Retrieve Tax Invoice Issuance Deadline
Send a write date and the API returns the issuance deadline for a tax invoice with that date. You can issue up to and including the deadline. The issuance and reverse issuance request APIs also check the deadline. Call this API when you need the deadline before issuing. You need no registered issuer, certificate, or client reference ID. Test and live keys return the same result, and the call deducts no points.
The deadline is the 10th of the month after the write date. If the 10th falls on a weekend or public holiday, the deadline moves to the next business day. When the NTS extends the deadline for a month, the extended date applies. Query the deadline each time you need it. Tax invoice issuance deadline guide
