API for Amazon Interactive Video Service Chat¶

ABAP Package	`/AWS1/API_IVC_IMPL`
ABAP SDK "TLA"	`IVC`
ABAP Interface	`/AWS1/IF_IVC`

The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for Amazon Interactive Video Service Chat is IVC. This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.

Installation¶

To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the ivschat module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.

About The Service¶

Introduction

The Amazon IVS Chat control-plane API enables you to create and manage Amazon IVS Chat resources. You also need to integrate with the Amazon IVS Chat Messaging API, to enable users to interact with chat rooms in real time.

The API is an AWS regional service. For a list of supported regions and Amazon IVS Chat HTTPS service endpoints, see the Amazon IVS Chat information on the Amazon IVS page in the AWS General Reference.

This document describes HTTP operations. There is a separate messaging API for managing Chat resources; see the Amazon IVS Chat Messaging API Reference.

Notes on terminology:

You create service applications using the Amazon IVS Chat API. We refer to these as applications.
You create front-end client applications (browser and Android/iOS apps) using the Amazon IVS Chat Messaging API. We refer to these as clients.

Resources

The following resources are part of Amazon IVS Chat:

LoggingConfiguration — A configuration that allows customers to store and record sent messages in a chat room. See the Logging Configuration endpoints for more information.
Room — The central Amazon IVS Chat resource through which clients connect to and exchange chat messages. See the Room endpoints for more information.

Tagging

A tag is a metadata label that you assign to an AWS resource. A tag comprises a key and a value, both set by you. For example, you might set a tag as topic:nature to label a particular video category. See Best practices and strategies in Tagging Amazon Web Services Resources and Tag Editor for details, including restrictions that apply to tags and "Tag naming limits and requirements"; Amazon IVS Chat has no service-specific constraints beyond what is documented there.

Tags can help you identify and organize your AWS resources. For example, you can use the same tag for different resources to indicate that they are related. You can also use tags to manage access (see Access Tags).

The Amazon IVS Chat API has these tag-related operations: TagResource, UntagResource, and ListTagsForResource. The following resource supports tagging: Room.

At most 50 tags can be applied to a resource.

API Access Security

Your Amazon IVS Chat applications (service applications and clients) must be authenticated and authorized to access Amazon IVS Chat resources. Note the differences between these concepts:

Authentication is about verifying identity. Requests to the Amazon IVS Chat API must be signed to verify your identity.
Authorization is about granting permissions. Your IAM roles need to have permissions for Amazon IVS Chat API requests.

Users (viewers) connect to a room using secure access tokens that you create using the CreateChatToken operation through the AWS SDK. You call CreateChatToken for every user’s chat session, passing identity and authorization information about the user.

Signing API Requests

HTTP API requests must be signed with an AWS SigV4 signature using your AWS security credentials. The AWS Command Line Interface (CLI) and the AWS SDKs take care of signing the underlying API calls for you. However, if your application calls the Amazon IVS Chat HTTP API directly, it’s your responsibility to sign the requests.

You generate a signature using valid AWS credentials for an IAM role that has permission to perform the requested action. For example, DeleteMessage requests must be made using an IAM role that has the ivschat:DeleteMessage permission.

For more information:

Authentication and generating signatures — See Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon Web Services General Reference.
Managing Amazon IVS permissions — See Identity and Access Management on the Security page of the Amazon IVS User Guide.

Amazon Resource Names (ARNs)

ARNs uniquely identify AWS resources. An ARN is required when you need to specify a resource unambiguously across all of AWS, such as in IAM policies and API calls. For more information, see Amazon Resource Names in the AWS General Reference.

Using the SDK¶

In your code, create a client using the SDK module for Amazon Interactive Video Service Chat, which is created with factory method /AWS1/CL_IVC_FACTORY=>create(). In this example we will assume you have configured an SDK profile in transaction /AWS1/IMG called ZFINANCE.

DATA(go_session)   = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ).
DATA(go_ivc)       = /aws1/cl_ivc_factory=>create( go_session ).

Your variable go_ivc is an instance of /AWS1/IF_IVC, and all of the operations in the Amazon Interactive Video Service Chat service are accessed by calling methods in /AWS1/IF_IVC.

API Operations¶

For an overview of ABAP method calls corresponding to API operations in Amazon Interactive Video Service Chat, see the Operation List.

Factory Method¶

`/AWS1/CL_IVC_FACTORY=>create( )`¶

Creates an object of type /AWS1/IF_IVC.

IMPORTING¶

Optional arguments:¶

`IV_PROTOCOL` `TYPE /AWS1/RT_PROTOCOL` `/AWS1/RT_PROTOCOL`¶

`IO_SESSION` `TYPE REF TO /AWS1/CL_RT_SESSION_BASE` `/AWS1/CL_RT_SESSION_BASE`¶

`IV_REGION` `TYPE /AWS1/RT_REGION_ID` `/AWS1/RT_REGION_ID`¶

`IV_CUSTOM_ENDPOINT` `TYPE /AWS1/RT_ENDPOINT` `/AWS1/RT_ENDPOINT`¶

RETURNING¶

`OO_CLIENT` `TYPE REF TO /AWS1/IF_IVC` `/AWS1/IF_IVC`¶

/AWS1/IF_IVC represents the ABAP client for the ivschat service, representing each operation as a method call. For more information see the API Page page.

Configuring Programmatically¶

DATA(lo_config) = DATA(go_ivc)->get_config( ).

lo_config is a variable of type /AWS1/CL_IVC_CONFIG. See the documentation for /AWS1/CL_IVC_CONFIG for details on the settings that can be configured.

Paginators¶

Paginators for Amazon Interactive Video Service Chat can be created via get_paginator() which returns a paginator object of type /AWS1/IF_IVC_PAGINATOR. The operation method that is being paginated is called using the paginator object, which accepts any necessary parameters to provide to the underlying API operation. This returns an iterator object which can be used to iterate over paginated results using has_next() and get_next() methods.

Details about the paginator methods available for service Amazon Interactive Video Service Chat can be found in interface /AWS1/IF_IVC_PAGINATOR.
