Authentication

Vectara API key api_key discovered Get key ↗

x-api-key: <credential>

Log in to the Vectara Console, then go to Authorization → API Keys and create or copy a Personal API key. The docs recommend exporting it as VECTARA_API_KEY for examples and SDK usage.

Vectara OAuth app client credentials oauth2_cc discovered Set up OAuth ↗

Authorization: Bearer <credential>

Log in to the Vectara Console. Vectara RBAC docs mention app clients as API-role principals, and the REST API docs say you can authenticate with OAuth 2.0 client credentials by obtaining a JWT from https://auth.vectara.io/oauth2/token. Create an app client in the console, then use its client credentials to request a bearer token from that token endpoint.
