POSTE-Challan Verification

Fetch pending traffic challans for any vehicle using its registration number — challan number, offence, fine amount, date, status, and issuing authority returned in a single API call.

POST/tools/kyc/touras/e-challan

Send a vehicle registration number to the E-Challan Verification API and receive a complete list of pending traffic violations from the national e-challan system (Parivahan). The response includes each challan's unique number, offence description, fine amount, date of violation, payment status, and issuing state/authority. Use it to automate fleet compliance checks, assess driver risk during onboarding, support motor insurance underwriting, or surface challan data in used-vehicle platforms.
