# API03004: Request Too Large

## What This Means[​](#what-this-means "Direct link to 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[​](#common-causes "Direct link to 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[​](#how-to-fix "Direct link to How to Fix")

### 1. Reduce Request Size[​](#1-reduce-request-size "Direct link to 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[​](#2-check-image-sizes "Direct link to 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[​](#3-split-large-orders "Direct link to 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[​](#4-increase-server-limits "Direct link to 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[​](#5-check-web-server-limits "Direct link to 5. Check Web Server Limits")

Nginx or Apache may have their own limits:

* `client_max_body_size` for Nginx
* `LimitRequestBody` for Apache
