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.

Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
Access the SignNow API with managed OAuth authentication. Upload documents, send signature invites, manage templates, and automate e-signature workflows.

https://gateway.maton.ai/signnow/{resource} The gateway proxies requests to api.signnow.com and automatically injects your OAuth token.
All requests require the Maton API key in the Authorization header: Authorization: Bearer $MATON_API_KEY Environment Variable: Set your API key as MATON_API_KEY: export MATON_API_KEY="YOUR_API_KEY"
Sign in or create an account at maton.ai Go to maton.ai/settings Copy your API key
Manage your SignNow OAuth connections at https://ctrl.maton.ai.
