🚀 Installation

1. Clone the repository:

git clone https://github.com/diogobas/triangle-api.git
cd triangle-api

2. Install dependencies: pip install -r requirements.txt

3. Install the browser required by Playwright: playwright install chromium

💻 Usage Example

from triangle_api.client import TriangleClient
import os

# Using environment variables is recommended for security
USER = "[e-mail]"
PASSWORD = "your_secret_password"

# Instantiate the client
client = TriangleClient(username=USER, password=PASSWORD)

# Log in (opens browser on first run, uses cookies on next runs)
# headless=False lets you watch browser activity
data = client.login(headless=True)

print(f"Current Balance: $ {client.get_balance()}")
print(f"Available Credit: $ {data.get('availableCreditAmt')}")

🔒 Security and Persistence

To avoid raising suspicion from multiple logins, this wrapper uses Playwright's storage_state feature.

• After the first successful login, an auth_state.json file is created.
• On subsequent runs, the script tries to use these cookies to access the Dashboard directly.
• Important: Never commit auth_state.json to GitHub (it should already be in .gitignore).

🛠️ Development

If you want to contribute by mapping new endpoints (such as transactions or offers), follow these steps:

1. Log in to the CTFS website with Inspect mode (F12) open.
2. Filter by XHR/Fetch calls.
3. Look for endpoints such as retrieveTransactions or retrieveLoyalty.
4. Map the response JSON in the TriangleClient class.
