# SDKs

From local development to production, Infisical SDKs provide the easiest way for your app to fetch back secrets from Infisical on demand.

* Install and initialize a language-specific client SDK into your application
* Provision the client scoped-access to a project and environment in Infisical
* Fetch secrets on demand

## FAQ

<AccordionGroup>
  <Accordion title="Isn't it inefficient if my app makes a request every time it needs a secret?">
    The client SDK caches every secret and implements a 5-minute waiting period before re-requesting it. The waiting period can be controlled by
    setting the `cacheTTL` parameter at the time of initializing the client.

    Note: The exact parameter name may differ depending on the language.
  </Accordion>

  <Accordion title="What if a request for a secret fails?">
    The SDK caches every secret and falls back to the cached value if a request fails. If no cached
    value ever-existed, the SDK falls back to whatever value is on the process environment.
  </Accordion>

  <Accordion title="Can I attach the environment variables to my process environment?">
    Yes you can! The client SDK provides a method to attach the secrets to your process environment. When using the `listSecrets()` method, you
    can pass a `attachToProcessEnv` parameter, which tells the SDK to attach all the found secrets to your process environment.

    Note: The exact parameter name may differ depending on the language.
  </Accordion>

  <Accordion title="What if a request for a secret fails?">
    The SDK caches every secret and falls back to the cached value if a request fails. If no cached value is found, and the request fails, then the SDK throws an error.
