Enhanced KYC_CKYC_BULK_SEARCH API (POST /v2/kyc/ckyc/bulk/search) and KYC_CKYC_BULK_DOWNLOAD API (POST /v2/kyc/ckyc/bulk/download) with asynchronous processing:

IV. JWT Token Authentication Support for v2 APIs

  • Introduced a new authentication mechanism via the /v2/auth/token endpoint.
  • Clients can now generate short-lived JWT tokens using existing client credentials.
  • Offers a secure, modern alternative to traditional client_id / client_secret auth for Fabric v2 APIs.

V. Enhanced Reliability for MCA APIs with Parallel Retry Mechanism

  • Implemented a parallel thread-based retry mechanism for MCA APIs.
  • Improves CIN retrieval speed and reliability for GSTIN_DETAILED document types.
  • Uses multiple concurrent attempts for better consistency and reduced latency.
