  - name: Message
    description: >-
      Send a single WhatsApp message — text, media (image / video / document /
      audio) or a location pin — to one number, then read its delivery status or
      your message history. A file can be attached directly as a multipart
      `media` field or referenced by a public URL.
  - name: Template
    description: >-
      Create, list and manage your approved WhatsApp templates, and send a
      template to one number with your own header, body variables and button
      values. Use this for utility / marketing sends that need a pre-approved
      template — including one with a PDF / document header (pass the file's
      public URL as the header, e.g. from the Media endpoint).
  - name: Media
    description: >-
      Upload a file once (multipart / form-data, field name `file`, up to 16 MB)
      and get back a hosted public URL you can reuse across sends — for example
      a PDF to use as a document-header on a template, or an image on a message.
  - name: Contact
    description: >-
      Full create / read / update / delete over your contacts and leads,
      including search by number, tags and custom attributes.
  - name: ContactGroup
    description: >-
      Organise contacts into groups: create groups, list them, and add or remove
      members — handy for targeting broadcasts and campaigns.
  - name: Broadcast
    description: >-
      Send the same message to many contacts at once and track each broadcast's
      progress and per-recipient delivery.
  - name: Campaign
    description: >-
      Create, start, pause and monitor drip / marketing campaigns and their
      recipients.
  - name: Scheduled
    description: >-
      Schedule a WhatsApp send for a future time, list upcoming scheduled
      messages, and cancel one before it goes out.
  - name: AutoReply
    description: >-
      Manage keyword auto-replies — the automatic responses that fire when an
      inbound message matches a rule.
  - name: Flow
    description: >-
      Enroll a contact into an automation flow (chatbot) and manage your flows
      through the API.
  - name: Device
    description: >-
      List the WhatsApp numbers / devices connected to your workspace and check
      each one's connection status.
  - name: Webhook
    description: >-
      Register and manage webhook endpoints so Wachat POSTs real-time events
      (message received / sent / delivered / read / failed, plus campaign and
      contact events) to your server. When you set a signing secret each
      delivery carries an HMAC-SHA256 signature header you can verify.
  - name: Deal
    description: >-
      Manage sales-pipeline deals — create, list, update and move deals between
      stages.
  - name: Conversation
    description: >-
      Read your workspace inbox: list chat threads (conversations) and fetch the
      messages inside a thread.
  - name: Account
    description: Read your account details, plan, limits and message-credit usage.
