## Generic Webhook External Secrets Operator can integrate with simple web apis by specifying the endpoint ### Example First, create a SecretStore with a webhook backend. We'll use a static user/password `root`: ```yaml {% raw %} apiVersion: external-secrets.io/v1beta1 kind: SecretStore metadata: name: webhook-backend spec: provider: webhook: url: "http://httpbin.org/get?parameter={{ .remoteRef.key }}" result: jsonPath: "$.args.parameter" headers: Content-Type: application/json Authorization: Basic {{ print .auth.username ":" .auth.password | b64enc }} secrets: - name: auth secretRef: name: webhook-credentials {%- endraw %} --- apiVersion: v1 kind: Secret metadata: name: webhook-credentials data: username: dGVzdA== # "test" password: dGVzdA== # "test" ``` NB: This is obviously not practical because it just returns the key as the result, but it shows how it works **NOTE:** In case of a `ClusterSecretStore`, Be sure to provide `namespace` in all `secrets` references with the namespaces where the secrets reside. Now create an ExternalSecret that uses the above SecretStore: ```yaml apiVersion: external-secrets.io/v1beta1 kind: ExternalSecret metadata: name: webhook-example spec: refreshInterval: "15s" secretStoreRef: name: webhook-backend kind: SecretStore target: name: example-sync data: - secretKey: foobar remoteRef: key: secret --- # will create a secret with: kind: Secret metadata: name: example-sync data: foobar: c2VjcmV0 ``` #### Limitations Webhook does not support authorization, other than what can be sent by generating http headers !!! note If a webhook endpoint for a given `ExternalSecret` returns a 404 status code, the secret is considered to have been deleted. This will trigger the `deletionPolicy` set on the `ExternalSecret`. ### Templating Generic WebHook provider uses the templating engine to generate the API call. It can be used in the url, headers, body and result.jsonPath fields. The provider inserts the secret to be retrieved in the object named `remoteRef`. In addition, secrets can be added as named objects, for example to use in authorization headers. Each secret has a `name` property which determines the name of the object in the templating engine. ### All Parameters ```yaml apiVersion: external-secrets.io/v1beta1 kind: ClusterSecretStore metadata: name: statervault spec: provider: webhook: # Url to call. Use templating engine to fill in the request parameters url: # http method, defaults to GET method: # Timeout in duration (1s, 1m, etc) timeout: 1s result: # [jsonPath](https://jsonpath.com) syntax, which also can be templated jsonPath: # Map of headers, can be templated headers: :

# Body to sent as request, can be templated (optional) body: # List of secrets to expose to the templating engine secrets: # Use this name to refer to this secret in templating, above - name: secretRef: namespace: # Only used in ClusterSecretStores name: # Add CAs here for the TLS handshake caBundle: caProvider: type: Secret or COnfigMap name: namespace: # Only used in ClusterSecretStores key: ```
