Facing CORS issue in token API about dwolla-v2-node

[tarricsookdeo]

Hi @ajithK24!

It seems like you are trying to access the token endpoint to create a new access token. The correct syntax for that is:

const Client = require('dwolla-v2').Client;

// instantiate client
const dwolla = new Client({
  environment: 'sandbox',
  key: <KEY>,
  secret: <SECRET>
});

// Request to token endpoint
dwolla.auth
  .client()
  .then(res => console.log(res))

/*A token object should be console logged
Token {
  client: Client {
    key: <KEY>,
    id: <ID>,
    secret: <SECRET>,
    environment: 'sandbox',
    onGrant: undefined,
    authUrl: 'https://accounts-sandbox.dwolla.com/auth',
    tokenUrl: 'https://api-sandbox.dwolla.com/token',
    apiUrl: 'https://api-sandbox.dwolla.com',
    auth: [Function: methods] {
      client: [Function: bound requestToken],
      refresh: [Function: bound refreshGrant]
    },
    Auth: [Function: bound AuthClass],
    Token: [Function: bound Token],
    get: [Function (anonymous)],
    post: [Function (anonymous)],
    delete: [Function (anonymous)],
    refreshToken: [Function (anonymous)],
    token: [Function (anonymous)]
  },
  access_token: <ACCESS TOKEN>,
  refresh_token: undefined,
  expires_in: 3448,
  scope: undefined,
  account_id: undefined
}
*/

However, our Node SDK takes care of token management for you. You can simply make requests against the client using the low level methods .get, .post, and .delete. The SDK will check if you have a valid token, and if not request a new one automatically.

Also, our Node SDK is a server side-library and shouldn't be accessed via a web browser. Try making requests via Postman, CURL, or another type of server-side client. You can read up more about this issue here: https://discuss.dwolla.com/t/dwolla-post-giving-me-a-cors-error/7652/3?u=spencer.

Ok @tarricsookdeo instead of node can we able to use JAVA ?

[tarricsookdeo]

@ajithK24 Yes, you are able to use Java to access Dwolla's API. We also have a Kotlin SDK that makes it easy to interact with the API using Java. Here is a link to it: https://github.com/Dwolla/dwolla-v2-kotlin
