How a GSP differs from an ASP is explained on the GSP APIs page.

The APIs take the same JSON from any system, so the work is in where your invoice or dispatch document lives.

Frequently Asked Questions
Something not covered here?
Ask us directly.GST API integration connects your ERP, accounting software or practice tool directly to the GST system through a GST Suvidha Provider (GSP). Your software can then file returns, generate e-Invoice IRNs, create e-Way Bills and verify GSTINs without anyone logging in to the portal manually.
Request access on the page. Figment's API team confirms your use case and emails sandbox credentials with test GSTINs, sample payloads, the Postman collection and documentation.
Yes. The sandbox is separate from your live setup, so you can run the same invoices through both and compare. When you are ready, you can switch all APIs, switch a few, or keep Figment as a standby provider.
Share the APIs you use and some sample requests and responses. Figment's API team maps your fields, authentication and error codes to Figment's APIs, supports side-by-side testing and cuts over between filing windows.
Company verification (KYC), a signed agreement and production keys from Figment, typically within two weeks of sandbox access. For return-filing APIs, each taxpayer also enables API access on the GST portal and authorises it with an OTP.
The APIs are REST/JSON, so they work with SAP, Oracle, Microsoft Dynamics, Tally and in-house systems. A Postman collection and documentation come with the sandbox, and Figment's API team helps with the integration.
Yes. Figment is a GSTN-authorised GST Suvidha Provider, so requests go through Figment's own authorised channel to GSTN, the e-Invoice IRPs and NIC, with redundant links and automatic failover.
