GraphQL AccessALPHA

Access JSON to CSV Converter through GraphQL to combine it with other API calls in a single request. Query only the json to csv converter data you need with precise field selection, and orchestrate complex data fetching workflows.

Test JSON to CSV Converter in the GraphQL Explorer to confirm availability and experiment with queries.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

GraphQL Endpoint
POST https://api.apiverve.com/v1/graphql
GraphQL Query Example
query {
  jsontocsv(
    input: {
      json: [{"name":"John Doe","age":30,"city":"New York"},{"name":"Jane Smith","age":25,"city":"Los Angeles"}]
      delimiter: ","
      include_header: true
    }
  ) {
    row_count
    column_count
    columns
    csv
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The JSON to CSV Converter API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call JSON to CSV Converter directly from browser-based applications without proxy servers.

CORS HeaderValueDescription
Access-Control-Allow-Origin*Accepts requests from any origin
Access-Control-Allow-Methods*Accepts any HTTP method
Access-Control-Allow-Headers*Accepts any request headers

Browser Usage: You can call JSON to CSV Converter directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

JSON to CSV Converter API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all JSON to CSV Converter users.

PlanRate LimitDescription
Free5 requests/minHard rate limit enforced - exceeding will return 429 errors
StarterNo LimitProduction ready - standard traffic priority
ProNo LimitProduction ready - preferred traffic priority
MegaNo LimitProduction ready - highest traffic priority

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each JSON to CSV Converter response includes headers to help you track your usage:

HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, JSON to CSV Converter returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for JSON to CSV Converter:

  • Monitor the rate limit headers to track your JSON to CSV Converter usage (Free plan only)
  • Cache json to csv converter responses where appropriate to reduce API calls
  • Upgrade to Pro or Mega for guaranteed no-throttle JSON to CSV Converter performance

Note: JSON to CSV Converter rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using JSON to CSV Converter on Free tier.

Error Codes

The JSON to CSV Converter API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution
200OKRequest successful, data returnedNo action needed - request was successful
400Bad RequestInvalid request parameters or malformed requestCheck required parameters and ensure values match expected formats
401UnauthorizedMissing or invalid API keyInclude x-api-key header with valid API key from dashboard
403ForbiddenAPI key lacks permission or insufficient creditsCheck credit balance in dashboard or upgrade plan
429Too Many RequestsRate limit exceeded (Free: 5 req/min)Implement request throttling or upgrade to paid plan
500Internal Server ErrorServer error occurredRetry request after a few seconds, contact support if persists
