About

Universal.Operative.Sdk.WhatsApp provides acknowledged WhatsApp text and file messaging tools for Universal.Operative.Sdk.

The connection lifetime is selected independently:

  • TransientWhatsAppSessionProvider connects and disconnects around every invocation.
  • PersistentWhatsAppSessionProvider connects lazily and remains connected until disposed.
  • ConnectedWhatsAppSessionProvider borrows a client whose lifetime is managed by the host.

Each tool call supplies its recipient in one of these forms:

  • An international phone number containing digits only, including the country code: 15551234567. Do not include a leading +, spaces, or punctuation.
  • A user JID: 15551234567@s.whatsapp.net.
  • A group JID: 120363000000000@g.us.

Consumers can replace IWhatsAppRecipientResolver to apply aliases, allowlists, blocklists, directory lookup, or another application-specific policy.

Installation

dotnet add package Universal.Operative.Sdk.WhatsApp

Usage

var store = new FileWhatsAppAuthenticationStore(authenticationPath);
using var sessions = new TransientWhatsAppSessionProvider(store);
IReadOnlyList<ITool> tools = WhatsAppTools.Create(sessions);

The model calls the tool with both values:

{ "recipient": "15551234567", "message": "Are you coming tomorrow?" }

Files use a separate tool call:

{ "recipient": "15551234567", "file_path": "C:\\Reports\\report.pdf", "caption": "Latest report" }

WhatsAppSendFileTool infers common image, audio, video, and MIME types; unknown extensions are sent as documents. Its IWhatsAppFileAccess dependency can be replaced by consumers that need sandboxing, virtual storage, allowlists, or audit checks.

The authentication store must contain an already-paired linked-device identity. The tool does not pair accounts or expose credentials to the model.
