Developer settings

Where: Settings, Developers

This tab is the entry point to everything programmatic. The reference documentation lives in its own tabs; this page is about the controls in the UI.

Access

Your API key

Your API key lives in UseNadia under Settings → Developers, in the Access section, under API Key. Click the reveal icon to show it, then copy. You can rotate it from the same place, rotating immediately invalidates the old key, so update anything using it (scripts, n8n, MCP clients, the CLI) at the same time.

Caution

Never share your UseNadia API key or OAuth token. Not in a GitHub issue, not in a chat, not in a bug report. Anyone holding it can post to every channel in your organisation, read your inbox and pull your analytics.

If one leaks, rotate it under Settings → Developers → Public API. Rotating invalidates the old key immediately, so update whatever was using it at the same time.

Rotating is the fix if a key leaks, and the only fix: keys do not expire on their own.

MCP client configuration

UseNadia generates the configuration block for connecting an AI client through MCP. Pick your client and whether you are using a local CLI or a remote client, then copy the block.

CLI, skills and the n8n node

The same section offers the setup for the CLI, for local use or for CI, an Open Wizard button that generates API code, and the configuration for the n8n node — see Third-party integrations.

Apps

This is where you register an OAuth application, for building something other UseNadia users will authorise, rather than something that acts as you.

1. Create OAuth App

   Name and redirect URL are required. Description and icon are optional, and both are shown to users on the consent screen, so they are worth filling in.

2. Copy the credentials

   You get a client ID and a client secret.

3. Implement the flow

   See OAuth2 for developers.

Caution

Rotating the client secret invalidates the old one immediately. Every token exchange using the old secret starts failing, so deploy the new secret first.

API key or OAuth app?

	API key	OAuth app
Acts as	You	Whoever authorises it
Good for	Your own scripts, automations, self-hosted tools	A product other UseNadia users will use
Setup	Copy the key	Register an app, implement the flow
Revoking	Rotate the key	The user revokes in Approved Apps

If you are automating your own posting, use the API key. Build an OAuth app only when other people’s accounts are involved.
