Connect Python sites to ErrorNotifier

1. Set environment variables

# PowerShell
$env:ERRORNOTIFIER_PROJECT_KEY = "enpk_your_public_project_key"
$env:ERRORNOTIFIER_ENDPOINT = "https://errornotifier.com/wp-json/errornotifier/v1/store"
$env:ERRORNOTIFIER_BASE_URL = "https://errornotifier.com"
$env:ERRORNOTIFIER_ENVIRONMENT = "production"
$env:ERRORNOTIFIER_SERVICE_NAME = "billing-worker"
$env:ERRORNOTIFIER_RELEASE = "billing-2026.06.09.1"

# Linux/macOS shell
export ERRORNOTIFIER_PROJECT_KEY="enpk_your_public_project_key"
export ERRORNOTIFIER_ENDPOINT="https://errornotifier.com/wp-json/errornotifier/v1/store"
export ERRORNOTIFIER_BASE_URL="https://errornotifier.com"
export ERRORNOTIFIER_ENVIRONMENT="production"
export ERRORNOTIFIER_SERVICE_NAME="billing-worker"
export ERRORNOTIFIER_RELEASE="billing-2026.06.09.1"

2. Capture exceptions and messages

import errornotifier

try:
    raise RuntimeError("Worker job failed")
except RuntimeError as exc:
    errornotifier.capture_exception(
        exc,
        tags={"queue": "billing"},
        request={"url": "/jobs/billing/reconcile"},
    )

errornotifier.capture_message(
    "Nightly billing job finished with retries",
    severity="warning",
    tags={"queue": "billing"},
)

3. Attach Python logging

import logging
from errornotifier import ErrorNotifierLoggingHandler

logger = logging.getLogger("billing-worker")
logger.setLevel(logging.INFO)
logger.addHandler(ErrorNotifierLoggingHandler(level=logging.ERROR))

try:
    1 / 0
except ZeroDivisionError:
    logger.exception("billing reconciliation failed")

4. Flask application sample

from flask import Flask, got_request_exception, request
import errornotifier

app = Flask(__name__)

def report_error(sender, exception, **extra):
    errornotifier.capture_exception(
        exception,
        request={
            "url": getattr(request, "url", ""),
            "method": getattr(request, "method", ""),
        },
        tags={"framework": "flask"},
    )

got_request_exception.connect(report_error, app)

5. Raw requests.post fallback

import os
import requests

# Raw HTTPS fallback using the same ingest contract.
response = requests.post(
    "https://errornotifier.com/wp-json/errornotifier/v1/store",
    headers={
        "X-ErrorNotifier-Key": os.environ["ERRORNOTIFIER_PROJECT_KEY"],
        "Content-Type": "application/json",
    },
    json={
        "platform": "python",
        "severity": "error",
        "message": "Worker job failed",
        "release": os.getenv("ERRORNOTIFIER_RELEASE", ""),
        "environment": os.getenv("ERRORNOTIFIER_ENVIRONMENT", "production"),
        "tags": {"service": "worker"},
    },
    timeout=5,
)
response.raise_for_status()
