SignNow API integration with managed OAuth. E-signature platform for sending, signing, and managing documents. Use this skill when users want to upload documents, send signature invites, create templates, or manage e-signature workflows. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. Calls run through the `maton` CLI with OAuth login, or over raw HTTP with a Maton API key where the CLI cannot be installed. The endpoints documented here are the intended surface, not a technical limit — the `maton api` passthrough can reach others the connection permits. Default to read and list calls, and confirm every write or new connection with the user.
Harden every multipart upload example: the assembled request body now goes to an owner-only file created with umask 077 and mktemp, removed by a trap on any exit, instead of a predictable shared /tmp path that could be pre-created by another user and left behind holding a copy of the uploaded file
