To create a data layer variable in Google Tag Manager with Claude or ChatGPT, connect your Google Tag Manager account to PaidSync.ai and ask the assistant to create a data layer variable, which makes a value available to tags and triggers. It changes the workspace, so read the request before you approve.

Which Tools Do the Work

Your site may push values, such as an order total, to the data layer. A write tool creates the variable that reads one:

list_gtm_variables lists the variables you already have.
create_gtm_variable creates a user defined variable such as a data layer variable, with a name and parameters.

list_gtm_variables only reads your account. create_gtm_variable changes it. That is the full set you need to create a data layer variable.

How the Workflow Is Built

Tool	What it does
list_gtm_variables	Checks existing variables
create_gtm_variable	Creates the variable

Use the exact key your site pushes. A typo returns empty values and the tag quietly sends nothing.

How to Create a Data Layer Variable in Google Tag Manager With Claude in 5 Steps

These steps use Claude to create a data layer variable. PaidSync.ai also works in ChatGPT, and the prompts are the same.

Connect Google Tag Manager to PaidSync.ai

Register at paidsync.ai and connect Google Tag Manager with Google's own sign-in screen. It needs no API key and no config file. Pick the Google login that manages the container you will create a data layer variable in.

Add PaidSync.ai to Claude

Add PaidSync.ai from Claude's connector directory and sign in. Ask "list my Google Tag Manager containers" and choose the one to create a data layer variable in.

Check existing variables

List the variables.

Define the new one

Give the name and the data layer key.

Create and read back

Approve it and list the variables again.

How to Check the Result

Use preview mode on the site and confirm the variable holds a value.

Use these two prompts to create a data layer variable, in this order.

"List the user defined variables in my workspace."

Reads your account and changes nothing.

"Create a data layer variable named DLV order total that reads the key ecommerce.value."

Applies when your assistant runs it, so approve it only after you read it.

How PaidSync.ai Protects You

Reads change nothing. list_gtm_variables only reads Google Tag Manager, so the lookup before you create a data layer variable changes nothing.
No preview, so keep approvals on. create_gtm_variable applies on the first call without a dry run, so when you create a data layer variable, your assistant's approval prompt is the check before it runs.
Approval before each change. From Claude or ChatGPT, your assistant's own approval setting decides whether it asks before create_gtm_variable runs to create a data layer variable.
Your own sign-in. The tools that create a data layer variable reach Google Tag Manager only through the access you approve on Google's own screen. Tokens are encrypted at rest, and you can remove access at any time from your Google Account.

Every Google Tag Manager tool PaidSync.ai offers is listed on the Google Tag Manager MCP server tools page, including the tools used to create a data layer variable.
