Growable One
One gateway for identity, GST, banking and vehicle verification APIs.
Growable One puts the verification and compliance APIs a business needs behind one gateway, so your developers integrate once instead of signing and wiring up a vendor for every check.

Built for the way you work
Identity and KYC checks
PAN, DigiLocker documents and OCR for Aadhaar, PAN, driving licence, passport and voter ID, returned as structured data.
GST and business verification
GSTIN lookups plus OCR for GST e-invoices and e-way bills.
Vehicle and banking
RC and FASTag lookups, bank account and IFSC services for onboarding and payouts.
Provider routing and fallback
Each API has a primary provider and an optional fallback. If one struggles, traffic can move without any change in your code.
Built for developers
Test and Live keys, a free sandbox with sample data, bearer-token auth, idempotent requests, webhooks and public docs with a live request panel.
Consent and audit controls
Consent is passed with each request, identity numbers are masked in logs, and keys support scopes, IP allowlists and team roles.
Who it is for
Fintech and lending apps, NBFCs, SaaS platforms and HR-tech teams that verify customers, businesses or documents as part of their product.

Growable One: common questions
Do I need separate vendor contracts?
No. Growable One is designed to sit in front of providers so you integrate once. Which APIs are live at a given time is shown in the catalogue on growapi.in.
What is the difference between Test and Live keys?
Test keys return synthetic sample data and are never billed. Live keys call the configured provider and are billed per the plan.
How is sensitive data handled?
Identity numbers should only be sent with the end user's consent. Sensitive fields are redacted from request logs, and access can be limited with key scopes and IP allowlists.
