14.3Creating the credential in n8n

The node uses a credential of type SYNERGY Management Gateway API.

To create the credential:

1. 1In n8n, open Credentials (or add the node to a workflow and choose Create new credential from its credential field).
2. 2Search for SYNERGY Management Gateway API and select it.
3. 3Fill in the fields described in the table below.
4. 4Select Save. n8n tests the credential automatically.

If the gateway is published under an application path, include it: for example https://gateway.example.com/backend/api. The most common mistake is to leave /api off the end of the URL. The node calls paths such as /ad/users and /saved-ldap-filters, which only reach the right place when the base URL ends in /api.

When you save, the credential test calls GET /metadata. That call needs only a valid API key and no particular permission, so a successful test proves the URL and the key are right. It does not prove that the Client ID is correct or that the role holds the permissions your workflow uses; the first real operation will tell you that.

The credential refuses an http:// URL, both in the test and when the node runs, so that the API key is never sent over an unencrypted connection.

Important: Ignore SSL Errors disables certificate checking and exposes the API key to anyone who can intercept the connection. Never turn it on for a production gateway. Install a certificate that the n8n host trusts instead.
