CONTEST: Build a RailCall module or workflow - $2,500 USD prize pool RailCall is a governance-first automation layer for AI-driven work - every action a workflow takes goes through a preview -> approve -> execute -> signed receipt loop (the "airlock"), so operators and enterprises can trust what the automation is doing. We're opening the platform to the community. Build a MODULE (a new integration - Slack, HubSpot, Airtable, Zendesk, whatever) or a WORKFLOW (a real end-to-end automation on top of what's already there), publish it to the marketplace, and win a share of the pool. PRIZES (3 winners): - Best Module 1st place: $1,500 - Best Module 2nd place: $500 - Best Workflow: $500 TRACK A - BEST MODULE ($1,500 + $500) A signed handler bundle that adds a new integration or capability. Examples already live: HubSpot (free, Bearer), Salesforce (paid, OAuth + monthly subscription). Yours could be anything: Notion, Asana, Airtable, Zendesk, Intercom, Linear, Jira, Zoom, DocuSign, Stripe, QuickBooks - pick a real product businesses use. Judging: real usefulness (solves a problem a small team would pay for) - coverage (the top 6-10 actions someone would want, not just one) - trust surface (safe auth pattern, secrets never touch the DB, honest errors) - docs (a README that lets a stranger install and use it in under 10 minutes). TRACK B - BEST WORKFLOW ($500) An end-to-end automation built on RailCall - using existing modules (or one you build) to solve a concrete recurring task. Think "when a lead fills the form, enrich -> score -> route to the right AE in Slack -> open a HubSpot deal -> log to Airtable." Judging: end-to-end story (real trigger to real business value) - reliability (handles missing fields, API 429s, dedup) - the receipts look good (the signed audit trail tells a coherent story). WHAT WE PROVIDE - Full docs: https://railcall.ai/docs - 30-minute zero-to-published tutorial: https://railcall.ai/docs/marketplace-developer/your-first-module - API reference: https://railcall.ai/docs/api-reference - Live reference modules to read: sami666/hubspot (free), sami666/salesforce (paid) - Free Team seats for the contest - DM in Discord for access to paid features while you build - Support: our Discord - https://discord.gg/22bu9Xpt4z - real humans answer within a day HOW TO ENTER 1.

Hi RailCall team — The contest page says entrants keep their module IP, but Freelancer's standard contest handover asks winners to sign an IP Transfer Agreement before the prize is released. Which rule will apply to the winning entries?

Submitted two contest-tagged listings #62 (contest:2026Q3), both tested end-to-end against a real Zendesk account before publishing — no mocks: Module (Track A): saifbrand/zendesk — 10 support-ticket actions (create, get, list, search, update, reply, tag, apply-macro, find/create user). Auth via a Zendesk OAuth client (client_credentials grant) — no password, no browser redirect, works even as Zendesk retires plain API tokens. Workflow (Track B): saifbrand/zendesk-triage-escalate — a 5-node DAG built on the module above (create → classify → escalate → tag → note). Both the urgent and non-urgent branches were verified COMPLETED via RailCall's real workflow_engine against live data. Full READMEs (install, credential setup, working examples, known limitations) are linked from each listing. Happy to answer any questions during review

Hi! Quick clarification for Track A. If a provider is mentioned in Station’s built-in integration catalog, but has no executable commands, API handlers, or Marketplace listing, would a complete real-API module for that provider qualify as a new integration?

#34 I have officially submitted my entry for the 2026Q3 Module and Workflow Contest! I built a production-grade Zendesk Integration Module (Track A) and a Support Triage Workflow (Track B). Both are fully signed, verified, and live on the RailCall Marketplace. ? Zendesk Module: https://railcall.ai/marketplace/jayy/zendesk-integration ($49 Paid) ? Support Triage Workflow: https://railcall.ai/marketplace/jayy/support-triage (Free) Both entries are fully verified offline with tests. Looking forward to your feedback!

Hello RailCall team, I completed a real RailCall Airtable module and published it to the marketplace with the required contest:2026Q3 tag. The source code and README are also pushed publicly to GitHub. The module adds governed Airtable actions for base/table lookup, record list/search/get, create, batch append, update, upsert, and delete. Mutating actions are marked as external side effects, aligning with RailCall’s preview -> approve -> execute -> signed receipt model. I’m also attaching screenshots showing the terminal publish result, publisher key registration, GitHub push, and repository files. Marketplace Listing: https://railcall.ai/marketplace/abdullah-aleem/airtable README: https://github.com/abdullahaleem0334/railcall-airtable-module/blob/main/README.md #15 by @abdullaha0624
