Webhook Handling

Quick Start

Parse Any Webhook

Use the unified schema to automatically validate and parse any webhook:

import { WhatsAppWebhookSchema } from 'whatsapp-cloud-api-types'

// In your webhook endpoint (Express example)
app.post('/webhook', (req, res) => {
  try {
    const webhook = WhatsAppWebhookSchema.parse(req.body)

    // TypeScript knows the structure
    webhook.entry.forEach(entry => {
      entry.changes.forEach(change => {
        if (change.field === 'messages') {
          // Handle incoming messages
          const messages = change.value.messages
          const statuses = change.value.statuses
        }
      })
    })

    res.sendStatus(200)
  } catch (error) {
    console.error('Invalid webhook payload:', error)
    res.sendStatus(400)
  }
})

Parse Specific Webhook Types

For better type inference, use specific webhook schemas:

Messages Webhook

import { MessagesWebhookSchema } from 'whatsapp-cloud-api-types'

const webhook = MessagesWebhookSchema.parse(req.body)

webhook.entry.forEach(entry => {
  entry.changes.forEach(change => {
    // Handle incoming messages
    change.value.messages?.forEach(message => {
      console.log(`Message from ${message.from}: ${message.text?.body}`)

      // Type-safe access to different message types
      switch (message.type) {
        case 'text':
          console.log('Text:', message.text?.body)
          break
        case 'image':
          console.log('Image ID:', message.image?.id)
          break
        case 'interactive':
          console.log('Button clicked:', message.interactive?.button_reply?.title)
          break
      }
    })

    // Handle message status updates
    change.value.statuses?.forEach(status => {
      console.log(`Message ${status.id} is now ${status.status}`)
    })
  })
})

Template Status Update Webhook

import { MessageTemplateStatusUpdateWebhookSchema } from 'whatsapp-cloud-api-types'

const webhook = MessageTemplateStatusUpdateWebhookSchema.parse(req.body)

webhook.entry.forEach(entry => {
  entry.changes.forEach(change => {
    const { event, message_template_name, reason } = change.value

    switch (event) {
      case 'APPROVED':
        console.log(`Template ${message_template_name} was approved!`)
        break
      case 'REJECTED':
        console.log(`Template ${message_template_name} was rejected. Reason: ${reason}`)
        break
      case 'DISABLED':
        console.log(`Template ${message_template_name} was disabled`)
        if (change.value.disable_info) {
          console.log(`Disabled on: ${new Date(change.value.disable_info.disable_date * 1000)}`)
        }
        break
    }
  })
})

Template Quality Update Webhook

import { MessageTemplateQualityUpdateWebhookSchema } from 'whatsapp-cloud-api-types'

const webhook = MessageTemplateQualityUpdateWebhookSchema.parse(req.body)

webhook.entry.forEach(entry => {
  entry.changes.forEach(change => {
    const { message_template_name, previous_quality_score, new_quality_score } = change.value

    console.log(`Template "${message_template_name}" quality changed from ${previous_quality_score} to ${new_quality_score}`)

    if (new_quality_score === 'RED') {
      console.warn('⚠️ Template quality is now RED! Consider reviewing your template.')
    }
  })
})

Template Components Update Webhook

import { MessageTemplateComponentsUpdateWebhookSchema } from 'whatsapp-cloud-api-types'

const webhook = MessageTemplateComponentsUpdateWebhookSchema.parse(req.body)

webhook.entry.forEach(entry => {
  entry.changes.forEach(change => {
    const template = change.value

    console.log(`Template "${template.message_template_name}" was updated`)
    console.log('Body:', template.message_template_element)

    if (template.message_template_title) {
      console.log('Header:', template.message_template_title)
    }

    if (template.message_template_buttons) {
      console.log('Buttons:', template.message_template_buttons.map(b => b.message_template_button_text))
    }
  })
})

Template Category Update Webhook

import { TemplateCategoryUpdateWebhookSchema } from 'whatsapp-cloud-api-types'

const webhook = TemplateCategoryUpdateWebhookSchema.parse(req.body)

webhook.entry.forEach(entry => {
  entry.changes.forEach(change => {
    const value = change.value

    // Check if it's an impending change notification
    if ('correct_category' in value) {
      console.log(`Template "${value.message_template_name}" will be recategorized from ${value.new_category} to ${value.correct_category} in 24 hours`)
    } else {
      console.log(`Template "${value.message_template_name}" was recategorized from ${value.previous_category} to ${value.new_category}`)
    }
  })
})

Advanced Usage

Type Guards

Use Zod's safeParse for safe validation:

import { WhatsAppWebhookSchema } from 'whatsapp-cloud-api-types'

app.post('/webhook', (req, res) => {
  const result = WhatsAppWebhookSchema.safeParse(req.body)

  if (!result.success) {
    console.error('Validation failed:', result.error.issues)
    return res.sendStatus(400)
  }

  const webhook = result.data
  // Process webhook...

  res.sendStatus(200)
})

Discriminated Union

Use TypeScript's discriminated unions to handle different webhook types:

import { WhatsAppWebhook } from 'whatsapp-cloud-api-types'

function handleWebhook(webhook: WhatsAppWebhook) {
  const change = webhook.entry[0].changes[0]

  switch (change.field) {
    case 'messages':
      handleMessages(change.value)
      break
    case 'message_template_status_update':
      handleTemplateStatusUpdate(change.value)
      break
    case 'template_category_update':
      handleTemplateCategoryUpdate(change.value)
      break
    // TypeScript ensures you handle all cases
  }
}

Extract Specific Types

import type {
  Message,
  Status,
  TemplateStatusEvent,
  TemplateQualityScore
} from 'whatsapp-cloud-api-types'

function processMessage(message: Message) {
  if (message.type === 'text') {
    return message.text?.body
  }
  // TypeScript knows the structure
}

function checkQuality(score: TemplateQualityScore) {
  return score === 'GREEN' || score === 'YELLOW'
}

Subscription Management

Subscribe to a WABA

import { SubscribeToWABAResponseSchema } from 'whatsapp-cloud-api-types'

const response = await fetch(
  `https://graph.facebook.com/v18.0/${wabaId}/subscribed_apps`,
  {
    method: 'POST',
    headers: { Authorization: `Bearer ${accessToken}` }
  }
)

const result = SubscribeToWABAResponseSchema.parse(await response.json())
console.log('Subscribed:', result.success)

Get All Subscriptions

import { GetSubscriptionsResponseSchema } from 'whatsapp-cloud-api-types'

const response = await fetch(
  `https://graph.facebook.com/v18.0/${wabaId}/subscribed_apps`,
  {
    method: 'GET',
    headers: { Authorization: `Bearer ${accessToken}` }
  }
)

const result = GetSubscriptionsResponseSchema.parse(await response.json())
result.data.forEach(app => {
  console.log(`App: ${app.whatsapp_business_api_data.name}`)
})

Override Callback URL

import {
  OverrideCallbackURLRequestSchema,
  OverrideCallbackURLResponseSchema
} from 'whatsapp-cloud-api-types'

const requestBody = OverrideCallbackURLRequestSchema.parse({
  override_callback_uri: 'https://your-webhook.com/endpoint',
  verify_token: 'your-verify-token'
})

const response = await fetch(
  `https://graph.facebook.com/v18.0/${wabaId}/subscribed_apps`,
  {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${accessToken}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(requestBody)
  }
)

const result = OverrideCallbackURLResponseSchema.parse(await response.json())
console.log('Override successful:', result.data[0].override_callback_uri)

Unsubscribe from WABA

import { UnsubscribeFromWABAResponseSchema } from 'whatsapp-cloud-api-types'

const response = await fetch(
  `https://graph.facebook.com/v18.0/${wabaId}/subscribed_apps`,
  {
    method: 'DELETE',
    headers: { Authorization: `Bearer ${accessToken}` }
  }
)

const result = UnsubscribeFromWABAResponseSchema.parse(await response.json())
