Connect Pabbly Connect to WhatsApp

Pabbly Connect's defining feature is flat pricing with unlimited tasks and free internal apps. Use API by Pabbly to call WA.Expert and send WhatsApp messages from any workflow: filters and routers do not count against your task limit, and lifetime deals are available.

Internal apps are free in Pabbly: filters and routers do not count as tasks

This is Pabbly's standout advantage. Filters, path routers, text and number formatters, date formatters, iterators, and schedulers do not count as tasks. Only the trigger and external action steps consume tasks. You can build complex multi-step logic without inflating your task usage, unlike Zapier and Make.

Pabbly uses API by Pabbly to call WA.Expert: no native app

There is no dedicated WA.Expert app in Pabbly Connect. Use the API by Pabbly action module to send an HTTP request to the WA.Expert API. This is available on all Pabbly plans including the free tier.

Endpoint URL: https://api.wa.expert/v1/send

Headers:
  API-KEY: YOUR_WAEXPERT_API_KEY
  Content-Type: application/json

Payload Type: JSON

Body:
{{
  "to":       "[phone from trigger]",
  "type":     "template",
  "template": {{
    "name":     "order_confirmation",
    "language": {{"code": "en"}},
    "components": [
      {{
        "type": "body",
        "parameters": [
          {{"type": "text", "text": "[name from trigger]"}},
          {{"type": "text", "text": "[order_id from trigger]"}}
        ]
      }}
    ]
  }}
}}

Map [phone from trigger] etc. by clicking the field and selecting
the mapped value from the trigger step's data.
Map trigger data with Pabbly's field selector

In the API by Pabbly body, click into any value field and Pabbly shows a dropdown of all fields captured from the trigger step. Select the phone number field for the to value and the relevant fields for each template variable. Pabbly inserts the mapping automatically.

Step 3: Test and enable

1
Click Save & Send Test Request on the API by Pabbly step.
2
Check the response shows a success status. Verify the WhatsApp arrived and check WA.Expert's message logs.
3
The workflow runs automatically. Pabbly polls or listens for the trigger depending on the app.

Direction 2: WhatsApp data triggers a Pabbly workflow

Receive WhatsApp reply data from WA.Expert into Pabbly to update a CRM, add a row to Google Sheets, or trigger any downstream action.

1
In Pabbly Connect, create a new workflow. For the trigger, choose Webhook by Pabbly. Copy the webhook URL.
2
In WA.Expert, add an External API Request step. POST the customer data to the Pabbly webhook URL.
3
In Pabbly, click Recapture Webhook Response and trigger the WA.Expert automation to send a test payload.
4
Add action steps after the webhook: Google Sheets, HubSpot, a filter, a router, etc. Filters and routers do not count as tasks.
WA.Expert External API Request — POST to Pabbly webhook
POST https://connect.pabbly.com/workflow/sendwebhookdata/YOUR_HOOK_ID
Content-Type: application/json

Body:
{{
  "customer_name":    "{{customer_name}}",
  "customer_phone":   "{{customer_phone}}",
  "customer_message": "{{customer_message}}"
}}

Pabbly receives this and routes through the workflow:
  Webhook -> Filter (free) -> Google Sheets (counts as task)
                           -> Router (free) -> HubSpot (counts as task)

Worked example: lead form to WhatsApp with routing

Pabbly workflow — Facebook Lead to WhatsApp with conditional routing
1. Trigger: Facebook Lead Ads — New Lead (1 task)
   Captured: name, phone, city, budget

2. Filter: only continue if budget > 50000 (FREE — no task)

3. Router: split by city (FREE — no task)
   Route A (Mumbai) -> API by Pabbly -> WA.Expert (1 task)
     Template: mumbai_welcome
   Route B (other)  -> API by Pabbly -> WA.Expert (1 task)
     Template: general_welcome

4. API by Pabbly -> WA.Expert send:
   POST https://api.wa.expert/v1/send
   Header: API-KEY: YOUR_KEY
   Body: {{to: [phone], template: {{name: 'mumbai_welcome', ...}}}}

Total tasks used per qualifying lead: 2 (trigger + 1 send)
Filter and router: free. Complex logic at no extra task cost.

Troubleshooting

API by Pabbly returns errorWrong URL or API-KEY headerConfirm the endpoint is https://api.wa.expert/v1/send. Add API-KEY as a header (not Authorization). Check the key value.

Phone number not mappedMapping not selectedClick the 'to' field and select the phone number value from the trigger step's dropdown. Ensure it includes the country code (+91).
Webhook not capturing dataWrong webhook URL in WA.ExpertCopy the full Pabbly webhook URL and paste it exactly into the WA.Expert External API Request step. Click Recapture in Pabbly to test.
Hitting task limit unexpectedlyExternal actions countingOnly trigger and external actions count. If you are near the limit, check whether you have multiple external action steps that could be combined.
Workflow not triggeringTrigger app polling intervalSome Pabbly triggers poll on an interval rather than instantly. Check the trigger app's documentation for the polling frequency.
