Designed for finance-critical traffic
The platform is tuned for document generation, transport compliance, GST data retrieval, and the operational edge cases that come with them.
Secure by Default
Authentication, encrypted transport, and controlled access are built into every integration path from sandbox to production.
Traffic-Ready Architecture
Designed for high-volume document and transport workflows, including busy filing periods and rollout-heavy business hours.
Schema-Aware Validation
Workflows are aligned to the document and data structures teams expect when building GST, IRN, and e-Waybill flows.
Seamless Integration
The platform is shaped for ERP, billing, workflow, and product teams that need clean request and response patterns.
Retry-Safe Processing
Queue-backed processing, retry handling, and clear operational behavior reduce friction when workflows fail or need replay.
Operational Visibility
Teams get the context they need for monitoring, troubleshooting, and keeping compliance-heavy workflows understandable.
See the request shape before you build
Use sandbox examples to understand how authentication, payloads, and structured responses fit into your app before you wire production traffic.
HTTP-first examples
Simple request patterns that teams can adapt quickly
Structured JSON
Readable fields that fit cleanly into ERP and app workflows
Sandbox-safe testing
Validate payloads and handling logic before go-live
curl -X POST https://staging.perione.in/v1/einvoice/generate \
-H "Authorization: Bearer YOUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{

The onboarding path is designed to help technical teams validate fast, then move to production with fewer surprises.
Request Sandbox Access
Start with a sandbox account so your team can validate request shapes, auth flow, and workflow coverage.
- No credit card for evaluation
- Environment-ready access
- Docs available from day one
Authenticate and Map Flows
Connect authentication once, then map e-Invoice, e-Waybill, and GST data workflows into your product or ERP.
- Bearer token flow
- Structured payload patterns
- Implementation guidance
Promote to Production
Move the validated flow into production with the right credentials, monitoring, and operational support model.
- Production onboarding
- Operational readiness
- Go-live support
Built for rollout-heavy teams
The platform fits teams that need compliance workflows to be reliable, understandable, and fast to integrate.
ERP and SI Partners
Teams embedding GST, e-Invoice, and e-Waybill workflows into ERP rollouts and customer delivery projects.
Finance Platforms
Products that need tax and compliance workflows without building a large internal compliance integration layer.
B2B SaaS Teams
Software teams that need clear auth, payload, and response patterns they can ship confidently into production.
Logistics Operations
Dispatch and transport teams that need cleaner e-Waybill handling, vehicle updates, and workflow visibility.
Enterprise-Grade controls
Compliance workflows need more than nice APIs. They need secure transport, predictable processing, and implementation discipline.
Schema-Aligned Workflows
Document and data flows are designed around the structures teams expect for GST, IRN, and transport operations.
Encrypted Transport
Secure transport and controlled credential handling help teams reduce risk across sandbox and production environments.
Resilient Delivery
The platform is built for continuity, observability, and predictable behavior when workflows need retries or close review.
Everything You Need to ship reliably
The platform is shaped for teams that care about integration speed, operational clarity, and dependable rollout behavior.

A single authentication pattern helps teams standardize access across multiple compliance workflows.
Retry-Aware Processing
Operational safeguards and replay-friendly behavior reduce friction when requests fail or need inspection.
Implementation Guides
Clear docs, examples, and workflow context help teams move from evaluation to rollout faster.
Production Support Options
Support can be aligned to rollout stage, operational criticality, and the people running the integration.
Operational Monitoring
Health checks and operational visibility help teams understand how the integration is behaving in real time.
Structured Output
Consistent response shapes make it easier to map data into ERP, app, and reporting workflows.
Audit-Friendly Visibility
Teams can review workflow behavior, trace issues, and keep compliance operations easier to reason about.
Validation Controls
Request validation and workflow guardrails help catch problems before they create downstream operational noise.
GST API pricing India that starts in sandbox. Production when ready
Validate the integration in sandbox first, then move to a production plan sized to your volume, workflow complexity, and support needs.
