Important Update: Deprecated GST API Authentication mechanism

[Chartered Information Systems Pvt. Ltd.]

Dear ASPs,

We hope this message finds you well. We would like to inform you about a new and important update regarding the authentication mechanism for our GST Public API, which we had release on 1st of March 2025.

We have mapped https://deprecatedgstapi.charteredinfo.com to the old version of our GSP API. This domain will remain available for the medium term, approximately a couple of years. During this period, ASPs using the old technology stack will still be able to utilize the previous authentication method.

As part of our ongoing efforts to improve our services and align with industry standards, we encourage all ASPs to consider upgrading to the new Authentication mechanism at your earliest convenience. This transition will ensure smoother operations and enhanced security measures.

Should you have any questions or require assistance with the transition, please do not hesitate to reach out to our support team at g...@taxpro.co.in.

Thank you for your continued partnership.

Thanks & Regards,

TaxPro GSP.
