I'm doing a test locally and whenever I hit the button from the example I found on Custom Integration I'm getting this error:
XMLHttpRequest cannot load https://link-tartan.plaid.com/client/info. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://cdn.plaid.com' is therefore not allowed access. The response had HTTP status code 403.
I've read that the server needs to add a header to the response with
Access-Control-Allow-Origin: *
However the problem is the server isn't owned by me and I'm just requesting response from an API from Plaid.
What are the options that I have that I can do and fix on my end?
I got a response from Plaid support. And it turned out they only support certain IP addresses. So I ask them to allow my IP address to transact to their API. Other solution would be to use a VPN, hope this helps.

I am trying to build a little website where i need to use Docxtemplater. (https://docxtemplater.com/)
This is a node module used to edit word documents (.docx). In the docs (https://docxtemplater.com/docs/generate/), it is stated "Please note that if you want to load a docx from your filesystem, you will need a webserver or you will be blocked by CORS policy."
I have tried uploading my website to a host (https://www.000webhost.com/), but i get the error:
mathiastester.000webhostapp.com/:1 Access to XMLHttpRequest at 'https://docxtemplater.com/tag-example.docx' from origin 'https://mathiastester.000webhostapp.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Does anyone have any clue on what is going on...?
Here is the website: https://mathiastester.000webhostapp.com/
Just like the example in the link you provided, your AJAX code needs to make a request to some server-side code running on your webserver, which then sends the request to docxtemplater, because docxtemplater doesn't allow cross-origin ("CORS") requests to it.
Simply put, a CORS request is an AJAX request where the request is sent to a different "origin" (combination of domain, port and protocol) than the one it is running from. These are disallowed by browsers by default for security reasons, but the remote server can, if it wishes, return response headers indicating to the browser that the request can in fact be allowed. docxtemplater doesn't do that, and the documentation you quoted is telling you not to make a CORS request to their servers. However judging by the error message you've shown us, you've done exactly that in your code.
See https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS for more info on what CORS is.
I have shopify admin api and I want to call it in the front end but when i try to fetch the data it gives me the following error "Access to XMLHttpRequest at 'https://API_KEY:PASSORD#NAME.myshopify.com/admin/api/2021-07/orders.json' from origin 'null' 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.", I use axios and fetch and both did not work.
any help well be appreciated.
Great question! It's one that I have encountered as well. Shopify purposely blocks CORS requests. In order to make requests to your backend you will need to setup a Shopify APP Proxy for your front-end to communicate with.
Essentially what this does, is it permits your front-end to make requests to app/api/v1/orders_endpoint which Shopify will then route to https://yourapp.com/api/v1/orders_endpoints.
Check out the Shopify documentation for more information. The code to verify the signature is in Ruby, but some quick google foo turns up results in Javascript as well, see this stack overlow post.
guys!
I'm having some trouble with javascript in Ionic. I'm trying to make a request to another site, and I'm having this error message:
XMLHttpRequest cannot load https://svcs.sandbox.paypal.com/AdaptivePayments/Pay. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.
My Ionic App have already the plugin whitelist installed and up to date, my config.xml file allow navigation and access of every location. I've tried also to execute chrome with security disabled and it didn't work either.
Could anyone help? Don't know what else to do.
By default, XMLHttpRequests are limited to same domain requests (i.e. request between localhost and localhost or request between paypal.com and paypal.com).
Cross-site XMLHttpRequests (like from localhost to paypal.com) are disabled by default as a security feature in modern browsers, in order to bypass this security feature, the destination server should explicitly allow cross-site requests and this is done by sending back a header called "Access-Control-Allow-Origin" with either * or specific domain as value, for example when a server replies back with the following header:
Access-Control-Allow-Origin: *
It is telling the browser of visitor that I'm accepting an XMLHttpRequest from any domain.
In your case, you are doing a request on https://svcs.sandbox.paypal.com/AdaptivePayments/Pay which doesn't allow cross-site requests (no Access-Control-Allow-Origin is present) and thus the browser is blocking XMLHttpRequest from going through.
You cannot test your http://localhost:8100 (LOCALHOST) to paypal services/api's that requires communication with your script, except if you use tunnel hosts, like https://ngrok.com/, https://localtunnel.me/. Your scripts that run in your localhost should be accessible to the world wide web, so that it is visible to Paypal.
I am implementing oauth for pinterest and able to get the access code, but when I am trying to do a GET /v1/me/ I am getting this error in chrome console -
XMLHttpRequest cannot load
https://api.pinterest.com/v1/me?oauth_token=XXXXX&v=20121125. No
'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'https://localhost:3000' is therefore not allowed
access.
In general I know its related to headers setting in server end for enabling CORS, but I want to know specifically how can I make it working for pinterest.
Seems like you have not whitelisted your URL (https://localhost:3000) in the pinterest developers section where it asks you to specify redirect url.
Hope this helps!
Try jsonp method to do a cors request in angualrjs.
$http.jsonp('https://api.pinterest.com/v1/me?oauth_token=XXXXX&v=20121125&callback=JSON_CALLBACK')
How can I call the Power BI API from my application and understand Microsoft APIs?
I have successfully authorized users via the Azure AD library for JavaScript. However I have not been able to get a successful response from the API in the console. I get an unauthorized error, no access control allow origin header is present on the requested resource.
I am used to making API calls using Javascript and Angular, but not with Microsoft APIs and how they must be authorized. I have tried to read articles but they go over my head.
The errors are as follows
Failed to load resource: the server responded with a status of 404 (Not Found)
XMLHttpRequest: cannot load https://api.powerbi.com/v1.0/myorg/dashboards. Response to preflight request doesn't pass access control check: No Access-Control-Allow-Origin header is present on the requested resource. Origin http://renniesb.github.io is therefore not allowed access. The response had HTTP status code 404.
nope
Repository with my project code
https://github.com/Renniesb/sample_dashboard/tree/gh-pages
Place in repository that shows my Power B.I API call https://github.com/Renniesb/sample_dashboard/blob/gh-pages/app/services/powerbi.service.js
Expected behavior
List dashboards in the console.
Test site
https://Renniesb.github.io/sample_dashboard. To test I authorize with my credentials. How would I let users of this forum test the behavior. How do I enable their credentials?
List of things I've tried already
Created a reverse proxy using the following website: http://shawnsimondeveloper.com/nodeproxyangular/
Used the JSONP hack to attempt to get around CORS problem.
Put in the origin of the call in the webconfig file.
Tested the site both locally and on a webpage on GitHub
You shouldn't need to use both CORS and the HTTP proxy. Since you are using the ADAL JS library it will automatically append your Power BI token to your outgoing HTTP requests.
You will also need to setup the following:
Enable implicit grant flow as described in Step 3
Also, the dashboards endpoint is still only available in the "beta" version. This was causing the 404's.
Update your URLs to https://api.powerbi.com/beta/myorg/dashboards
To continue to use standard AJAX call with CORS:
Update your Angular powerbiService service to make HTTP requests directly to the https://api.powerbi.com domain rather than relative urls.
