Integrations Authorization

Check out our Integrations Authorization Guide.

Making requests

Once you've created a Client, you can make requests using the #get, #post, and #delete methods. These methods return promises containing a response object detailed in the Responses section.

// GET api.dwolla.com/customers?limit=10&offset=20
dwolla
  .get("customers", { limit: 10, offset: 20 })
  .then((res) => console.log(res.body.total));

// POST api.dwolla.com/resource {"foo":"bar"}
dwolla
  .post("customers", {
    firstName: "Jane",
    lastName: "Doe",
    email: "[email protected]",
  })
  .then((res) => console.log(res.headers.get("location")));

// POST api.dwolla.com/resource multipart/form-data foo=...
var body = new FormData();
body.append("file", fs.createReadStream("mclovin.jpg"), {
  filename: "mclovin.jpg",
  contentType: "image/jpeg",
  knownLength: fs.statSync("mclovin.jpg").size,
});
body.append("documentType", "license");
dwolla.post(`${customerUrl}/documents`, body);

// DELETE api.dwolla.com/resource
dwolla.delete("resource");

Setting headers

To set additional headers on a request you can pass an object as the 3rd argument.

For example:

dwolla.post(
  "customers",
  { firstName: "John", lastName: "Doe", email: "[email protected]" },
  { "Idempotency-Key": "a52fcf63-0730-41c3-96e8-7147b5d1fb01" }
);

Responses

dwolla.get("customers").then(
  function(res) {
    // res.status   => 200
    // res.headers  => Headers { ... }
    // res.body     => Object or String depending on response type
  },
  function(error) {
    // when the server return a status >= 400
    // error.status   => 400
    // error.headers  => Headers { ... }
    // error.body     => Object or String depending on response type
  }
);
