Proxy Configuration

Every LinkedIn account connected through We-Link requires a proxy. The proxy is used during login and for all subsequent requests to LinkedIn, ensuring each account operates from a consistent IP address.

warning

Exactly one proxy method must be provided when calling the login endpoint. If no valid proxy configuration is supplied, the request will be rejected.

Proxy Methods

We-Link supports two proxy options:

Method	Description	Managed by
Internal Proxy (recommended)	We-Link assigns a geo-matched, high-quality residential proxy	We-Link
Customer Proxy	You provide your own proxy credentials	You

---

Internal Proxy (Recommended)

We-Link automatically assigns a dedicated, localized IP address based on the country code you specify. This is the simplest option — no infrastructure to manage on your side.

Required Field

Field	Type	Description
location	string	Supported country code (e.g., "US", "IN", "GB")

Example

{
  "email": "user@example.com",
  "password": "securePassword123",
  "twoFASecret": "JBSWY3DPEHPK3PXP",
  "proxy": {
    "location": "US"
  }
}

How It Works

1. We-Link searches for an available proxy in the requested location.
2. If available, the proxy is assigned to the account automatically.
3. If no proxy is available for that location, the request fails with a 400 error:

{
  "message": "No proxy available for location: {US}",
  "error": "Bad Request",
  "statusCode": 400
}

Billing & Location

caution

If you log in using one location and later log in again with a different location, a new proxy will be allocated. Since proxy allocation is location-based, this may result in additional charges.

Always provide the correct location to avoid unnecessary credit consumption.

Customer Proxy

Provide your own proxy credentials if you have dedicated infrastructure or need a specific IP address.

Required Fields

Field	Type	Description
host	string	Proxy host or IP address
port	number	Proxy port
username	string	Proxy username
password	string	Proxy password

Example

{
  "email": "user@example.com",
  "password": "securePassword123",
  "twoFASecret": "JBSWY3DPEHPK3PXP",
  "proxy": {
    "host": "192.168.1.1",
    "port": 8080,
    "username": "proxy_user",
    "password": "proxy_password"
  }
}

Behavior

• The proxy is validated before the login session starts.
• If validation fails, login is rejected.
• We-Link does not manage lifecycle or billing for customer-provided proxies — you are responsible for uptime and rotation.

---

Proxy Validation

All proxies — internal or customer-provided — are validated before initiating a login session:

1. We-Link performs an initial proxy connectivity check.
2. If it fails, a secondary validation attempt is made automatically.
3. If both attempts fail, the request is rejected:

{
  "statusCode": 500,
  "message": "Second proxy attempt failed, management notified"
}

Monitoring Proxy Health

Once an account is connected, you can check and recover the proxy at any time using the proxy_status endpoint.

Endpoint: POST /api/v1/proxy_status

{
  "accountId": "1234ab5678290....",
  "reactivate": true
}

Response:

{
  "message": "Proxy is active"
}

Setting "reactivate": true attempts to reactivate the proxy if it's in an error state.

---

Switching Proxies

You can change the proxy for an existing account without disconnecting it:

Endpoint	Description
POST /api/v1/switch_to_internal_proxy	Switch to a We-Link internal proxy
POST /api/v1/rotate_internal_proxy	Rotate to a new internal proxy in the same location
POST /api/v1/switch_to_customer_proxy	Switch to your own proxy

These endpoints are available in the API Reference.

Best Practices

• Use internal proxies unless you have a specific reason to bring your own — We-Link handles rotation, uptime, and geo-matching automatically.
• Match the proxy location to the LinkedIn account's usual login region to minimize LinkedIn security flags.
• Don't change proxy locations frequently — each location change allocates a new proxy and may incur additional charges.
• Monitor proxy health using the proxy_status endpoint, especially if you see PROXY_ERROR failures in webhooks.
• For customer proxies, use high-quality residential or ISP proxies — datacenter proxies are more likely to be flagged by LinkedIn.
