HEADER SET ACCESS CONTROL ALLOW ORIGIN HOW TO

Access-Control-Allow-Origin with the same value as Origin in the request.It expects that the HTTP response contains the following headers: The URL also always has a query string with the _amp_source_origin parameter set to the email address of the sender of the email. Origin with the value of the origin of the page used to display the email.It also provides an Origin header and requires the Access-Control-Allow-Origin header in response, like CORS on websites.

In version 1, the email client uses a query string parameter instead of an HTTP header to indicate the sender email. The email client sends an HTTP request to with the following headers set:ĪMP-Email-Allow-Sender: using * in either header is allowed (but not recommended). The email uses AMP for Email and loads data using an amp-list from.

AMP-Email-Allow-Sender with either the same value as AMP-Email-Sender in the request, or * indicating all sender emails are allowed.Ī user opens an email from in their email client by going to.

It expects that the HTTP response contains the following header in return:

AMP-Email-Sender, set to the email address of the sender of the email.

When an email makes a request via amp-form, amp-list or any other XHR-based mechanism, the email client includes the following HTTP header: For the time being, it's recommended to support both on your server-side. There are currently two versions of this mechanism. AMP for Email extends this mechanism by adding HTTP headers that similarly tell email clients which senders are allowed access to these resources. Your Okta user profile appears below the form.Important: this documentation is not applicable to your currently selected format websites!Ĭross-Origin Resource Sharing (CORS) is a mechanism that uses HTTP headers to tell browsers which origins are allowed access to a resource using XHR. In the same browser in which you have an active session in your Okta organization, enter your Okta subdomain in the form below and click Test.Test your configurationĭo the following to test your CORS configuration: Note: If you don't enable CORS, or disable it at a later date, the list of websites is retained. You can also enable the Redirect setting, which allows for redirection to this Trusted Origin after a user signs in or out. Make sure that CORS is selected as the Type.In the Origin URL box, specify the base URL of the website that you want to allow cross-origin requests from.Select Add Origin and then enter a name for the organization origin.You can enable CORS for websites that need cross-origin requests to the Okta API. Note: IE8 and IE9 don't support authenticated requests and can't use the Okta session cookie with CORS. You can review which browsers support CORS on /cors (opens new window)

APIs that support CORS are marked with the following icon CORS. If you're building an application that needs CORS, check that the specific operation supports CORS for your use case. The Okta API supports CORS on an API by API basis. See Scopes and supported endpoints.Ĭaution: You should only grant access to specific origins (websites) that you control and trust to access the Okta API. If you are using OAuth 2.0 tokens to make calls to Okta APIs, you don't need to add a Trusted Origin because OAuth for Okta APIs don't rely on cookies. Every website origin must be explicitly permitted as a Trusted Origin. In Okta, CORS allows JavaScript hosted on your websites to make a request using XMLHttpRequest to the Okta API with the Okta session cookie. CORS defines a standardized (opens new window) way in which the browser and the server can interact to determine whether or not to allow the cross-origin request. Such cross-domain requests would otherwise be forbidden by web browsers as indicated by the same origin security policy (opens new window).

Grant cross-origin access to the Okta API from your web apps.Ĭross-Origin Resource Sharing (CORS) (opens new window) is a mechanism that allows a web page to make an AJAX call using XMLHttpRequest (XHR) (opens new window) to a domain that is different than the domain where the script was loaded.
