Cluster C1: JSON Ecosystem
How to validate JSON before API requests
The fastest way to reduce API incident noise is to validate payloads before they leave client code or job workers. A lightweight preflight checklist catches syntax, schema, and encoding issues before they become retries and alerts.
Validation checkpoints that matter
- Run strict parser validation after formatting.
- Check required fields and type expectations against the API contract.
- Verify UTF-8 and remove hidden control characters from copied input.
- Compare a minified transport payload with expected schema examples.
Practical input/output example
Input
{
"id": "42",
"enabled": "true"
}Output
schema check: failed reason: enabled must be boolean
