Overview preauth-overview

The Preauthorize API method is to be used by applications to obtain preauthorization decisions for one or more resources. The Preauthorize API request should be used for UI hints and/or content filtering. An actual Authorization API request must be made before allowing user access to the specified resources.

In case an unexpected error (for example, network issue, and MVPD authorization endpoint unavailable) takes place when a Preauthorize API request is processed by the Adobe Pass Authentication services, then one or multiple separate error information will be included for the affected resources as part of the Preauthorize API response result.

public preauthorize(request: PreauthorizeRequest, callback: AccessEnablerCallback<any>): void preauth-method

Description: This method is to be used by applications to obtain authenticated user’s preauthorization (informative) decisions from Adobe Pass Authentication service to view specific protected resources, for the primary purpose of decorating the application’s UI (e.g. indicating access status with lock and unlock icons).

Availability: v4.4.0+

Parameters:

  • PreauthorizeRequest: Builder Object used to define the request
  • AccessEnablerCallback: callback used to return the API response
  • PreauthorizeResponse: Object used to return the API response content

class PreauthorizeRequestBuilder preath-req-builder-class

setResources(resources: string[]): PreauthorizeRequestBuilder set-res-preath-req-buildr

  • Sets the List of resources for which you want to obtain preauthorization decisions.

  • It is mandatory to set it for the usage of preauthorize API.

  • Each element in the list must be a String representing either the resource ID value or the media RSS fragment which must be agreed with the MVPD.

  • This method sets the information only in the context of current PreauthorizeRequestBuilder object instance, which is the receiver of this method call.

  • To build an actual PreauthorizeRequest you can have a look at PreauthorizeRequestBuilder’s method:

  build(): PreauthorizeRequest
  • @param {string[]} resources. The List of resources for which you want to obtain preauthorization decisions.
  • @returns {PreauthorizeRequestBuilder} The reference to the same PreauthorizeRequestBuilder object instance, which is the receiver of the method call.
  • It does this to allow the creation of method chaining.

disableFeatures(…features: string[]): PreauthorizeRequestBuilder disabl-featres-preauth-req-buildr

  • Sets the features which you want to have them disabled when obtaining preauthorization decisions.
  • This function sets the information only in the context of current PreauthorizeRequestBuilder object instance, which is the receiver of this function call.
  • To build an actual PreauthorizeRequest you can have a look at PreauthorizeRequestBuilder’s function:
public func build() -> PreauthorizeRequest
  • @param {string[]} features. The set of features which you want to have them disabled.
  • @returns The reference to the same PreauthorizeRequestBuilder object instance, which is the receiver of the function call.
  • It does this in order to allow the creation of function chaining.

build(): PreauthorizeRequest preauth-req

  • Creates and retrieves the reference of a new PreauthorizeRequest object instance.
  • This method instantiates a new PreauthorizeRequest object every time it is called.
  • This method uses the values set in advance in the context of current PreauthorizeRequestBuilder object instance, which is the receiver of this method call.
  • Bear in mind that this method does not produce any side effects,
  • therefore it does not alter the state of the SDK or the state of the PreauthorizeRequestBuilder object instance, which is the receiver of this method call.
  • It means that successive calls of this method for the same receiver will create different new PreauthorizeRequest object instances, but having the same information, in case the values set to the PreauthorizeRequestBuilder where not modified between the calls.
  • In case you do not need to update any of the provided information (resources and caching) you may reuse the PreauthorizeRequest instance for multiple uses of the preauthorize API.
  • @returns {PreauthorizeRequest}

interface AccessEnablerCallback<T> interface-access-enablr-callback

onResponse(result: T); on-response-result

  • Response callback called by the SDK when the preauthorize API request was fulfilled.
  • The result is either a successful or an error result containing a status.
  • @param {T} result

onFailure(result: T); on-failure-result

  • Failure callback called by the SDK when the preauthorize API request could not be serviced.
  • The result is a failure result containing a status.
  • @param {T} result

class PreauthorizeResponse preauth-response-class

public status: Status; public-status

  • Returns: Additional status (state) information in case of failure.
  • Might hold a null value.

public decisions: Decision[]; public-decisions

  • Returns: The list of preauthorization decisions. One decision for each resource.
  • The list might be empty in case of failure.

class Status class-status

public status: number; public-status-numbr

  • The HTTP response status code as documented in RFC 7231.
  • Might be 0 in case the Status comes from the SDK instead of Adobe Pass Authentication services.

public code: number; public-code-numbr

  • The standard Adobe Pass Authentication services error code.
  • Might hold an empty string or a null value.

public message: string; public-msg-string

  • The detailed message which in some cases is provided by the MVPD authorization endpoints or by Programmer degradation rules.
  • Might hold an empty string or a null value.

public details: string; public-details-strng

  • Holds a detailed message which in some cases is provided by the MVPD authorization endpoints or by Programmer degradation rules.
  • Might hold an empty string or a null value.

public helpUrl: string; public-help-url-string

  • The URL that links to more information about why this state/error occurred and possible solutions.
  • Might hold an empty string or a null value.

public trace: string; public-trace-string

  • The unique identifier for this response, which can be used when contacting support to identify specific issues in more complex scenarios.
  • Might hold an empty string or a null value.

public action: string; public-action-string

  • The recommended action to remediate the situation.

    • none: Unfortunately there is no predefined action to remediate this issue. This might indicate an improper invocation of the public API
    • configuration: A configuration change is needed through TVE dashboard or by contacting support.
    • application-registration: The application must register itself again.
    • authentication: The user must authenticate or re-authenticate.
    • authorization: The user must obtain authorization for the specific resource.
    • degradation: Some form of degradation should be applied.
    • retry: Retrying the request might solve the issue
    • retry-after: Retrying the request after the indicated period of time might solve the issue.

  • Might hold an empty string or a null value.

class Decision class-decision

public id: string; public-id-string

  • The resource id for which the decision was obtained.

public authorized: boolean; public-auth-boolean

  • The value of the flag indicating if the decision is successful or not.

public error: Status; public-error-status

  • Additional status (state) information in case some error has occurred. Might hold a null value.

Client implementation example client-imp-example


let accessEnablerApi = new window.AccessEnabler.AccessEnabler("software statement");
let accessEnablerModels = window.AccessEnabler.models;



// Build request
let requestBuilder = new accessEnablerModels.PreauthorizeRequest.getBuilder();
let request = requestBuilder
    .setResources(["RES01", "RES02", "RES03"])
    .disableFeatures("LOCAL_CACHE")
    .build();



// Create callback
let callback = {
    onResponse(response) {
        // Handle onResponse
    },
    onFailure(response) {
        // Handle onFailure
    }
};

// Invoke call
accessEnablerApi.preauthorize(request, callback);
