Getting a token, 2. Using Access Tokens

A web app that calls web APIs: Acquire a token for the app

All of the information below follows standard OAuth2 protocols. Prerequisites: An existing Panopto OAuth2 client and its credentials. Getting an Access Token 1. Getting a token usually involves redirecting a user in a web browser to the Panopto sign-in page, then redirecting the response back to the redirect URL and retrieving the token provided. Some of the methods to get an access token will require authenticating your client credentials.

Token Based Authentication

To authenticate the client credentials, the client API key and client secret value are sent as part of the token request in the Authorization header. This uses the Basic authorization method. The value to send is created as follows: 1. Then, Base64 encode the result.

All requests should at least request openid and api scopes. The user will be redirected here after the sign in process.

Get Access Tokens

This must exactly match one of the redirect URLs added to the client, including any parameters. This can be randomly generated and should be included in the response token for validation. This is not needed and can be ignored. Once you have the code, you can exchange it for a token.

Do not include any of the query parameters passed back. See 1.

Token Based Authentication Made Easy

This can be used to verify that the token comes from the correct server, was not reissued, and to get some additional user information. This token is not needed for API access or for getting user information.

After this time period, the token will no longer be valid, and a new one must be retrieved. This should be kept confidential. If the request is not successful, then the JSON object returned will only contain a single field: error: A string describing the error type.

In addition, authorization codes expire within 5 minutes, so they should be used immediately.

Since these clients cannot be trusted to keep their client secret safe, a code challenge and verifier are used to authenticate that the request for a code and token come from the same client.

Welcome to Panopto Support

The client should create a code verifier string. This should be created for each request. A code verifier string is a random string between 43 and characters long that is made up of characters from the following set letters, numbers, or the hyphen, period, underscore, and getting a token characters : A-Za-z This is also used to generate the code challenge.

The code challenge is sent as part of the request for an authorization code, and the code verifier is sent as part of the request to convert an getting a token code to an access token. The code challenge is generated by first Base64 encoding the code verifier, then hashing the result getting a token SHA This should be the original generated string, and should not be hashed.

Although the client secret is not considered to be part of the authentication when using this flow, it is still required to be sent. Note: Each code can only be used once, and if the POST request is denied, then the code will be invalidated and a new code must be retrieved from the OAuth2 service.

Step 1: Get Authorization

If the access token is valid, then the request should process as normal. Getting a token the request fails with an HTTP Status ofthen the access token has likely expired or been invalidated. If you have a refresh token, you can use it to get a new access token. Otherwise, follow the full workflow in section 1 to get a new token depending on the client type.
