n8n-nodes-keycloak-password

An n8n community node + credential for calling APIs that sit behind Keycloak,
authenticating with the OpenID Connect password grant (Resource Owner Password
Credentials).

It replaces the manual login.py token request: the credential stores the form
values securely (n8n encrypts secret fields at rest), and the node posts them to the
token endpoint you configure, returning the token response.

What's included

• Credential Keycloak Password API — securely stores the keys posted to the
  token endpoint: Grant Type, Client ID, Client Secret, Username, Password and Scope.
• Node Keycloak HTTP Request — set the token endpoint in the URL field; the node
  sends the stored credential values as application/x-www-form-urlencoded and returns
  the JSON response.

Credential fields

Build & install locally

npm install
npm run build       # n8n-node build (compiles TS + copies icons)
npm run dev         # or: run a local n8n with the node hot-linked

# manual link into your n8n custom folder
mkdir -p ~/.n8n/custom
cd ~/.n8n/custom && npm link n8n-nodes-keycloak-password   # after `npm link` in this repo

Restart n8n, then add the Keycloak Password API credential and use the
Keycloak HTTP Request node — paste your token endpoint into the node's URL field.

Security notes

• Secrets are entered as password fields and encrypted by n8n's credential store.
• Do not commit real secrets. login.py is gitignored.
• The password grant is fine for trusted server-to-server / service-account logins,
  which is this node's use case.
