Fastbound API · fastbound bundle Build, debug, and reason about integrations with the FastBound API — the REST API behind FastBound's electronic A&D (acquisition & disposition) bound book and ATF Form 4473 software for FFL holders. Use this skill whenever the user mentions FastBound, FFL software, electronic bound book, A&D book, ATF compliance APIs, ATF Form 4473 automation, NFA dispositions, firearm acquisition/disposition records, FastBound webhooks, or asks about integrating a POS, e-commerce, ERP, range, or manufacturing system with FastBound. Also use when the user is calling endpoints under cloud.fastbound.com, working with OAuth authorization_code or device_code flows for FastBound, handling FastBound webhook signatures, or troubleshooting FastBound API errors. Even if the user does not say "FastBound" explicitly — for example "I need to log a firearm acquisition with serial number X to our bound book" — invoke this skill.
