notify-to-cisco-webex 0.0.4

Send messages and files to Cisco Webex.

notify-to-cisco-webex

Overview

A small Python module and CLI for sending messages (and file attachments) to Cisco Webex. It can be used both as a Python library (programmatic API) and as a command-line tool.

Key features

• Send text or markdown messages.
• Attach files (one file per Webex message; when multiple files are supplied the tool sends one message per file and includes the message body only on the first send).
• Support for programmatic file attachments using local filesystem paths or Base64-encoded file objects (when used as a Python module).
• Configuration via constructor arguments, OS environment variables, or a .env file (priority: constructor args > environment > .env).
• TLS verification toggle, proxy support, and request timeout.
• Returns API responses as parsed JSON when operations succeed.
• Minimal external dependencies: dotenv and httpx.

Requirements

• Python 3.14+ (project metadata)
• External packages:
  • dotenv (for loading .env)
  • httpx (for HTTP)
• (Dev) pytest for running tests

Installation

Install the package and its dependencies. Examples:

• Editable install for development:

python -m pip install -e .

• Install production deps (after building or from PyPI if published):

python -m pip install .

Configuration / Environment variables

The following environment variables (or entries in a .env file) are supported:

• WEBEX_ACCESS_TOKEN — Webex access token (required unless supplied to constructor/CLI).
• WEBEX_ROOM_ID — Room ID to post messages to (optional if WEBEX_TO_EMAIL is used).
• WEBEX_TO_EMAIL — Recipient email address (optional if WEBEX_ROOM_ID is used).
• WEBEX_PROXY — Optional HTTP proxy URL (passed to httpx).

Priority for configuration when creating a Webex object:

1. Constructor arguments
2. OS environment variables
3. .env file

Note: If both room_id and to_email are provided, room_id takes precedence.

Using the Python module

Import and use the Webex class to send messages programmatically.

Example:

from notify_to_cisco_webex.notify_to_cisco_webex import Webex

# Create a client (constructor args override environment)
client = Webex(access_token="MY_TOKEN", room_id="ROOM_ID")

# Send a message (no attachments)
response = client.send_message(message="Hello from Python!", format="markdown")
print(response)

# Send message with multiple attachments (will POST one message per file;
# the message body is included only for the first file)
files = ["./image1.png", "./doc.pdf"]
responses = client.send_message(message="Files attached", format="markdown", files=files)
print(responses)

API notes:

• format accepts "markdown" or "text".
• Attachments:
  • CLI usage (via --file): supply one or more local filesystem paths. Example: --file ./image.png --file ./doc.pdf. The CLI only accepts filesystem paths.
  • Python module usage (programmatic send_message): files may be provided in any of the following forms:
    • A list of local filesystem path strings: ["/path/to/a.png", "/path/to/b.pdf"]
    • A list of objects (dicts), each containing filename and content (base64-encoded bytes). Example:

      [{"filename": "a.txt", "content": "<base64>"}, {"filename": "b.png", "content": "<base64>"}]
      

      When object entries are used, the library creates temporary files from the decoded content and attaches them.
    • A single base64-encoded JSON string representing the list of objects described above. This is useful when passing the payload through an environment variable or other string channel. Example JSON before encoding:

      [
          { "filename": "a.txt", "content": "<base64>" },
          { "filename": "b.png", "content": "<base64>" }
      ]
      

      Encode that JSON using base64 (UTF-8) and pass the resulting string as the files argument to send_message.
  • Note: Base64 object attachments are supported only when using the Python module API (programmatic calls). CLI remains unchanged and only accepts local paths.
• When multiple files are passed, the return value is a list of response JSON objects (one per sent message). When a single file or no files is used, a single dict is returned for convenience.
• Errors raise WebexError with a descriptive message.

Using the CLI

A CLI entrypoint is provided. There are multiple ways to run the CLI depending on how you have installed or are running the package. All of the following are supported after installation:

• Module invocation (short module): python -m notify_to_cisco_webex
• Module invocation (explicit module file): python -m notify_to_cisco_webex.notify_to_cisco_webex
• Installed console script (underscore name): notify_to_cisco_webex — installed when you create a console-script entry with this name
• Installed console script (hyphenated name): notify-to-cisco-webex — the hyphenated command is provided by the package's console script entry (recommended for shell ergonomics)

Examples

Run via python -m:

python -m notify_to_cisco_webex -t "$WEBEX_ACCESS_TOKEN" -r "ROOM_ID" -m "Hello from -m" --file ./image.png

Run via direct module path:

python -m notify_to_cisco_webex.notify_to_cisco_webex -t "$WEBEX_ACCESS_TOKEN" -r "ROOM_ID" -m "Hello from direct module" --file ./image.png

Run via installed underscore console script (after pip install . or pip install -e .):

notify_to_cisco_webex -t "$WEBEX_ACCESS_TOKEN" -r "ROOM_ID" -m "Hello from underscore script" --file ./image.png

Run via installed hyphenated console script (after pip install . or pip install -e .):

notify-to-cisco-webex -t "$WEBEX_ACCESS_TOKEN" -r "ROOM_ID" -m "Hello from hyphenated script" --file ./image.png

CLI options

• -t, --token — Webex access token (overrides env/.env)
• -r, --room-id — Room ID to send the message to
• -e, --to-email — Recipient email address (used when room id is not set)
• -m, --message — Message body text
• -f, --format — Message format, text or markdown (default: Markdown)
• --timeout — HTTP request timeout in seconds (default: 10.0)
• --no-verify — Disable SSL certificate verification (flag)
• -v, --verbose — Enable verbose logging (flag)
• -p, --proxy — HTTP proxy URL
• --file — Attach a file. This option can be specified multiple times to attach multiple files (note: one file per Webex message). CLI only accepts local filesystem paths for --file.

CLI output:

• Printed JSON is pretty-printed for human readability when the operation succeeds.
• On error, the CLI prints a JSON object containing an error key and exits with a non-zero status.

Examples

Send a simple message using environment variables:

export WEBEX_ACCESS_TOKEN="TOKEN"
export WEBEX_ROOM_ID="ROOM_ID"
python -m notify_to_cisco_webex --message "Hello"

Send multiple files (the message is included in the first message only):

notify-to-cisco-webex --token "TOKEN" --room-id "ROOM_ID" \
  --message "Here are the files" --file ./1.jpg --file ./2.pdf

Testing

Run the automated tests using pytest:

python -m pip install -e '.[dev]'
pytest -q

Project structure highlights

• notify_to_cisco_webex/notify_to_cisco_webex.py — Main implementation (contains the Webex class and a main() CLI entry).
• tests/ — pytest test cases.

Error handling

• The module raises WebexError for invalid configuration, file errors, HTTP errors, and non-JSON responses.
• The CLI prints error information as JSON and returns a non-zero exit code on failures.
