# Start WhatsApp label refresh

> Starts a new read of the labels on WhatsApp without blocking the request.
The response only confirms that the refresh was started or that a refresh is already in progress.
To get the updated list, query `GET /labels` afterwards.

The refresh also updates the associations between labels and chats. When
there are changes, the `chat_labels` webhook may report the updated data.

The response includes a `request_id`, repeated in the `history` webhooks (`labels` and `chat_labels`) of that refresh. If a refresh is already in progress, the `request_id` is that one's.

Recommended usage:
- try first with `force=false`
- if that does not bring the labels correctly, try `force=true`
- use `force=true` only as a correction attempt, because it performs a heavier refresh




## OpenAPI

````yaml /openapi-en.json post /labels/refresh
openapi: 3.1.0
info:
  title: WppFy -  WhatsApp API
  version: 1.0.0
  description: >
    API for managing WhatsApp instances and communications.


    ## Important Recommendation: WhatsApp Business

    **It is HIGHLY RECOMMENDED to use WhatsApp Business accounts** instead of
    regular WhatsApp for integration; regular WhatsApp may present
    inconsistencies, disconnections, limitations, and instability when used with
    our API.


    ## Authentication

    - Regular endpoints require a 'token' header with the instance token


    ## Instance States

    Instances can be in the following states:

    - `disconnected`: Disconnected from WhatsApp

    - `connecting`: Connection in progress

    - `connected`: Successfully connected and authenticated
servers:
  - url: https://api.wppfy.com
security:
  - token: []
tags:
  - name: Instance
    description: |
      Operations related to an instance's lifecycle, such as connecting,
      disconnecting, and checking status.
  - name: Proxy
    description: >
      WppFy uses an internal proxy by default.

      You can keep this default, configure your own proxy via `proxy_url`, or
      use your Android phone as a proxy by installing the app from
      https://github.com/WppFy/silver_proxy_apk (direct APK:
      https://github.com/WppFy/silver_proxy_apk/raw/refs/heads/main/silver_proxy.apk).

      If nothing is sent, we keep using the internal proxy. IPs are Brazilian;
      for international clients, consider a proxy in the client's region.
  - name: Profile
    description: |
      Operations related to the WhatsApp instance profile, such as changing
      the profile name and picture.
  - name: Business
    description: |
      ⚠️ **EXPERIMENTAL** - Endpoints not yet fully tested.

      Operations related to the WhatsApp Business business profile.
      Allows querying and updating business profile data such as description,
      address, email, categories, and managing the product catalog.

      **Requirements:**
      - The currently connected account must be a **WhatsApp Business** account
      - Personal WhatsApp accounts do not have a business profile

      **Note:** These endpoints may not work as expected.
      Report any problems found.
  - name: Calls
    description: |
      Operations related to WhatsApp calls.
      Allows making and rejecting calls programmatically.
  - name: Send Message
    description: >
      Endpoints for sending WhatsApp messages with different content types.


      ## Common Optional Fields


      All message sending endpoints support the following optional fields:


      - **`delay`** *(integer)*: Delay in milliseconds before sending
        - During the delay, "Typing..." or "Recording audio..." will appear depending on the type
        - Example: `5000` (5 seconds)

      - **`readchat`** *(boolean)*: Mark chat as read after sending
        - Removes the unread message counter from the chat
        - Example: `true`

      - **`readmessages`** *(boolean)*: Mark last received messages as read
        - Marks the last 10 **received** messages (not sent by you) as read
        - Useful to confirm reading pending messages before replying
        - Different from `readchat` which only removes the unread counter
        - Example: `true`

      - **`replyid`** *(string)*: ID of the message to reply to
        - Creates a reply linked to the original message
        - Support varies by message type
        - Example: `"3A12345678901234567890123456789012"`

      - **`mentions`** *(string)*: Numbers to mention (only for group sending)
        - Specific numbers: `"5511999999999,5511888888888"`
        - Mention all: `"all"`

      - **`forward`** *(boolean)*: Marks the message as forwarded in WhatsApp
        - Adds the "Forwarded" indicator to the message
        - Example: `true`

      - **`track_source`** *(string)*: Message tracking source
        - Identifies the system or source sending the message
        - Useful for integrations (e.g., "chatwoot", "crm", "chatbot")
        - Example: `"chatwoot"`

      - **`track_id`** *(string)*: ID for message tracking
        - Free identifier to track the message in external systems
        - Allows correlating messages between different platforms
        - **Note**: The system accepts duplicate values - there is no uniqueness validation
        - Use the same ID in multiple messages if it makes sense for your integration
        - Example: `"msg_123456789"`

      ### Sending to Groups

      - **`number`** *(string)*: To send a message to a group, use the group ID
      ending with `@g.us`
        - Example: `"120363012345678901@g.us"`
        - **How to get the Group ID:**
          - Use the `chatid` from the webhook received when someone sends a message in the group
          - Use the `GET /group/list` endpoint to list all groups and their IDs

      ## Available Placeholders


      All message sending endpoints support dynamic placeholders for automatic
      personalization:


      ### Name Fields

      - **`{{name}}`**: Consolidated chat name, using the first available
      option:
        1. Lead name (`lead_name`)
        2. Lead full name (`lead_fullName`)
        3. WhatsApp contact name (`wa_contactName`)
        4. WhatsApp profile name (`wa_name`)

      - **`{{first_name}}`**: First valid word of the consolidated name (minimum
      2 characters)


      ### WhatsApp Fields

      - **`{{wa_name}}`**: WhatsApp profile name

      - **`{{wa_contactName}}`**: Contact name as saved in WhatsApp


      ### Lead Fields

      - **`{{lead_name}}`**: Lead name

      - **`{{lead_fullName}}`**: Lead full name

      - **`{{lead_personalid}}`**: Personal ID (SSN, CPF, CNPJ, etc)

      - **`{{lead_email}}`**: Lead email

      - **`{{lead_status}}`**: Current lead status

      - **`{{lead_notes}}`**: Lead notes

      - **`{{lead_assignedAttendant_id}}`**: ID of the assigned attendant


      ### Custom Fields

      Fields added via custom fields are accessible using `{{lead_field01}}` to
      `{{lead_field20}}` or use `{{fieldname}}` defined in
      `/instance/updateFieldsMap`.


      ### Usage Example

      ```

      Hello {{name}}! I saw you work at {{company}}.

      Is your email {{lead_email}} correct?

      ```


      **💡 Tip**: Use `/chat/find` to fetch chat data and see available fields
      before sending messages with placeholders.
  - name: Async Message
    description: >
      Operational controls for the internal asynchronous send queue used when a
      send endpoint receives `async=true`.


      This section is used to:

      - check the current state of the async queue

      - configure the delay between messages sent with `async=true`

      - clear pending backlog and cancel messages not yet completed


      Scope:

      - covers only the internal queue of async direct messages

      - does not change messages already sent successfully
  - name: Message Actions and Search
  - name: Chats
  - name: Contacts
  - name: Blocklist
  - name: Labels
  - name: Groups and Communities
  - name: Newsletters and Channels
    description: >
      Operations for reading and following WhatsApp channels (newsletters).


      Main use cases:

      - list posts already published in a channel

      - edit recent posts in a channel

      - delete recent posts in a channel

      - check post views and reactions

      - integrate channels without needing to persist messages locally


      Notes:

      - `/newsletter/messages` returns the post content

      - `/newsletter/messages/edit` edits the content of recent posts

      - `/newsletter/messages/delete` deletes recent posts

      - views (`viewsCount`) and reactions (`reactionCounts`) come in each post
      of `/newsletter/messages`, not via webhook event

      - `/newsletter/updates` is deprecated: WhatsApp does not respond and the
      API returns 504

      - newsletters use their own routes and must not use `/message/edit` or
      `/message/delete`
  - name: Quick Replies
    description: >
      Management of quick replies to streamline service.


      **⚠️ Important**: This feature is only useful if you use a custom
      frontend/interface

      to register and use the replies. The API only stores the replies, 

      but does not apply them automatically.


      ### How it works:

      - **Create**: Register pre-defined responses with titles and content

      - **List**: Retrieve all registered responses to display in your interface

      - **Use**: Your frontend system can use these responses to speed up typing


      ### Use cases:

      - Custom web service interfaces

      - Mobile apps with reply suggestions

      - CRM systems with message templates

      - Productivity tools for attendants


      **Not a chatbot**: For automatic responses, use Chatbot features.
  - name: CRM

      Complete customer relationship management system integrated with the API.


      **💾 Internal Storage**: All lead data is saved directly in the API,

      eliminating the need for external databases. Your application can focus
      only

      on the interface and business logic.


      ### Available Features:

      - **📋 20+ customizable fields**: Name, phone, email, company, notes, etc.

      - **🏷️ Label System**: Organize and categorize your contacts

      - **🔍 Advanced Search**: Filter by any field or label

      - **📊 Complete History**: All interactions are registered automatically


      ### 🎯 Placeholders in messages:

      Use dynamic variables in messages for automatic personalization:


      ```

      Hello {{name}}! I saw you work at {{company}}.

      Is your email {{email}} correct?

      Notes: {{notes}}

      ```


      ### Typical Flow:

      1. **Capture**: Leads arrive via WhatsApp or forms

      2. **Enrichment**: Add data using `/chat/editLead`

      3. **Segmentation**: Organize with labels

      4. **Communication**: Send personalized messages with placeholders

      5. **Follow-up**: History is saved automatically


      **Ideal for**: Sales, marketing, support, lead qualification
  - name: Chatwoot Integration
    description: >
      **🚧 BETA INTEGRATION - Chatwoot integration system for unified service**


      **⚠️ WARNING**: This integration is in BETA phase. Use at your own risk.
      We recommend testing in a non-production environment before use in
      production.


      This category contains resources to configure and manage integration with
      Chatwoot, an open-source customer service platform. The integration allows
      centralizing WhatsApp conversations in Chatwoot.


      ### Available Features:

      - 🔧 **Complete Configuration**: Configure URL, tokens, and Chatwoot
      credentials

      - 📬 **Bidirectional Sync**: New messages between WhatsApp and Chatwoot
      are synced automatically

      - 📱 **Contact Management**: Automatic sync of names and phones

      - 🔄 **LID→PN Update**: Automatic migration from Local ID to Phone Number

      - 🏷️ **Smart Names**: Name system with tilde (~) for automatic update

      - 🚫 **Group Separation**: Option to ignore groups in sync

      - 👤 **Message Signature**: Agent identification in sent messages

      - 🔗 **Automatic Webhook**: URL generated automatically to configure in
      Chatwoot


      ### 🏷️ Smart Name System:

      - **Names with tilde (~)**: Updated automatically when contact modifies
      name in WhatsApp

      - **Specific names**: For fixed name, remove tilde (~) from name in
      Chatwoot

      - **Example**: "~John Doe" = automatic, "John Doe" = fixed

      - **LID→PN Migration**: No conversation duplication during transition

      - **Native responses**: Appear directly in Chatwoot without external
      markings


      ### ⚠️ Known Limitations:

      - **History sync**: Not implemented - only new messages are synced


      ### Use Cases:

      - Centralized service in Chatwoot

      - Support teams with multiple agents

      - CRM integration via Chatwoot

      - Communication channel centralization

      - Automatic contact and name management


      **Ideal for**: Companies with service teams, call centers, technical
      support (in test environment)


      **Requires**: Configured Chatwoot instance, API tokens, and test
      environment
