Unable to Connect Vonage Phone Numbers - Application Configuration Issue

Dear VAPI Support Team,

I'm Alex from Hogarsolar,

ID: 398244ae-2f04-4764-8f10-1eec01de4284

I hope this message finds you well. I'm experiencing difficulties reconnecting our Vonage phone numbers to VAPI after accidentally deleting our Vonage application.

Issue Summary:

Previously had two Vonage numbers (34854852175 & 34854852326) working correctly with VAPI
Accidentally deleted the Vonage application from our Vonage dashboard
Created a new Vonage application with proper Voice capabilities enabled
Unable to import numbers back into VAPI - receiving "The provided credentials are not valid" error
Current Configuration:

Both numbers show "Not linked" status in Vonage dashboard
Application has Voice capabilities enabled with proper webhooks

Suggestion:
When importing your Vonage numbers into Vapi, ensure your API request or dashboard action does not include the following properties: orgIdorgId, createdAtcreatedAt, updatedAtupdatedAt, or vonageApplicationIdvonageApplicationId. These fields should be omitted from your payload, as their presence will trigger a "property ... should not exist" error.

Example (JSON payload for updating/importing a number):

{
  "apiKey": "your_vonage_api_key",
  "apiSecret": "your_vonage_api_secret",
  "applicationId": "your_vonage_application_id"
  // Do NOT include orgId, createdAt, updatedAt, vonageApplicationId
}

{
  "apiKey": "your_vonage_api_key",
  "apiSecret": "your_vonage_api_secret",
  "applicationId": "your_vonage_application_id"
  // Do NOT include orgId, createdAt, updatedAt, vonageApplicationId
}

Try removing those fields and re-importing your numbers.
See API reference for details
