ChargeIndia Hub is built for the Indian EV charging market. Follow these conventions when integrating.
Country and currency
| Field | Convention |
|---|---|
country_code | IN for Indian parties |
| Currency | INR (Indian Rupee) in tariffs and CDRs |
| Timestamps | Stored and transmitted in UTC (ISO 8601) |
Display times to end users in IST (UTC+5:30) on your platform — the Hub stores UTC.
Party identifiers
Indian parties use:
country_code: 2-character ISO code (IN)party_id: 3-character identifier assigned during onboarding (e.g.ABC)
Hub identity: IN / CIH.
GSTIN metadata
Partners may include GSTIN (GST Identification Number) in business_details during credentials exchange. The Hub stores this metadata but does not:
- Validate GSTIN with government APIs
- Generate tax invoices
- Calculate or remit GST
GST invoicing is handled bilaterally between eMSP and CPO outside the Hub.
Pricing
- Tariffs should use INR with appropriate
price_components - The Hub passes tariffs through for authorization pricing context only
- Payment collection is out of scope for Phase 1
UPI prepaid flows and payment authorization gates are planned for a future phase. Phase 1 delivers technical roaming only.
What the Hub does not do
| Capability | Status |
|---|---|
| UPI / wallet payments | Phase 2+ |
| GST invoice generation | Never — Hub orchestrates data only |
| Escrow / settlement | Out of scope |
| Hub commercial billing | Phase 4+ |
