Check the result

Read the invoice’s final sandbox outcome and handle any validation errors. You need the documentId returned by the submission request.

Request the status

Set DOCUMENT_ID to the returned tracking identifier, then run:

Read the invoice statusbash

curl "https://prod.gets.complyance.io/api/v3/documents/${DOCUMENT_ID}?type=sales" \
  --header "Authorization: Bearer ${COMPLYANCE_API_KEY}" \
  --header 'Accept: application/json'

Read data.state together with data.isTerminal. If isTerminal is false, wait before checking again and increase the delay between repeated checks. Stop polling once the response is terminal.

You should see a response like this:

Invoice accepted — HTTP 200 (shortened)json

{
  "success": true,
  "data": {
    "documentId": "01K5EXAMPLE00000000000142",
    "documentNumber": "INV-2026-0142",
    "country": "AE",
    "environment": "sandbox",
    "state": "final_valid",
    "isTerminal": true,
    "lastUpdatedAt": "2026-10-01T09:05:12.000Z",
    "errors": [],
    "validationResults": {
      "status": "Valid"
    }
  }
}

Interpret the result

State	What to do
`final_valid`	Record the successful outcome for this environment
`final_invalid` or `rejected`	Inspect the returned errors and correct the invoice
`submitted` or `processing`	Wait for the final result
`delivery_success`	Continue checking if `isTerminal` remains `false`
`delivery_failed`	Inspect the response and retain the document and request identifiers

A successful sandbox result confirms sandbox processing. It does not confirm production registration or live invoice acceptance.

If something goes wrong

A validation error names a field or rule: correct that part of the invoice and review related totals before submitting the corrected data.

The document is not found: check the returned identifier, workspace key and environment.

Processing does not finish: keep the document identifier, request identifier and latest response for support. Avoid repeatedly resubmitting the same invoice.

In the Client Portal, the same document shows in Documents with the statuses explained in Document statuses.

Next, go live to send the same invoice in production.
