Attio Common Errors

Attio Common Errors

Overview

Every Attio API error returns a consistent JSON body. This skill covers the real error codes, response format, and proven solutions for each.

Attio Error Response Format

All errors from https://api.attio.com/v2 return this structure:

{
  "status_code": 429,
  "type": "rate_limit_error",
  "code": "rate_limit_exceeded",
  "message": "Rate limit exceeded, please try again later"
}

Fields: status_code (HTTP status), type (error category), code (specific code), message (human-readable).

Error Reference

400 Bad Request -- invalid_request

{ "status_code": 400, "type": "invalid_request_error", "code": "invalid_request", "message": "..." }

Common causes and fixes:

Diagnostic:

# List attributes to verify types
curl -s https://api.attio.com/v2/objects/people/attributes \
  -H "Authorization: Bearer ${ATTIO_API_KEY}" \
  | jq '.data[] | {slug: .api_slug, type: .type, required: .is_required}'

401 Unauthorized -- authentication_error

{ "status_code": 401, "type": "authentication_error", "code": "invalid_api_key", "message": "..." }

Diagnostic:

# Verify token works
curl -s -o /dev/null -w "%{http_code}" \
  https://api.attio.com/v2/objects \
  -H "Authorization: Bearer ${ATTIO_API_KEY}"
# Should return 200

403 Forbidden -- insufficient_scopes

{ "status_code": 403, "type": "authorization_error", "code": "insufficient_scopes",
  "message": "Token requires 'record_permission:read-write' scope" }

Fix: Edit token in Settings > Developers > Access tokens, add missing scope, save. No need to regenerate.

404 Not Found -- not_found

{ "status_code": 404, "type": "not_found_error", "code": "not_found", "message": "..." }

409 Conflict -- conflict

Occurs when creating a record with a value that conflicts with an existing unique attribute (e.g., duplicate email or domain).

Fix: Use PUT (assert) instead of POST to upsert:

// Assert: create or update matching record
await client.put("/objects/people/records", {
  data: {
    values: {
      email_addresses: ["existing@example.com"],
      name: [{ first_name: "Updated", last_name: "Name" }],
    },
  },
});

422 Unprocessable Entity -- validation_error

429 Too Many Requests -- rate_limit_exceeded

{
  "status_code": 429,
  "type": "rate_limit_error",
  "code": "rate_limit_exceeded",
  "message": "Rate limit exceeded, please try again later"
}

Attio uses a sliding window algorithm with a 10-second window. The Retry-After response header contains a date (usually the next second).

Immediate fix:

if (res.status === 429) {
  const retryAfter = res.headers.get("Retry-After");
  const waitMs = retryAfter
    ? new Date(retryAfter).getTime() - Date.now()
    : 1000;
  await new Promise((r) => setTimeout(r, Math.max(waitMs, 100)));
  // Retry the request
}

See attio-rate-limits for full backoff and queue patterns.

500+ Server Error

Rare, but Attio may reduce rate limits during incidents. Always implement retry for 5xx.

Quick Diagnostic Script

#!/bin/bash
echo "=== Attio Diagnostic ==="
echo -n "Auth: "
curl -s -o /dev/null -w "%{http_code}" \
  https://api.attio.com/v2/objects \
  -H "Authorization: Bearer ${ATTIO_API_KEY}"
echo ""

echo -n "Status page: "
curl -s https://status.attio.com/api/v2/status.json | jq -r '.status.description'

echo "Objects:"
curl -s https://api.attio.com/v2/objects \
  -H "Authorization: Bearer ${ATTIO_API_KEY}" \
  | jq -r '.data[].api_slug' 2>/dev/null || echo "FAILED"

Error Handling Pattern

import { AttioApiError } from "./client";

async function handleAttioError(err: AttioApiError): Promise<void> {
  switch (err.statusCode) {
    case 401: throw new Error("Attio auth failed -- check ATTIO_API_KEY");
    case 403: throw new Error(`Missing scope: ${err.message}`);
    case 404: console.warn("Resource not found, may have been deleted");  break;
    case 409: console.warn("Conflict -- use PUT to upsert instead");     break;
    case 429: /* handled by retry wrapper */ break;
    default:  throw err;
  }
}
