Transforms phone numbers into direct WhatsApp chat links for easy conversations.

whatsapp-linkify

whatsapp-linkify is a Python package that transforms phone numbers into direct WhatsApp chat links. It allows users to input a phone number or text containing phone numbers, and processes this input to generate structured WhatsApp chat URLs. This is especially useful for businesses, customer support teams, or anyone needing quick access to WhatsApp chats without manually formatting links.

Installation

Install the package via pip:

pip install whatsapp_linkify

Usage

Here's a basic example of how to use the package:

from whatsapp_linkify import whatsapp_linkify

results = whatsapp_linkify(
    user_input="Call me at [phone] or [phone].",
)
print(results)

Parameters

• user_input: str
  The input text containing phone numbers to process.

• llm: Optional[BaseChatModel]
  An optional language model instance to use. If not provided, the default ChatLLM7 from langchain_llm7 is used.

• api_key: Optional[str]
  An optional API key for LLM7. If not provided, it will be fetched from the environment variable LLM7_API_KEY.

LLM Compatibility and Customization

The package uses ChatLLM7 from the langchain_llm7 package (https://pypi.org/project/langchain-llm7/).
Developers can pass their own language model instances to whatsapp_linkify, supporting models such as:

• OpenAI (via langchain_openai.ChatOpenAI)

  from langchain_openai import ChatOpenAI
  from whatsapp_linkify import whatsapp_linkify
  
  llm = ChatOpenAI()
  response = whatsapp_linkify(user_input, llm=llm)
  

• Anthropic (via langchain_anthropic.ChatAnthropic)

  from langchain_anthropic import ChatAnthropic
  from whatsapp_linkify import whatsapp_linkify
  
  llm = ChatAnthropic()
  response = whatsapp_linkify(user_input, llm=llm)
  

• Google Generative AI (via langchain_google_genai.ChatGoogleGenerativeAI)

  from langchain_google_genai import ChatGoogleGenerativeAI
  from whatsapp_linkify import whatsapp_linkify
  
  llm = ChatGoogleGenerativeAI()
  response = whatsapp_linkify(user_input, llm=llm)
  

The default rate limits for LLM7’s free tier are sufficient for most use cases. For higher limits, users can obtain an API key from https://token.llm7.io/ and pass it via the api_key parameter or environment variable.
