SignNow

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.

Installer
$clawhub install signnow

SignNow

Access the SignNow API with managed OAuth authentication. Upload documents, send signature invites, manage templates, and automate e-signature workflows.

Quick Start

# Get current user info
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/signnow/user')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://gateway.maton.ai/signnow/{resource}

The gateway proxies requests to api.signnow.com and automatically injects your OAuth token.

Authentication

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"

Getting Your API Key

  1. Sign in or create an account at maton.ai
  2. Go to maton.ai/settings
  3. Copy your API key

Connection Management

Manage your SignNow OAuth connections at https://ctrl.maton.ai.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=signnow&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'signnow'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Get Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Response: json { "connection": { "connection_id": "5ff5474b-5f21-41ba-8bf3-afb33cce5a75", "status": "ACTIVE", "creation_time": "2026-02-08T20:47:23.019763Z", "last_updated_time": "2026-02-08T20:50:32.210896Z", "url": "https://connect.maton.ai/?session_token=...", "app": "signnow", "metadata": {} } }

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple SignNow connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/signnow/user')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '5ff5474b-5f21-41ba-8bf3-afb33cce5a75')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

Notes

  • Documents must be in PDF format for upload
  • Supported file types: PDF, DOC, DOCX, ODT, RTF, PNG, JPG
  • System folders (Documents, Templates, Archive, Trash Bin) cannot be renamed or deleted
  • Creating signing links requires documents to have signature fields
  • Custom invite subject/message requires a paid subscription
  • Rate limit in development mode: 500 requests/hour per application
  • IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments

Error Handling

Status Meaning
400 Missing SignNow connection or bad request
401 Invalid or missing Maton API key
403 Insufficient permissions or subscription required
404 Resource not found
405 Method not allowed
429 Rate limited
4xx/5xx Passthrough error from SignNow API

SignNow errors include detailed messages: json { "errors": [ { "code": 65578, "message": "Invalid file type." } ] }

Troubleshooting: API Key Issues

  1. Check that the MATON_API_KEY environment variable is set:
echo $MATON_API_KEY
  1. Verify the API key is valid by listing connections:
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

  1. Ensure your URL path starts with signnow. For example:
  • Correct: https://gateway.maton.ai/signnow/user
  • Incorrect: https://gateway.maton.ai/user
