FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

💳 GatePay
The Payment Gateway Library That Actually Makes Sense
Stop wrestling with payment integrations. Start building.
Small Libraries BIG IMPACT!
GatePay is not just another payment gateway wrapper. It's a deterministic, traceable, and swappable payment processing framework designed to make your life easier. No need to read hundreds files of core code to understand how to process a payment. No more 3 AM debugging sessions trying to figure out why your transaction failed. With GatePay, you get a clear, predictable flow that works the same way for every gateway implementation.
😤 The Problem
Every developer who has integrated payment gateways knows the pain:
| 😱 The Reality | 💀 What You Get |
|---|---|
| Setup Hell | 500+ lines of config before your first transaction |
| Spaghetti State | if-else nightmare tracking payment status |
| Debug Despair | "Where did my transaction fail?" - You, at 3 AM |
| Copy-Paste Chaos | Every gateway = rewrite everything from scratch |
| Documentation Maze | 47 tabs open, still confused |
| Ambiguous Everything | Is it PAID, paid, success, SUCCESS, or 1? |
🤯 Learning Curve Hell
✨ The Solution
GatePay is built on one principle: Deterministic Payment Processing
🎯 What We Need To Solve
| Problem | GatePay Solution |
|---|---|
| Complex Setup | 5 lines to process your first payment |
| Untraceable Flows | Every state change is logged & trackable |
| Gateway Lock-in | Swap gateways with zero code changes |
| State Chaos | Clear enum states: PENDING, SUCCESS, ERROR |
| Logging Nightmare | PSR-3 logger integration built-in |
| HTTP Headaches | PSR-7/PSR-17/PSR-18 compliant - use ANY HTTP client |
| Ambiguous Responses | Consistent @attributes + @value format for XML |
🚀 Quick Start
No 500-line setup. No config files. No magic strings.

🎓 Learning Path
| Step | Time | What You Learn |
|---|---|---|
| 1 | 5 min | Process your first transaction |
| 2 | 15 min | Understand Transaction States |
| 3 | 30 min | Create a custom Gateway |
| 4 | 1 hour | Master Actions & Processors |
Prerequisites: Basic understanding of PSR-7, PSR-17, PSR-18

🤝 Philosophy
Payment processing should be:
- ✅ Predictable - Same input = Same output
- ✅ Traceable - Know exactly what happened and when
- ✅ Swappable - Change gateways without rewriting code
- ✅ Debuggable - Find issues in minutes, not hours
- ✅ Learnable - Understand in a day, master in a week
