record.deleted"
"record.merged"
"list-entry.created"
"note.created"
"task.created"
// ... plus filtering support
V2 webhooks support event filtering to reduce volume:
await client.post("/webhooks", {
target_url: "https://yourapp.com/webhooks/attio",
subscriptions: [
{
event_type: "record.updated",
filter: {
// Only trigger for updates to the "stage" attribute on deals
$and: [
{ object: { $eq: "deals" } },
{ attribute: { $eq: "stage" } },
],
},
},
],
});
Community SDK Migration
Since there is no official Attio SDK, you may be using community packages:
attio-js (most popular community SDK)
# Check current version
npm list attio-js
# Upgrade
npm install attio-js@latest
// attio-js uses the v2 API natively
import { AttioClient } from "attio-js";
const client = new AttioClient({ accessToken: process.env.ATTIO_API_KEY });
const people = await client.records.query("people", { limit: 10 });
Direct fetch (recommended for control)
No upgrade risk -- you control the endpoint URLs directly. See attio-sdk-patterns for a typed wrapper.
Detecting API Changes
Attio does not publish a traditional changelog for the REST API. Monitor for changes:
// Save the OpenAPI spec hash and check periodically
import crypto from "crypto";
async function checkForApiChanges(): Promise<boolean> {
const spec = await fetch("https://docs.attio.com/openapi.json").then(r => r.text());
const hash = crypto.createHash("sha256").update(spec).digest("hex");
const previousHash = await readStoredHash(); // From file or DB
if (previousHash && hash !== previousHash) {
console.warn("Attio OpenAPI spec changed! Review for breaking changes.");
await storeHash(hash);
return true;
}
await storeHash(hash);
return false;
}
Migration Checklist
[ ] Base URL updated to /v2
[ ] Object references use slugs instead of UUIDs where possible
[ ] Record queries migrated from GET to POST with filter body
[ ] Record creation uses data.values wrapper with arrays
[ ] Webhook subscriptions recreated with v2 event types
[ ] Webhook handlers updated for v2 payload format
[ ] Pagination migrated from page/per_page to limit/offset
[ ] Error handling updated for v2 error response format
[ ] Tests updated and passing against v2 endpoints
[ ] OpenAPI spec monitoring configured for future changes
Error Handling
| Migration issue | Symptom | Fix |
|----------------|---------|-----|
| Old v1 URL | 404 on all calls | Update base URL to /v2 |
| UUID instead of slug | 404 on object endpoints | Use api_slug from GET /v2/objects |
| Flat values (v1 format) | 422 validation error | Wrap in { data: { values: { ... } } } |
| Old webhook event types | Webhook never fires | Recreate with v2 event types |
| Old pagination params | Ignored, only first page returned | Switch to limit + offset |
