Finding Your Omada Customer ID (omadac_id)

The Problem

If you're seeing this error:

Omada login failed: Controller ID not exist.

It means you're using the wrong value for omadac_id in the login request.

The Solution

You need to find the correct Customer/Controller ID from your Omada OpenAPI settings.

Step-by-Step Instructions

Log into your Omada Cloud Controller (using the same region as your URL, e.g., euw1)
Navigate to OpenAPI Settings:
- Go to Settings → Platform Integration → Open API
- Or: Global View → Settings → Platform Integration → Open API
Find Your Application:
- Look for your application in the list (the one with your TP_LINK_CLIENT_ID)
- Click View or Details on that application
Find the Customer/Controller ID:
- On the details screen, you should see:
  - Client ID (this is your TP_LINK_CLIENT_ID)
  - Client Secret (this is your TP_LINK_CLIENT_SECRET)
  - Customer ID or MSP ID or Controller ID or Omada ID / OmadacId
    - ⚠️ This is the value you need!

Update Your .env File:

# Use the Customer/Controller ID from step 4
OMADA_CUSTOMER_ID=the-exact-value-from-openapi-settings

# Or for backward compatibility:
OMADA_ID=the-exact-value-from-openapi-settings

Restart Your Application:
```
pnpm run dev
```

Important Notes

The OMADA_CUSTOMER_ID is different from your TP_LINK_CLIENT_ID
The OMADA_CUSTOMER_ID is the ID of your controller/customer, not your application
This value is used as the omadac_id query parameter in the login request
If you're using an MSP (Managed Service Provider) account, you might see "MSP ID" instead

Verification

After updating, you should see:

✅ Login succeeds, OR
✅ A different error like "invalid username/password" (which means the ID is correct!)

If you still see "Controller ID not exist", double-check that you copied the exact value from the OpenAPI settings page.
