Generates a VAT return report as a report job
NewReports

POST /reports/jobs accepts reportType VAT_REPORT with reportArgs.filingId, for a VAT filing in Germany, the United Kingdom, the Czech Republic, Spain or Singapore. Once the job is READY, GET /reports/jobs/{report_job_id}/result returns it as JSON in vatReport: the return form's boxes grouped in sections, each with its boxCode, boxLabel, amount, category and sourceTransactionCount; a summary of output VAT, input VAT, net VAT payable and sales and purchases excluding VAT; ossDestinations, the VAT owed per EU destination country, or null when there are no cross-border sales; and limitations. Amounts are decimal strings rounded to the cent. Creating the job answers 404 for a filing outside the organization, 400 for another country, for a filing with more than 100,000 transactions or with deliveryMethod EMAIL, and 403 for an organization without this feature enabled. The result endpoint answers 400 for a report you download instead, 409 before the job is READY and 404 for a job you cannot access.

What to do
  • Start the job, poll GET /reports/jobs/{reportJobId} until it is READY, then read the report from the result endpoint.

Emails a report's download link on request
NewReports

POST /reports/jobs accepts an optional deliveryMethod. DOWNLOAD, the default, works as before: fetch the report from GET /reports/jobs/{reportJobId}/download once it is READY. EMAIL sends a download link, when the report is ready, to the email address of the user behind your credential; the request cannot name another address. The response echoes deliveryMethod. EMAIL answers 400 for BULK_FILING_REPORTS, for an organization with email turned off, and for a credential without an email address.

What to do
  • Send deliveryMethod: "EMAIL" to receive the report link by email.
