So I can get in...

Hi There,

I followed the quickstart guide for Python & Node, and when I try and run the local server and log into any of my accounts, I'm getting a 403 on the underlying request.

Am I naive, or should I be able to simple use my existing BofA login, for instance, and be able to successfully log in?

I should mention I'm using sandbox, would that have an effect?

I continue to get the following error:

Error Code: INVALID_FIELD
Error Type: INVALID_REQUEST
Error Message: country_codes must be a non-empty string array

.env

APP_PORT=8000
PLAID_CLIENT_ID='xxx'
PLAID_SECRET='xxx'
PLAID_PRODUCTS='transactions'
PLAID_COUNTRY_CODES='US'
PLAID_ENV='sandbox'

Does anyone else have this issue, if so were you able to fix it?

Edit: Had to wrap all country_codes: PLAID_COUNTRY_CODES with [] to look like country_codes: [PLAID_COUNTRY_CODES]

I'm running Big Sur v. 11.2.1 and am trying to use docker to launch the quickstart sandbox. I get an error when navigating to localhost:3000 in my browser. The make logs are saying my frontend can't proxy from the backend:

I thought maybe my .env file was wrong, here is the .env file:

PLAID_CLIENT_ID=user_good
PLAID_SECRET=pass_good

PLAID_REDIRECT_URI='http://localhost:3000'

Thanks for any help!

In the Plaid Docs, we have a custom user configuration

{
  "override_accounts": [
    {
      "type": "depository",
      "subtype": "checking",
      "transactions": [
        {
          "date_transacted": "2019-10-01",
          "date_posted": "2019-10-03",
          "currency": "USD",
          "amount": 100,
          "description": "1 year Netflix subscription"
        },
        {
          "date_transacted": "2019-10-01",
          "date_posted": "2019-10-02",
          "currency": "USD",
          "amount": 100,
          "description": "1 year mobile subscription"
        }
      ]
    }
  ]
}

Can you provide an exhaustive JSON while can support all the products?

My Products config PLAID_PRODUCTS=transactions,auth,identity,assets,liabilities,investments.

Error:

The error does not show up if we just keep PLAID_PRODUCTS as transactions,auth,identity

When I try to search for my bank (Capital One 360) using the institution selector, a spinner briefly appears after I type a few letters, and then I get the following message: Your search request timed-out, please try again with a better connection

Looking in the inspector, I see that a GET request to https://cdn.plaid.com/institutions/all/search?q=cap returns an HTTP 403 status. Opening that URL in a new tab gives the familiar AWS access denied error page.

The steps to getting this running seem pretty straightforward, so I don't see much room for user error here.

Line return jsonify({'error': {'display_message': 'Timed out when polling for Asset Report', 'error_code': e.code, 'error_type': e.type } })

"e" is not defined at this level.

The Python quickstart example JS code fails with:

Uncaught Error: Missing Link parameter. Link requires a key or token to be provided.

Been a pain getting this initial walk through app working using node .

[Error [UnsetVariableError]: No environment variable named "PLAID_CLIENT_ID"] {
message: 'No environment variable named "PLAID_CLIENT_ID"'

Solution:
Will be good to include dotenv module to externalise the properties , So they can be read from .env file.
https://www.npmjs.com/package/dotenv

add following line in file index.js

require('dotenv').config();

create .env file in node root dir with following lines:
APP_PORT=8000
PLAID_CLIENT_ID=
PLAID_SECRET=xx
PLAID_PUBLIC_KEY=xx
PLAID_PRODUCTS=transactions
PLAID_COUNTRY_CODES=US,CA,GB,FR,ES,IE
PLAID_ENV=sandbox

If following the Ruby instructions at https://dashboard.plaid.com/overview/sandbox, the institution search will fail to populate with any banks. Inspecting the javascript console will warn you that a valid list of products must be set.

The documentation neglects to mention the ENV['PLAID_PRODUCTS'] variable that is used on line 195 of views/index.erb and causes this error if it is not set. Once this is set, the institution search works fine. Since the purpose of this repo is to quickly build a templated Plaid application, this should be either hard-coded into index.erb or mentioned in the documentation near "Running the walkthrough application".

I used ["auth", "transactions", "income", "identity", "assets"], which is all of the products it accepts as valid.

When doing the quick start in either python or node, going to localhost:8000 just gives the text "../../html/index.html". Shouldn't it serve the file from that location rather than the path name text?

Decided to pick up plaid to play with it, and when installing on Python3 it fails due to wsgiref (there is a print statement in its setup.py), and after deleting that dependency, server.py also contains print statements.

The fix seems relatively straightforward of changing the calls in server.py to print function calls and conditionally installing wsgiref depending on if the target Python install is 2 or 3.

Happy to submit a PR to address this.

Pulled the quickstart repo to test out the Node walkthrough app.

After running npm install, I'm seeing some vulnerabilities in the express package highlighted by npm's audit tool.

I tried logging in my credentials to TJX Rewards and the error was:

However, I saw a 411 when viewing the response:

Content-Length: 411

Hi, I've been running the Plaid-Quickstart example in a Flutter WebView successfully for the past couple weeks, including last Sunday morning. Starting Sunday noon however, we noticed that the Keyboard for the Bank Login Screen does NOT stay up, and collapses when trying to click on either username or password fields. No changes to our code was made, and rolling back to older app builds does not remedy.

Were there any Sunday updates to the Plaid System that may have caused this?

I'm having a similar problem where I run the server.py and it allows me to access the http://127.0.0.1:5000/ website with the following available:

but then when i click open link, there is nothing available.

The ruby Quickstart app has two endpoints /get_acess_token (which takes a form field public_token) and /set_access_token (which takes a form field access_token). It calls them each under different circumstances in the template view.

The golang has only an endpoint /set_acess_token, which is defined in a function called getAccessToken, and which only references the public_token form field, not the access_token one. However, the golang template view calls set_access_token with an access_token field, which will always be ignored and the request will always fail because the public_token field is empty. It seems like this logic may have been copied over from the ruby one, changed a bit, and not properly resolved? I'd be happy to sort through it and submit a fix, but I just want to make sure that this is actually a mistake and not something I'm just misunderstanding.

The relevant code from the golang server is here, and it's added to the Gin router here. The JS logic that appears to be misusing this endpoint is here.

Problem

I wanted to use Node.js Quickstart to try to get data from a real bank account. I used Plaid Development environment for that.

The Quickstart fails with bad request, because redirect_uri must use HTTPS. Apparently the redirect URL http://localhost:8000/oauth-response.html works only in Sandbox environment, and Development and Production require HTTPS.

Expected behavior

• This limitation should be documented. I found no mention of that.
• The Quickstart could include steps for hosting on HTTPS.

Workaround

To serve the Quickstart on self-signed HTTPS on localhost:

1. Generate a self-signed certificate, e.g. in Bash:

openssl req -nodes -new -x509 -keyout server.key -out server.cert

2. Add additional modules to index.js and load the generated cert:

var fs = require('fs');
var https = require('https');
var key = fs.readFileSync('server.key');
var cert = fs.readFileSync('server.cert');

3. Replace the server creation with:

var server =
  https.createServer({
    key,
    cert
  }, app)
  .listen(APP_PORT, function() {
  console.log('plaid-quickstart server listening on port ' + APP_PORT);
});

4. Change your URLs to HTTPS in:

• oauth-response.html
• index.html (at the begining of render_page function)
• Env variable
• Plaid account configuration

Trying to run the python quickstart. Currently I have the following in server.py

PLAID_CLIENT_ID = '123XXXXXXXX123'
PLAID_SECRET = '321XXXXX321'
PLAID_ENV = 'sandbox'
PLAID_PRODUCTS = ['transactions']
PLAID_COUNTRY_CODES = ['US']

When I run server.py & check in the browser the Connect with Plaid button can't be selected & the list of banks never populate - it just seems to be repeatedly loading...

When I check index.html using dev tools I get the message "Uncaught Error: Missing Link parameter. Link requires a key or token to be provided." (see screenshot below).

Has anyone experienced this issue or know why it occurs? As best I can tell I've followed the quickstart instructions by entering client_id, secret & other variables...

When doing the default ruby quickstart walk through, the app breaks with the following ouput

POST https://sandbox.plaid.com/link/client/get 400 (Bad Request)
Error: Error retrieving info for public key. Make sure that the entered key is correct. Find your public key in your Dashboard (https://dashboard.plaid.com/account/keys).

The public keys are right—any ideas as to why that POST endpoint would be a bad request?

Is it not supposed to pop-up a selection interface where i can choose a bank? When i click on it, nothing happens. I have tried it on 3 different machines now.

Hey friends,

Setting up the Plaid client using Typescript 3.8.3, and using [email protected]. I've been following the Quickstart guide for node, and it sets up the plaid client with a clientApp setting:

When attempting to do the same, Typescript helpfully informs me that clientApp is not a a property of the ClientOptions type.

Is this a valid option, or is it just missing from the types?

Cheers!
Sean

This is related to iOS but I did not find the issue section there so I am writing details in this forum. I have integrated Plaid (version 1.1.28) from Cocoapods and facing this issue. I have checked on both iOS 12 and iOS 13 devices. I have verified the code in my app with the sample app and its exactly the same. I am sharing the screenshot of the button title when pressed.

Is there a way to bypass the web portal to list transactions through the CLI? Looking to automate this option without having to manually click the button. I'm using the python instance.

Hi folks,

The quickstart/go/server.go file on line 281 calls CreatePublicToken on the client
publicToken, err := client.CreatePublicToken(accessToken)

but the function is missing in the plaid-go package.

https://github.com/plaid/plaid-go/search?q=CreatePublicToken
is empty.

Possibly I am doing something wrong, but the python quickstart is not working for me. I freshly cloned it and then tried the following:

In one of the calls to /api/set_access_token from the Link Account page, an access_token parameter is sent instead of the expected public_token.

This may be do to my own ignorance but following the steps in the official repo lead to an environment error.

I know my credentials are loaded because printing them console before godotenv checks for a file prints the right info

There is also an issue with placing the client in the init function if I switch back to the old way variables were initialized.

Then still, if the plaid client is moved out of the init function and the env variables are left inside the init, I will get an API error saying.

Luckily for us, a co-worker had an old demo app that listed this feature... but now we are wondering, what else is missing from the doc?

For reference, the only mention of the selectAccount feature appears to be this comment...

      // user selected and the account ID or IDs, if the
      // Select Account view is enabled.

For Python 3, the output of base64.b64encode(asset_report_pdf) should be converted to str before attempting to jsonify.

I'm trying to use the Plaid Example Walkthrough but looks like the Link button is not working on python 3. Could be a compatibility problem?

Hi, this integration has been working fine until sometime last week/today. When using the Sandbox server, the 'user_good' 'pass_good' combination used to work fine, but now I'm receiving a page stating "Internal error Occured, we have been notified about the problem". The error message I am seeing in the console is: "the service responded with a status of 429 development.plaid.com/link/item/create".

This has been working fine on one of our app servers which we haven't changed code for in a while, so guessing it's a change on Plaid's side. Here's a reproducible example, where "index2.ejs" is similar to the given index.html:

# In app.py:
//Endpoint to reach Plaid Banking welcome screen
@app.route('/plaid/development/<string:customerId>')
def indexDevelopment(customerId):
  return render_template(
    'index2.ejs',
    plaid_public_key=PLAID_PUBLIC_KEY,
    plaid_environment="development",
    plaid_products=PLAID_PRODUCTS,
    plaid_country_codes=PLAID_COUNTRY_CODES,
    plaid_oauth_redirect_uri="http://localhost:5000/oauth-response2.html",
    plaid_oauth_nonce=PLAID_OAUTH_NONCE,
    customerId=customerId
  )

After walking through the steps provided at https://dashboard.plaid.com/overview/sandbox I am not able to select an institution. The steps I followed are specific to Ruby.

Steps taken:

1. git clone and cd into the directory
2. bundle install
3. copy and paste the keys provided on the page into the terminal
4. launch file with ruby app.rb
5. navigate to localhost:4567

First, thanks for providing this really useful resource...

Searching institutions gives me a "public key" error via console, but I have verified my public key is correct in the server.py file. Running python 3 and using Chrome. Thanks!

After running the ruby example app. I tried to call get Identity, but I got the following error:

Uncaught TypeError: Cannot read property 'names' of undefined

It happens with multiple banks (I tried 3-4 banks).
Nothing is shown under the section to send a request to get Identity. Nor a result neither an error.

In the java example, the html and css files refer to location from the root directory. eg: index.html has this in it "../../../../../html/index.html".

• Sign up for a free plaid developer account.
• git clone quickstart
• change client_id, secret, public_key and environment=development (python=>server.py, node=>set environment variables as explained on the instructions.
• Start either python or node application as indicated on the instructions.
• Attempt to connect to a bank
• I get the following message: Invalid key. The public key you provided was incorrect. Your public key is available from the Plaid dashboard.
• I get the following message on stdout when running the python application:

  Development is not intended for production usage.
                Swap out url for https://api.plaid.com
                via Client.config before switching to production

php?

Hi,

I am sending a post request to /institutions/get_by_id from browser,
Until now I was in sandbox environment where it was working fine,

But after deploying it to production, it throws me cors error

has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. 

Can this not work in production?
Should I send this request from my server instead of my client?

Getting error when trying to load Plaid JS.
Error: "invalid public_key provided. Request ID: sFgOMO4W1g8UBY1"

Please check and let me know what is the issue here. I have attached the Request ID for Reference.

I use nodejs quick start project, where I could logoin to any of the financial institutions and then could get few apis to accesss. I would like to transfer few usd to another account, how do I do that?

Hi, I am trying to implement Plaid example as a React Component class. I noticed your code is in the index.ejs file.

Is there a way to redo this to work as in a React Component class instead?

Below is my code which obviously isn't working.

import React from 'react';
import { Meteor } from 'meteor/meteor';
import Modal from 'react-modal';

export default class PlaidClient extends React.Component {

    constructor(props) {
        super(props);
        this.state = {
        };
    }

    makeRequest(){
        var handler = Plaid.create({
            apiVersion: 'v2',
            clientName: 'Plaid Walkthrough Demo',
            env: 'sandbox',
            product: ['transactions'],
            key: '24bca70c22bf0174f2b4e10bbe3932',
            onSuccess: function(public_token) {
              $.post('/get_access_token', {
                public_token: public_token
              }, function() {
                $('#container').fadeOut('fast', function() {
                  $('#intro').hide();
                  $('#app, #steps').fadeIn('slow');
                });
              });
            },
          });
    }

    onClick(e){
       //Not sure what to call here.
        
    }

    

    render(){
        return(
            <div id="container">
                <button className="button" onClick={this.onClick.bind(this)}>Connect your Credit Card(s)</button>
                <Modal>
                    
                </Modal>
            </div>
        );
    }

};

Hi @michaelckelly,

Does plaid allow you to limit the location for institutions to select from e.g. UK?

Also, can plaid limit these UK institutions that use Open Banking only to select from or how can this be done?

Thanks

The "Connect with Plaid" button is disabled by default. Why is that? What do I need to do for it to be enabled?

Hi,

I am running the quickstart on a Apple M1 without Docker. Following the instructions, this is what I received upon starting the frontend application. Any ideas?
