n8n-nodes-yealinkymcs

This is an n8n community node for the Yealink Management Cloud Service (YMCS) Open API V4X. It lets you manage Yealink VoIP phones and room devices directly from your n8n workflows, including provisioning, configuration, diagnostics, and firmware management.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

npm install @dszp/n8n-nodes-yealinkymcs

Or install from the n8n GUI: Settings > Community Nodes > Install and enter @dszp/n8n-nodes-yealinkymcs.

Credentials

You need a Yealink YMCS enterprise account with API access enabled.

1. Log into the Yealink YMCS portal
2. Navigate to Enterprise Settings > API Service
3. Copy the AccessKey ID (Client ID) and AccessKey Secret (Client Secret)
4. In n8n, create a new Yealink YMCS API credential
5. Select your Region (US, EU, or AU) and enter the Client ID and Client Secret

Note: Credential auto-validation is not available due to the Yealink API requiring legacy TLS renegotiation. After saving your credentials, test them by running a Device > Get Many operation.

Resources

This node supports 15 resources covering the full YMCS API:

| Resource | Operations | |----------|-----------| | Alarm | Get Many | | Configuration | Create, Delete, Get, Get Many, Push, Update (for Device, Site, and Group configs) | | Device | Create, Create Many, Delete, Delete Many, Get, Get Configuration, Get Many, Update | | Device Accessory | Get, Get Many, Restart, Factory Reset | | Device Account | Bind, Get Many, Unbind | | Device Control | Factory Reset, Restart | | Device Group | Add Devices, Create, Delete, Get Devices, Get Many, Remove Devices, Update | | Device Identification | Get ID | | Diagnosis | Capture Screenshot, Export Config, Export Syslog, Get Network Interfaces, Get Status, Ping, Start Packet Capture, Stop Packet Capture, Traceroute | | Firmware | Get Many Custom, Get Many Official, Push, Push Official | | Model | Get Many | | Operation Log | Get Many | | RPS | Create, Create Many, Create Server, Delete, Delete Server, Get Many, Get Servers, Update, Update Server | | SIP Account | Create, Delete, Get Many, Update | | Site | Create, Delete, Get, Get Many, Update |

Compatibility

• Minimum n8n version: 1.0.0+
• Node.js: 18+ (tested with Node 22 and 24)
• Tested against Yealink YMCS API V4X (version 1.0.0)

Known Limitations

• The Yealink API servers require legacy TLS renegotiation (SSL_OP_LEGACY_SERVER_CONNECT), which is handled automatically by this node using a custom HTTPS agent. This means credential validation on save is not supported.
• Diagnosis operations (packet capture, ping, traceroute, etc.) return a diagnosisId. Poll the Get Status operation in your workflow to check for completion.
• The Yealink API misspells "official" as "offical" in firmware endpoints. The node matches the API spelling internally but uses the correct spelling in the UI.
