## Component format

To setup Azure CosmosDBGremlinAPI binding create a component of type `bindings.azure.cosmosdb.gremlinapi`. See [this guide]({{< ref "howto-bindings.md#1-create-a-binding" >}}) on how to create and apply a binding configuration.


```yaml
apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: bindings.azure.cosmosdb.gremlinapi
  version: v1
  metadata:
  - name: url
    value: wss://******.gremlin.cosmos.azure.com:443/
  - name: masterKey
    value: *****
  - name: username
    value: *****
  ```

{{% alert title="Warning" color="warning" %}}
The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}).
{{% /alert %}}

## Spec metadata fields
