SalesLoft Common Errors
Overview
Quick reference for the most common SalesLoft REST API v2 errors. All errors return JSON with a message field. Rate limiting uses a cost-based system (600 cost/minute).
Error Reference
401 Unauthorized -- Invalid or Expired Token
{ "error": "Not authorized", "error_description": "The access token is invalid" }
Causes: Token expired, revoked, or wrong environment key.
Fix:
// Check if token works
const { data } = await api.get('/me.json').catch(err => {
if (err.response?.status === 401) {
console.error('Token invalid. Refreshing...');
return refreshAccessToken(storedRefreshToken);
}
throw err;
});
403 Forbidden -- Insufficient Scopes
{ "error": "Forbidden", "error_description": "Insufficient scope for this resource" }
Fix: Check app scopes in developer portal. Common issue: using user-level OAuth for team-level endpoints (cadences, team templates).
404 Not Found -- Wrong Endpoint or Deleted Resource
# Verify endpoint format -- all endpoints end with .json
curl -s -H "Authorization: Bearer $TOKEN" \
https://api.salesloft.com/v2/people/12345.json
# NOT /people/12345 (missing .json suffix)
422 Unprocessable Entity -- Validation Errors
{
"errors": [
{ "attribute": "email_address", "message": "is required" },
{ "attribute": "email_address", "message": "has already been taken" }
]
}
Common 422 causes:
| Field | Error | Solution |
|-------|-------|----------|
| email_address | required | Must include when creating a person |
| email_address | already taken | Use GET /people.json?email_addresses[]=x first |
| cadence_id | not active | Cadence must have current_state: 'active' |
| person_id | already enrolled | Check existing cadence memberships |
429 Too Many Requests -- Rate Limit Exceeded
X-RateLimit-Limit-Per-Minute: 600
X-RateLimit-Remaining-Per-Minute: 0
Retry-After: 42
SalesLoft uses cost-based rate limiting:
- Default: each request costs 1 point
- Pages 101-150: 3 points per request
- Pages 151-250: 8 points per request
- Pages 251-500: 10 points per request
- Pages 501+: 30 points per request
// Auto-retry with Retry-After header
api.interceptors.response.use(undefined, async (error) => {
if (error.response?.status === 429) {
const wait = parseInt(error.response.headers['retry-after'] || '60');
await new Promise(r => setTimeout(r, wait * 1000));
return api.request(error.config);
}
throw error;
});
5xx Server Errors
Fix: Retry with exponential backoff. Check status.salesloft.com for outages.
Quick Diagnostic
# 1. Verify token
curl -s -H "Authorization: Bearer $SALESLOFT_API_KEY" \

# 2. Check API status
curl -s https://status.salesloft.com/api/v2/status.json | jq '.status'

curl -v -H "Authorization: Bearer $SALESLOFT_API_KEY" \
'https://api.salesloft.com/v2/people.json?per_page=1'
# 4. Check rate limit remaining
curl -sI -H "Authorization: Bearer $SALESLOFT_API_KEY" \
https://api.salesloft.com/v2/people.json | grep -i ratelimit
