I’m not following the examples in the documentation for how to search for a customer by email address. I’m using the dwolla-swagger-php from Github. The Dwolla docs talk about an example request URL like this: GET https://api.dwolla.com/customers?email=jane%40email.com. How am I supposed to make that call? Can someone provide sample code for PHP? How does this url fit into the API? I’m completely lost. Thanks in advance to anyone who can help me understand this.
