 Inputs and outputs (including exceptions) to and from Durable Functions APIs are [durably persisted](./durable-functions-serialization-and-persistence.md) in your [storage provider of choice](./durable-functions-storage-providers.md). If those inputs, outputs, or exceptions contain sensitive data (such as secrets, connection strings, personally identifiable information, etc.) then anyone with read access to your storage provider's resources would be able to obtain them. To safely deal with sensitive data, it is recommended users to fetch that data _within activity functions_ from either Azure Key Vault or environment variables, and to never communicate that data directly to orchestrators or entities. That should help prevent sensitive data from leaking into your storage resources.
 
 > [!NOTE]
-> This guidance also applies to the `CallHttp` orchestrator API, which also persists its request and response payloads in storage. If your target HTTP endpoints requires authentication, which may be sensitive, it is recommended that users to implement the HTTP Call themselves inside of an activity, or to use the built-in managed identity support offered by `CallHttp`, which does not persist any credentials to storage.
