Return Invoice PDF URL

GET /v3/Invoices/{InvoiceKey} now returns InvoicePdfUrl, a link to the rendered invoice PDF. Use it to preview the invoice, download it, or pass it on to your client.

GET /v3/Invoices/{InvoiceKey}

{
  // ...existing invoice fields
  "InvoiceKey": "M2dVbCt4RHk",
  "InvoiceNumber": "KIN-1001",
  "InvoiceStatus": "AwaitingPayment",
  "InvoicePdfUrl": "/v3/Files?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9..."
}

InvoicePdfUrl is only returned once the invoice has been posted or sent; otherwise it’s null. This field is not returned on the /v3/Invoices list endpoint.

The URL includes a token that is valid for 15 minutes — the same format GET /v3/FileDetails/{key} returns — so request the invoice again for a fresh link rather than storing it.

Estimated Amount on Estimate Summaries

GET /v3/EstimateSummaries/{WorkItemKey} now returns EstimateAmount on each summary — the estimated cost of the work, calculated from EstimateMinutes at the user’s HourlyRate. Previously you had to work this out yourself.

GET /v3/EstimateSummaries/4jgPTtcXxwC2

{
  "value": [
    {
      // ...existing estimate summary fields
      "EstimateSummaryKey": "160F79F6-E650-40C3-8BD9-F70C287B7476-0",
      "TaskTypeName": "Admin",
      "EstimateMinutes": 60,
      "HourlyRate": 150,
      "ActualMinutes": 45,
      "EstimateAmount": 150
    }
  ]
}

Estimate summaries remain read-only — EstimateAmount is calculated by Karbon and can’t be set through the API.
