This article provides guidance on using Dapr's secrets API in your code to leverage the [secrets store building block]({{}}). The secrets API allows you to easily retrieve secrets in your application code from a configured secret store.
Example
The below code example loosely describes an application that processes orders. In the example, there is an order processing service, which has a Dapr sidecar. The order processing service uses Dapr to store a secret in a local secret store.

Set up a secret store
Before retrieving secrets in your application's code, you must have a secret store component configured. For the purposes of this guide, as an example you will configure a local secret store which uses a local JSON file to store secrets.
Note: In a production-grade application, local secret stores are not recommended. You can find other alternatives [here]({{}}) to securely manage your secrets.
Create a file named secrets.json
with the following contents:
{
"secret": "Order Processing pass key"
}
Create a directory for your components file named components
and inside it create a file named localSecretStore.yaml
with the following contents:
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
name: localsecretstore
namespace: default
spec:
type: secretstores.local.file
version: v1
metadata:
- name: secretsFile
value: secrets.json #path to secrets file
- name: nestedSeparator
value: ":"
Note: the path to the secret store JSON is relative to where you call
dapr run
from.
To configure a different kind of secret store see the guidance on [how to configure a secret store]({{}}) and review [supported secret stores]({{}}) to see specific details required for different secret store solutions.
Get a secret
Run the Dapr sidecar with the application.

Get the secret by calling the Dapr sidecar using the secrets API:
curl http://localhost:3601/v1.0/secrets/localsecretstore/secret
For a full API reference, go [here]({{< ref secrets_api.md >}}).
Calling the secrets API from your code
Once you have a secret store, call Dapr to get the secrets from your application code. Below are code examples that leverage Dapr SDKs for retrieving a secret.
