Automate GlobalConnect with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• CX Connect cases with a new collaboration

  Build this

  Starts

  Every weekday at 7:00

  Step 1

  List the open cases in the Dealer Cases list view in CX Connect.

  Step 2

  For each case, read its collaborations.

  Step 3

  Keep the cases whose latest collaboration changed since the last run.

  Step 4

  Email you each one with its case number, support area, VIN and the new collaboration text.

• Warranty block check for tomorrow's service appointments

  Build this

  Starts

  When your system calls the workflow's webhook with a list of VINs

  Step 1

  For each VIN, check Investigate Vehicle History for warranty blocks.

  Step 2

  Keep the vehicles that have a block.

  Step 3

  Post each one, with its block reason, to your DMS or Slack webhook.

• Weekly open-case summary for the service manager

  Build this

  Starts

  Every Monday at 8:00

  Step 1

  List the open cases in the Dealer Cases list view in CX Connect.

  Step 2

  Group them by support area, TAC or TCSC, with an AI step.

  Step 3

  Email you the summary with case numbers, VINs and latest collaborations.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “List open CX Connect cases” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "gmglobalconnect.com/list_open_cx_connect_cases",
    "input": {
      "support_area": "TAC"
    }
  }'

{
  "status": "completed",
  "data": {
    "cases": [
      {
        "case_number": "00731482",
        "support_area": "TAC",
        "vin": "1GNSKRKD5PR104417",
        "latest_collaboration": "Please perform the pinpoint test in step 4 and attach the session log."
      },
      {
        "case_number": "00729915",
        "support_area": "TAC",
        "vin": "1GTUUDED1RZ238806",
        "latest_collaboration": "Bulletin procedure confirmed. Replace the module and reprogram."
      }
    ],
    "count": 2
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

GlobalConnect’s own options

We found no API that GM offers dealership users for GlobalConnect. Retail deliveries, financial statements, warranty claims and parts orders reach GM through the GM integrations built into dealer management systems such as CDK's. Cases, vehicle history and inspection forms are handled in the applications GlobalConnect launches from its App Center.

Read on November 12, 2026: CDK Global: GM integrations, GM TechLink: Find the Training Times Newsletter on GlobalConnect, GM TechLink: PDI forms on the GlobalConnect App Center.

Signing in to GlobalConnect

GlobalConnect signs you in through GM's Microsoft Azure sign-in: your GlobalConnect ID followed by @vsp.autopartners.net, and your GlobalConnect password. GM's Azure roadmap lists multifactor authentication and sign-in with a dealership ID for dealerships that run their own Azure. With Fous you sign in once through that sign-in with your own account. The login is sealed with AES-256.

Worth knowing

Your ID now ends in @vsp.autopartners.net

GM moved GlobalConnect's sign-in to Microsoft Azure. The Azure ID is your GlobalConnect ID with @vsp.autopartners.net added, and the password stays the same.

Phone support needs a CX Connect case number

Since August 26, 2026, TAC and TCSC ask for a CX Connect case number before phone support. CX Connect is U.S. only and opens from the App Center.

Use Dealer Cases if My Open Cases is empty

After the July 2026 CX Connect release, some users could not see their cases in the My Open Cases list view. GM's workaround is the Dealer Cases list view, sorted by Contact Name.

Warranty blocks show in IVH

GM says to check Investigate Vehicle History for warranty blocks, for example after a salvage title. On a blocked vehicle, TCSC supports only recalls, special coverage and emissions warranty issues.
