Implementation Reference
- src/tools/messaging.ts:356-399 (handler)Full ToolHandler implementation for 'whatsapp_edit_message', including MCP inputSchema (JSON Schema), handler logic that validates with Zod schema, logs, calls wsapiClient.put to edit message, and returns success response.export const editMessage: ToolHandler = { name: 'whatsapp_edit_message', description: 'Edit a previously sent text message.', inputSchema: { type: 'object', properties: { messageId: { type: 'string', description: 'ID of the message to edit', }, to: { type: 'string', description: 'Chat ID where the message is located', }, text: { type: 'string', description: 'New text content for the message (max 4096 characters)', }, }, required: ['messageId', 'to', 'text'], }, handler: async (args: any) => { const input = validateInput(editMessageSchema, args); logger.info('Editing message', { messageId: input.messageId, to: input.to, textLength: input.text.length, }); const result = await wsapiClient.put(`/messages/${input.messageId}/text`, { to: input.to, text: input.text, }); logger.info('Message edited successfully', { messageId: result.id }); return { success: true, messageId: result.id, message: 'Message edited successfully', }; }, };
