Now that we have our Cloudinary account set up, we will continue. Open your .env file placed at the root of the SmartExchange code and add the following:

// SNIPP SNIPP
GCP_API_KEY=AIzaSyAmMqOXsDk8HflP_iDXERyiU2FB9FhDCQk
// SNIPP SNIPP

This is the API key that we used earlier to make a request to the Google Cloud Vision API. We are going to use it programmatically.
