Integrating with Make

Overview

Make (formerly Integromat) lets you visually create automations across hundreds of apps. This guide shows how to call WasenderApi endpoints from Make scenarios.

Prerequisites

• Your WasenderApi base URL (e.g. https://wasenderapi.com/api)
• A Bearer Token generated in the WasenderApi dashboard
• An active WhatsApp session ID
• An active Make account

Create a Scenario to Send a Message

1. Open Make and create a new Scenario.
2. Add an HTTP > Make a request module.
3. Configure the module:
   • Method: POST
   • URL: {{BASE_URL}}/api/send-message
   • Headers
     • Authorization: Bearer <YOUR_API_KEY>
     • Content-Type: application/json
   • Body sample:

     {
       "to": "+15551234567",
       "text": "Hello from Make & WasenderApi!"
     }

4. Run the module with Run once – the response should include "success": true.
5. Continue building the scenario (triggers, routers, etc.) as needed.

For bulk sending replace to with an array (max 50, 3 on trial):

{
  "to": ["+15551234567", "+15557654321"],
  "text": "Promo message"
}

Send Media

To send an audio, video, image, document or sticker provide the corresponding URL field and omit the others:

{
  "to": "+15551234567",
  "videoUrl": "https://example.com/clip.mp4"
}

Optional: include text to add a caption for images, videos or documents.

Handling Incoming Messages

Use the Webhook module in Make:

1. Add Webhooks > Custom webhook and copy the URL generated by Make.
2. In WasenderApi, open your session → Webhooks and paste that URL.
3. Select events you care about (Message Upsert, Message Deleted, etc.).
4. Activate the scenario – Make will now receive JSON payloads for each selected event.

Tips

• Use routers to branch messages based on content (text contains, media type, etc.).
• Add filters to execute modules only for certain phone numbers or groups.
• Store data in a data store module to maintain conversation context.

Getting your API Key

1. Log in to WasenderApi.
2. Open WhatsApp Sessions, pick a session or create a new one.
3. Click Show API Key → copy.
4. In Make create an HTTP Connection credential and store:
   Authorization: Bearer YOUR_API_KEY.

Message type reference

A single request may include only one of the following media fields.

Image

{
  "to": "+15551234567",
  "imageUrl": "https://example.com/pic.jpg",
  "text": "Caption text"
}

Sticker (.webp)

{
  "to": "+15551234567",
  "stickerUrl": "https://example.com/fun.webp"
}

Poll (beta)

{
  "to": "+15551234567",
  "poll": {
    "question": "Which plan do you prefer?",
    "options": ["Basic", "Premium"],
    "multiSelect": false
  }
}

Handling errors & delays

• 401 – wrong or missing Bearer token.
• 422 – JSON body failed validation; Make shows the error object returned by WasenderApi.
• 429 – hit the rate limit; add a sleep module or Queue router.

Secure Webhooks

WasenderApi adds X-Webhook-Signature. After the custom webhook module add a Filter:

• Condition: X-Webhook-Signature equals YOUR_SECRET

Requests with mismatched signatures are dropped automatically.

Example Chatbot Scenario (Auto-Reply)

This scenario responds with the same text the user sent. You can add routers / data stores to build full decision-trees.

1. Webhooks → Custom webhook – Receive message
   • Click Add and name it whatsapp_in.
   • Copy the generated URL and paste it in WasenderApi → Session → Webhooks. Choose Message Upsert.
2. Tools → Set variable – Map reply
   • Variable name: payload
   • Value:

     {
       "to": "{{1.data.from}}",
       "text": "You said: {{1.data.text}}"
     }

     Tip: The numbers reference output bundles (1 is the Webhook module).
3. HTTP → Make a request – Send reply
   • Method: POST
   • URL: {{BASE_URL}}/api/send-message
   • Headers:
     • Authorization: Bearer {{YOUR_API_KEY}}
     • Content-Type: application/json
   • Body type: Raw → JSON (application/json)
   • Request content: {{2.payload}}
4. Toggle Scheduling On and click Run once to test. Send a WhatsApp message and observe the bundles flowing.

Add Router + Filter branches to build menus. Add HTTP calls to an AI endpoint for smart replies. Your imagination is the limit.
