API03004: Request Too Large

What This Means​

The request you're sending exceeds the server's size limits. This typically happens when trying to send too much data at once.

Common Causes​

  • Large batch operations — Trying to sync too many records at once
  • Large images — Uploading oversized images
  • Too many items — Order with extremely many line items
  • Server limits — PHP or web server has low upload limits

How to Fix​

1. Reduce Request Size​

If syncing data:

  • Try syncing in smaller batches
  • The POS should handle this automatically
  • Wait for current sync to complete before starting another

2. Check Image Sizes​

If uploading images:

  • Resize images before uploading
  • Use compressed formats (JPEG vs BMP)
  • Most product images work well under 1MB

3. Split Large Orders​

If an order has many items:

  • Consider splitting into multiple orders
  • This is rare in normal POS usage

4. Increase Server Limits​

Contact your hosting provider or edit PHP settings:

// In php.ini or .htaccess
upload_max_filesize = 64M
post_max_size = 64M
max_input_vars = 5000

5. Check Web Server Limits​

Nginx or Apache may have their own limits:

  • client_max_body_size for Nginx
  • LimitRequestBody for Apache
