Title: Install and connect Description: Install the OpenPost community node and configure a least-privilege credential. Canonical: https://docs.openpo.st/automate/n8n/setup Source: [https://docs.openpo.st/automate/n8n/setup](https://docs.openpo.st/automate/n8n/setup) # Install and connect ## Install the node In n8n, open **Settings → Community nodes**, select **Install**, and enter: ```text @getopenpost/n8n-nodes-openpost ``` Your n8n runtime must use Node.js 22.22 or newer. ## Create an OpenPost credential Create a developer token in OpenPost under **Settings → Personal → Developer**. Use a workspace-bound `api:write` token for a workflow that creates or changes content. Name the token after the n8n workflow or instance so it is easy to revoke later. Add an **OpenPost API** credential in n8n: - **Base URL:** `https://app.openpo.st`, or the public origin of your self-hosted instance. Do not append `/api` or `/api/v1`. - **API Token:** the OpenPost developer token. If n8n runs in Docker, `localhost` means the n8n container. Use the OpenPost Compose service name when both services share a network, or `host.docker.internal` when OpenPost runs on the host. ## Test access Import the package's `list-workspaces` example, select the OpenPost credential, and run it. The returned items show which workspaces the token can access. Do this read-only check before adding write actions. A workspace-bound token cannot write to another workspace even when a node receives its ID from earlier input.
