Avoid this option because it increases memory usage, processing, and response size. Future versions may limit base64 for files larger than 5 MB. - **generate_mp3** (boolean, default: true): For audio, defines the return format - `true`: Returns MP3 - `false`: Returns OGG - **return_link** (boolean, kept for compatibility): The response includes the public URL of the file - **transcribe** (boolean, default: false): Transcribes audio to text - **openai_apikey** (string, optional): OpenAI key for transcription - If not provided, uses the key saved in the instance - If provided, updates and saves it in the instance for future calls - **download_quoted** (boolean, default: false): Downloads media from the quoted message - Useful for downloading original content from WhatsApp status - When a message is a reply to a status, allows downloading the media from the original status - **Contextualization**: By downloading the quoted media, you identify the context of the conversation - Example: If someone replies to a promotion, by downloading the media you will know the question is about that specific promotion ## Examples ### Download audio as MP3: ```json { "id": "7EB0F01D7244B421048F0706368376E0", "generate_mp3": true } ``` ### Transcribe audio: ```json { "id": "7EB0F01D7244B421048F0706368376E0", "transcribe": true } ``` ### Include the content in base64: ```json { "id": "7EB0F01D7244B421048F0706368376E0", "return_base64": true } ``` ### Download status media (quoted message): ```json { "id": "7EB0F01D7244B421048F0706368376E0", "download_quoted": true } ``` *Useful when the customer replies to a promotion/status - you download the original media to understand which product/offer they are asking about.* ## Response ```json { "fileURL": "https://api.exemplo.com/files/arquivo.mp3", "mimetype": "audio/mpeg", "base64Data": "UklGRkj...", "transcription": "Texto transcrito" } ``` **Note**: - By default, audio is returned as MP3 and all downloads include a public URL in `fileURL`. - Avoid `return_base64: true`: the conversion increases memory and processing usage on the server and produces a larger response. Prefer downloading the file via `fileURL`. - Future compatibility: base64 return may be limited for files larger than 5 MB. Do not rely on base64 for large files. - Transcription requires a valid OpenAI key. The key can be configured once in the instance and will be reused automatically. - Media retention: the file is available on our CDN for 2 days. After that, `fileURL` stops working. Call this endpoint again to generate a new URL, as long as the message and the original media are still available. - To keep the media for more than 2 days, download the file via `fileURL` and save it in your own storage. Storing only the URL does not extend the retention period. ## OpenAPI ````yaml /openapi-en.json post /message/download 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? ``` **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).
