data.balance
Returned wallet balance string.
Vehicle lookup capability
FASTag Balance API
Review returned FASTag wallet balance, usable balance, balance availability and update timestamp by vehicle number.
Using fastag balance in your workflow
Use the balance fields already documented by the India FASTag & Vehicle Owner API. Review wallet and usable balance separately, check whether balance information is available, and keep the update timestamp visible. This is a balance-focused view of the existing FASTag lookup, not a field in the RC Vehicle Info response.
- 1Submit the vehicle number to the existing FASTag endpoint.
- 2Check balance_status before interpreting the balance values.
- 3Show wallet balance and usable balance separately.
- 4Display balance_updated_at so users can assess freshness.
