I've built the basic scaffolding for a HubSpot module and successfully published a test version via railcall market publish. For the OAuth flow, the docs mention secrets never touch the DB – could you clarify the exact environment variable pattern you recommend for storing client credentials during development vs. production?

Hello Contest Holder, I have submitted my entry with a fully functional E-Commerce Landing Page demo and live URL. Please review my submission when you get a chance. Looking forward to your feedback and rating! https://zesty-chebakia-6a6fe7.netlify.app

Hello Contest Holder, I understand Round 2 requires building and publishing an original RailCall Module or Workflow that solves a real recurring business problem, with strong API coverage, secure authentication, clear documentation, and a working marketplace submission. I can handle the development, testing, documentation, publishing, and demonstration while following RailCall’s governance and quality requirements. I have a few ideas for useful integrations and workflows that I’d like to show and discuss, along with a few questions about the preferred direction. Direct discussion will help me choose and build the strongest concept for the competition. I’m waiting for your message.

Hi RailCall team, I’m preparing a Round 2 contest module and I’ve hit what appears to be a CLI installer checksum mismatch. The current railcall_cli.py served from: https://railcall.ai/cli/railcall_cli.py has SHA256: 0ea184dd37ec359008429eaaf7053fffca665bcaf3571d7799c806df97ba4278 I also verified the same CLI hash from GitHub main, the tagged release path, and the jsDelivr source. However, the published Windows install.ps1 currently expects: 27e98a518a595a9a78602c9c719ecdc20dd2bb8d75a270a5bd781535f4d27230 As a result, the official installer rejects the currently distributed RailCall CLI. I have not bypassed or modified the checksum verification. Could you please confirm whether the installer pin needs to be refreshed? My Round 2 module is otherwise ready and passes the marketplace lint with zero errors and zero warnings. I only need the Station installed so I can complete the official module signing and verification flow.

Hi RailCall team, I've published my Round 2 entry — a Stripe module (mrxstudio30/stripe), live on the marketplace and submitted here as entry #27. It covers the billing a small team actually repeats: eight commands across customers, invoices, payment links, refunds, and balance — not a one-call wrapper. The secret key stays in the vault (resolves only at 127.0.0.1, never in a receipt or the DB), it's plain Python stdlib with no dependencies, and every money-moving action is write_requires_approval, so the airlock previews and waits for approval. I ran all eight end-to-end against the live Stripe API in test mode before publishing. If there's a particular integration or capability you'd like to see expanded in Round 2, I'm glad to build on this. Thanks for running the challenge.

Hi RailCall Team, I’ve reviewed the Round 2 requirements and I’m interested in building a production ready RailCall integration around a real business use case, with meaningful action coverage rather than a basic API wrapper. My focus will be on a secure real API implementation, correct Airlock behavior for consequential actions, safe credential handling, strong error handling, signed publishing, and clear documentation that a new user can follow quickly. I can also provide a polished live demonstration showing the complete preview, approval, execution, and signed receipt flow. I’m ready to start with the current RailCall documentation and test the final module through a fresh marketplace installation before submission. Is there any integration category you would especially like to see expanded in Round 2? Best regards

Hi! Please review my entry #1. I designed this concept carefully around your brief and key requirements, with close attention to clarity, presentation, and practical use. I am happy to refine the colors, layout, typography, or other details based on your feedback. Thank you for your time!

Module or Workflow. any preference for this round, or is it fully open to us?
