# Configure a Connector Proxy
|
|
|
|
## Setting the Environment Variable
|
|
|
|
Once a `Connector Proxy` has been deployed, to integrate it with SpiffArena we simply need to update an environment variable and restart the backend. If using the [Getting Started Guide](https://www.spiffworkflow.org/posts/articles/get_started/) open the docker-compose.yml file, else edit the environment variable in the way appropriate for your deployment. The variable we need to change is called `SPIFFWORKFLOW_BACKEND_CONNECTOR_PROXY_URL`.

## Testing
|
|
|
|
Create a new process model as described in the [Getting Started Guide](https://www.spiffworkflow.org/posts/articles/get_started/). Add a `Service Task` and in its properties panel you will see a drop down to pick which connector in your `Connector Proxy` to call. In this demo we deployed http get and post connectors:
|
|
|
|
|
|
|
|
Choose the `http/GetRequest` operator ID and enter the [dog fact api](https://dog-api.kinduff.com/api/facts) URL. Remember to quote it since parameters are evaluated as Python expressions.
|
|
|
|
|
|
|
|
Run the process and once complete you can see the response in the workflow:
|
|
|
|
|
|
|
|
You have successfully configured a `Connector Proxy` for use with `SpiffArena`. You made a call from a workflow to get a dog fact. Now imagine that call was to talk to an external system relevant to your business processes.
