Used by

• Chat xAI (Grok)
• Aria and agents (Settings › Providers)

Pick a method

Method	Use it when
Aria & agents Recommended	Chat with Aria or an agent on xAI models. The key is kept in Settings › Providers.
Workflow nodes	Use Chat xAI (Grok) in a workflow. The key is a saved credential.

Set it up

Aria & agents (recommended)

1. Create a key. In the xAI console, open API Keys, create a key and copy it. It starts with xai-.
2. Open Settings › Providers and click + Add provider.
3. Pick xAI as the Provider, give it a Label and paste the key into API key.
4. Type the Model id, then click Add.
5. Optionally click Set as default, so Aria and agents set to Same as Aria use it.

Check it's connected — 

Open a chat, pick the provider’s model in the model menu and send Hello: the reply comes from xAI. A wrong key shows a provider error in the chat right away.

Workflow nodes

1. Create a key. In the xAI console, open API Keys, create a key and copy it. It starts with xai-.

2. Save it in AWFlow. Open Credentials and click Add Credential (or + Add Credential in the node’s Authentication field), then fill the New Credential form. In the browser side panel the form comes in two steps: tap Simple Credential (or click Continue), then fill the rest.

Where your token lives

Where your token lives — 

The credential is stored where you choose when you create it:

• Local (this browser only): encrypted in this browser. The encryption key is kept on the same device, so turn on the local secret vault to lock it with a passphrase only you know.
• Cloud (synced to your account): sent over an encrypted connection and stored encrypted on AWFlow’s server, so it works on your other devices.

When a step runs, your browser sends it only to api.x.ai. AWFlow’s servers never relay the call.

Keys added in Settings › Providers are separate: they stay on this device only, encrypted, and are never synced to your account.

Common issues

• A 401, “invalid API key” or “Incorrect API key” error. The key was mistyped, revoked, or belongs to another account. Create a new key and update the credential (or the provider in Settings › Providers).
• A 429 or “quota” error. The account is out of credit or over its rate limit. Add credit or wait, then run again.
• An embeddings node fails with 401 while a chat node with the same key works. The credential is a Bearer Token. Embeddings nodes pass the value to the provider as it is, so use a JWT credential that holds only the key.
