It also configures the OPTIONS method's 200 response with the required Access-Control-Allow-* headers. Note: Configuring CORS in the API Gateway console adds an OPTIONS method to the resource if one doesn’t already exist. Also, choose the check boxes for all of the other methods that are available to CORS requests. For Methods, choose the check box for the OPTIONS method, if it isn't already selected.For example, if a request includes an incorrect resource path, API Gateway still responds with a 403 "Missing Authentication Token" error. Note: When you select these default options, API Gateway responds with the required CORS headers, even when a request doesn't reach the endpoint.

For Gateway Responses for API, choose the DEFAULT 4XX and DEFAULT 5XX check boxes.

While configuring CORS on your API resource, make sure that you do the following: For a CORS request, API Gateway adds the configured CORS headers to the response from an integration. This response is sent even if there isn't an OPTIONS route configured for your API. Important: If you configure CORS for an HTTP API, then API Gateway automatically sends a response to preflight OPTIONS requests.

Use the developer tools in your browser to check the request and response parameters from the failed API request.Ĭonfigure CORS on your API resource that’s experiencing the errorįollow the instructions to Turn on CORS on a resource using the API Gateway console.įollow the instructions in Configuring CORS for an HTTP API.

Then, confirm the cause of the error in the file by checking the headers in the parameters returned in the API response.

Create an HTTP Archive (HAR) file when you invoke your API.

There are two ways to confirm the cause of a CORS error from API Gateway:

(For private REST APIs only) The incorrect invoke URL is called, or the traffic isn't being routed to the interface virtual private cloud (VPC) endpoint.

An API with proxy integration or non-proxy integration isn't configured to return the required CORS headers.

Another method type (such as GET, PUT, or POST) isn't configured to return the required CORS headers.

The API isn't configured with an OPTIONS method that returns the required CORS headers.

Note: The No 'Access-Control-Allow-Origin' header present error can occur for any of the following reasons: For example: Method not supported under Access-Control-Allow-Methods header errors and No ‘Access-Control-Allow-Headers’ headers present errors. However, you can use a similar procedure to troubleshoot all CORS errors.

The following example procedure shows how to troubleshoot the No ‘Access-Control-Allow-Origin’ header present CORS error. Note: CORS must be configured at the resource level and can be handled using API Gateway configurations or backend integrations, such as AWS Lambda.

For HTTP APIs, see Configuring CORS for an HTTP API. To resolve a CORS error from an API Gateway REST API or HTTP API, you must reconfigure the API to meet the CORS standard.įor more information on configuring CORS for REST APIs, see Turning on CORS for a REST API resource.

Typically, you should place these kinds of routes outside of the web middleware group that the App\Providers\RouteServiceProvider applies to all routes in the routes/web.php file.Cross-Origin Resource Sharing (CORS) errors occur when a server doesn’t return the HTTP headers required by the CORS standard. For example, if you are using Stripe to process payments and are utilizing their webhook system, you will need to exclude your Stripe webhook handler route from CSRF protection since Stripe will not know what CSRF token to send to your routes. Sometimes you may wish to exclude a set of URIs from CSRF protection. If you are building a SPA that is utilizing Laravel as an API backend, you should consult the Laravel Sanctum documentation for information on authenticating with your API and protecting against CSRF vulnerabilities. When these two tokens match, we know that the authenticated user is the one initiating the request. The App\Http\Middleware\Verif圜srfToken middleware, which is included in the web middleware group by default, will automatically verify that the token in the request input matches the token stored in the session.
