This endpoint allows you to: 1. Start voice calls to contacts 2. Works only with valid WhatsApp numbers 3. The contact will receive a voice call Without `fileUrl`, the endpoint only makes the contact's phone ring and does not establish two-way voice communication. With `fileUrl`, the API plays the file when the call is answered and ends the call when the audio finishes. MP3, WAV and OGG/Opus are accepted via HTTP(S) URL, data URI or base64, with a 25 MB limit. **Optional**: Use `call_duration` to set how many seconds the call should ring. After that period the call is ended automatically, without needing to call `/call/reject`. Use `0` to not limit audio playback by time. Request example: ```json { "number": "5511999999999", "call_duration": 0, "fileUrl": "https://exemplo.com/audio.mp3" } ``` Response example: ```json { "response": "Call request accepted locally, awaiting WhatsApp confirmation", "confirmed": false, "audio": { "requested": true, "playback": "starts_when_call_is_ready" } } ``` Common errors: - 401: Invalid or expired token - 400: Invalid or missing number - 500: Error starting call ## OpenAPI ````yaml /openapi-en.json post /call/make 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.

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? ``` **πŸ’‘ 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 description: > Complete customer relationship management system integrated with the API. **πŸ’Ύ 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: - **πŸ“‹ 20+ customizable fields**: Name, phone, email, company, notes, etc. - **🏷️ Label System**: Organize and categorize your contacts - **πŸ” Advanced Search**: Filter by any field or label - **πŸ“Š Complete History**: All interactions are registered automatically ### 🎯 Placeholders in messages: Use dynamic variables in messages for automatic personalization: ``` Hello {{name}}!
