I need a compact TDL add-on built for Tally that focuses purely on licensing and validation. The add-on must talk to our own software, exchange keys, and keep subscription status in sync every time Tally starts or a licence-related action is triggered. Core features to code: • Robust licence-key validation that blocks access when the key is expired or invalid. • Background subscription checks that update remaining days and renewal status without slowing Tally. You will have direct API access to our server; the payloads are simple JSON over HTTP. I’ll share the endpoint specs, sample keys and expected response codes as soon as we start. Because quick iterations and an occasional in-person discussion help, I’m looking specifically for someone based in Chennai or elsewhere in Tamil Nadu. If you already work with Tally Developer, know how to call external REST services from TDL, and can package the final TCP with clear setup instructions, this should be straightforward. Deliverable: 1. TDL source & compiled TCP ready to deploy 2. A short, step-by-step document covering installation, key activation, renewal flow and error handling I’ll test by activating a trial key, forcing an expiry, and confirming the add-on locks and unlocks exactly as intended. Once those checks pass, we’re done.

Hi, I've reviewed your requirements and can develop a secure TDL add-on for Tally that handles license validation and subscription management through your REST APIs. The add-on will validate license keys, synchronize subscription status with your server, update remaining validity automatically, and restrict access whenever a license is invalid or expired. The API communication will be designed with proper error handling, secure key exchange, and minimal impact on Tally's startup performance. You'll receive the complete TDL source code, compiled TCP, and clear documentation covering installation, license activation, renewal flow, and troubleshooting. The solution will be modular, making it easy to maintain and extend as your licensing requirements evolve. I'm ready to review your API specifications and begin implementation as soon as they're available. Looking forward to working with you. Best regards, Vandini

Could you provide more details about the specific licensing logic you need? Are there any additional requirements for syncing with your software? I have experience working with TDL and integrating REST APIs. I can create a compact TDL add-on that features robust license-key validation and performs background checks for subscription status effectively. This will ensure Tally runs smoothly without any interruptions due to licensing issues. Being in Tamil Nadu, I’m available for quick iterations and discussions as needed. I’ll also ensure that the final TCP is packaged with clear setup instructions for easy deployment.

Hi, I can develop a secure TDL add on for Tally that handles license validation, subscription management, and seamless REST API integration with your licensing server. Here's my approach: → Implement robust license key validation with automatic access control for expired or invalid licenses. → Integrate REST APIs using JSON over HTTP for real-time subscription checks and license synchronization. → Package the solution as deployable TDL source and TCP with clear installation, activation, renewal, and error-handling documentation. → Ensure lightweight background validation with minimal impact on Tally's startup performance. Flow: Tally Startup → License Validation → API Authentication → Subscription Sync → Access Control → Renewal & Status Updates Let's connect Thanks.
