Update Single Wix Collection Item Fields with an HTTP Request from Make.com, n8n or any automation platform

The problem: When using Wix Data update, you must ensure that when pushing the update, you include every field in the collection item, including the one you have updated.

UPDATE Oct 2025: WiX have released a PATCH call on the API which is now out of developer preview which aims to solve this problem.

This becomes a bit of an issue, we felt, when orchestrating changes using automation platforms for example when running complicated make.com, n8n, zapier—insert your automation tool here—scenarios.

Where we access different services and AI models to do something like the scenario below, which uses BigQuery, Openai, and Google Gemini to create a semantically relevant further reading block for your content, which is continuously updated as new content is added.

At the end of the scenario, to update just the fields you have changed, you would have to fetch all the fields in an item (adding extra complexity and maintainability issues to your scenario) and make sure you push them all into WIX.

This function simplifies all of that and lets you send only the updated fields in a JSON object like the example below at the end of a Make.com scenario:

{
    "collectionName": "yourCollectinId",
    "itemId": "itemID",
    "updates": {
        "furtherReadingBlock": "{{2.furtherReadingBlockInfoFromYourMakeScenario}}"
    }
}

This function allows external services (like Make) to securely update specific fields of a Wix collection item via an HTTP request.

It supports various field types with a simple prefixing convention to handle data safely and automatically.

A brief overview of what the code does

Authorization:

Before processing, the function checks if the request is authorised using a custom isPermitted() check. You can modify this logic to match your security model (e.g., API keys, session tokens, etc.).

Request Structure:

Endpoint:

POST /_functions/updateItemField

Content-Type:

application/json

‍

Example Payload:

{
  "collectionName": "exampleCollection",
  "itemId": "abc123",
  "updates": {
    "textField": "Updated text",
    "safebool_isPublished": "true",
    "refs_tags": ["tag1", "tag2"],
    "date_publishedAt": "2025-04-19T12:00:00.000Z"
  }
}

How to add the code to your Wix site and use it

The steps below will walk you through using a custom HTTP function on your Wix site to update specific fields in a database collection, without accidentally overwriting existing data.

This guide is beginner-friendly and requires no prior coding experience, though it helps to be familiar with your Wix site’s Content Manager and Dev Mode (Velo).

🔧 What This Does

This function lets you:

📁 Step 1: Add the Code

📝 If you already have functions in http-functions.js, just add this one at the bottom.

🔐 Step 2: Add a Secret Key

This function is secured using a key stored in Wix Secrets Manager.

1. In your site dashboard, go to Settings > Secrets Manager.
2. Add a new secret:
   • Name: my_secret
   • Value: any strong string you want to use as your key (e.g., abc123!@#)

When sending requests, include this key in the HTTP headers using either:

{
  "authorization": "abc123!@#"
}

Or

{
  "auth": "abc123!@#"
}

‍

🌐 Step 3: Understand the URL

The function is accessible via a URL like this:

https://yourdomain.com/_functions/updateItemField

Replace yourdomain.com with your actual Wix domain or custom domain.

You can use this URL in tools like Make.com, n8n, Zapier, or any service that can send POST requests.

Understanding the base URL for your use case is documented here:

https://dev.wix.com/docs/velo/velo-only-apis/wix-http-functions/wix-http-function-request/base-url

📦 Step 4: Example Request Payload

Here’s an example of how your request should look:

{
  "collectionName": "BlogPosts",
  "itemId": "1234567890abcdef",
  "updates": {
    "title": "New Blog Title",
    "date_publishDate": "2025-04-30",
    "safebool_isPublished": "true",
    "refs_categories": ["cat1", "cat2"]
  }
}

🧠 Prefix Conventions & Supported Field Types

‍

‍

Note: the field ID should match the id's in your collection item ,add the prefix to handle the field types above

What The Function Does Behind the Scenes

• Fetches the existing item
• Merges in only the updated fields
• Converts and sanitises special types
• Uses replaceReferences for reference fields
• Returns a success or error response

Limitations

• This function does not support image fields or rich text fields yet!.
• You'll need a separate function if you want to update images.

This link is publicly accessible. We have not added the code to this post because more extended code snippets are increasingly difficult to copy and paste into the code block in Wix Rich Content Editor.

📌 Tips for Using with Make.com

• Use the HTTP Module with POST method
• Set the header authorization or auth with your secret key
• Send the body in JSON format and in the example below.
