Anything you send to Rulebase programmatically travels over an API key: pushing conversations from a helpdesk we don’t have a native integration with, or filing back-office work items from your internal admin tool. One key is usually enough to get started. The base URL is region-specific. Rulebase runs separate US and EU deployments, and a key issued in one region does not work in the other. A valid key sent to the wrong host returns the same 401 Unauthorized as a mistyped one, so the error message won’t tell you which mistake you made.

​
Before you start

  • You need permission to manage integrations. Admin roles have it; if the Create API key button is greyed out, that’s what’s missing.
  • Know which region your organization is on; the next section explains how to tell.
  • Have somewhere to put the key before you create it. A secrets manager or your deployment platform’s environment variables are both fine. A chat message is not, and you only get one chance to copy it.

​
Create a key

API keys live on the API keys tab in Connections settings.
  1. Go to Settings > Connections.
  2. Open the API keys tab.
  3. Click Create API key.
  4. Copy the key from the API key created dialog, using the copy button next to it.
  5. Paste it into your secret store, then click Done.
API key created dialog showing the full API key with a copy button and a warning that the key cannot be viewed again There are no options to fill in. The key is generated the moment you click, works straight away, and never expires on its own.
The dialog is the only place the full key is ever shown. Once you close it, Rulebase can’t display the key again, and there is no “reveal” action on the list. If you lose a key, create a new one and revoke the old one.
Production keys start with rk_live_. Back on the list, each row shows only the first 16 characters followed by an ellipsis, which is enough to tell your keys apart when you come back to revoke one, and not enough to authenticate with.

​
Find your region’s base URL

Your region is the one you sign in to. If you log in at app.rulebase.co you’re on US; if you log in at eu.app.rulebase.co you’re on EU. There’s no region setting to look up, and no way to change it yourself. Rulebase exposes one public API host per region: Every public endpoint is versioned under /v1. Existing integrations that use deprecated aliases continue to work during their sunset period, and those responses include Deprecation, Sunset, and successor Link headers. Use the canonical /v1 path for new integrations and whenever you update an existing one.
If you’re on EU, put the base URL in one configuration value that every call site reads, rather than writing the host into each request. Otherwise a single unprefixed URL can survive into production and show up later as a 401 that looks like a credentials problem.

​
Send your first request

Authenticate by putting the key in an Authorization: Bearer header. Listing conversation uploads is a good first call because it only reads, so you can run it against a live organization without changing anything:
A working key returns 200 with an envelope, even when your organization hasn’t uploaded anything yet:
A key that Rulebase doesn’t recognize returns 401 with this body in either region:
If you get the 401, check these three things:
  • The host. If you sign in at eu.app.rulebase.co, confirm you’re calling eu.api.rulebase.co and not api.rulebase.co. Rule this out first, because nothing in the response hints at it.
  • The header. The value is the word Bearer, a space, then the key. A trailing newline from a shell variable is enough to break it.
  • The key itself. Check the first 16 characters against the list in Settings > Connections. If the row isn’t there, the key was revoked.
rulebase doctor (from npm install -g @rulebase/cli) tries your key against both regions and names the one that accepts it, which settles the first bullet in one command. See the Rulebase CLI guide.

​
What a key carries

Every key has the same properties:
  • Organization-wide access. A key authenticates as your organization, not as the person who created it. Requests made with it aren’t attributed to you and aren’t limited by your role.
  • No per-key scopes. There are no read-only keys, no per-endpoint permissions, and no IP restrictions. Every key can reach every endpoint that accepts API-key authentication.
  • Tied to one region. Each region keeps its own key store, so a key created in the EU app authenticates only against EU hosts.
  • No expiry. A key stays valid until someone revokes it.
Because a key is org-wide and open-ended, treat it as a shared production credential. Creating one key per integration costs nothing and means you can retire a single system later without breaking the others.

​
Revoke a key

Revoking is a delete. There’s no disable-and-re-enable, so only do this once you’re sure the key is out of service or you know it’s leaked.
  1. Go to Settings > Connections and find the key in the API keys list, matching on its prefix.
  2. Open the overflow menu at the end of its row.
  3. Click Delete.
  4. Confirm with Delete in the dialog.
Confirmation dialog warning that deleting an API key is permanent and that applications using the key will lose access The key stops working straight away, and anything still sending it starts getting 401 Unauthorized. Rulebase keeps the data that was uploaded with the key; only the credential goes away. To rotate rather than retire an integration, create the replacement key and deploy it first, then come back and delete the old one.
