# Send SignNow to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
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.
```
### Upgrade existing

```text
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.

## Documentation

### 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

Sign in or create an account at maton.ai
Go to maton.ai/settings
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:

{
  "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

StatusMeaning400Missing SignNow connection or bad request401Invalid or missing Maton API key403Insufficient permissions or subscription required404Resource not found405Method not allowed429Rate limited4xx/5xxPassthrough error from SignNow API

SignNow errors include detailed messages:

{
  "errors": [
    {
      "code": 65578,
      "message": "Invalid file type."
    }
  ]
}

### Troubleshooting: API Key Issues

Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

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

Ensure your URL path starts with signnow. For example:

Correct: https://gateway.maton.ai/signnow/user
Incorrect: https://gateway.maton.ai/user
