Error Response Structure
The IXO Spatial Web API provides informative error responses in JSON format:
Response Fields
- code: HTTP status code
- message: Human-readable error description
- details: Additional error information
Best Practices
Use HTTP Status Codes
Use HTTP Status Codes
Rely on HTTP status codes to understand error types and handle them appropriately.
Implement Retry Logic
Implement Retry Logic
For 5xx errors, implement retry logic with exponential backoff.
Validate Input
Validate Input
Validate all input parameters before sending requests to minimize 400 errors.
Respect Rate Limits
Respect Rate Limits
Monitor and respect rate limits to avoid 429 errors.
Common Error Solutions
400 Bad Request
Solution: Double-check request syntax and parameters
401 Unauthorized
Solution: Verify access token and re-authenticate if needed
403 Forbidden
Solution: Verify user permissions and roles
500 Internal Server Error
