Vectara has introduced a new Personal API key that provides simplicity and added permissions for developers. The Personal API key offers broader permissions compared to traditional API keys, but remains simple to use like traditional API keys. This new feature is ideal for applications requiring administrative operations, such as creating or managing corpora, while still being suitable for query-focused applications. Developers should take care to securely manage their API keys and choose the most suitable key for their application, considering the extra permissions of Personal API keys.
