Description
Build a private GoHighLevel Marketplace app replicating the WAVV integration model: installed from the GHL App Marketplace at the agency level, deployed to our sub-account, and rendered natively inside the GHL UI — sidebar app plus in-page dialer controls on smart lists and opportunity pipelines. No external website, no separate URL, no custom menu link to an outside domain. Scope: Twilio-powered engine (click-to-dial, single-line power dial, 3-line parallel dial with answering machine detection), voicemail drop, call recording, and two-way sync of contacts, conversations, dispositions, and workflow triggers via GHL API v2, OAuth 2.0, SSO, and webhooks. Proposals must reference prior GHL Marketplace apps you have shipped and describe your approach to embedding UI inside GHL pages.
