   "description":"Open Channel enables your system to exchange messages with Infobip SaaS products through the Infobip public API.\n\nInbound messages are sent through the Infobip API to the Open Channel destination that is registered on the Infobip platform. The messages are sent to a SaaS product, like a chatbot. Outbound responses from a SaaS product are sent by the Infobip platform to your API webhook that is registered for a specific Open Channel sender.\n\nThis feature is in the Early Access stage. Contact your Infobip account manager to configure the Open Channel sender and the webhook for receiving the response. Currently, Open Channel is available for Answers and Conversations. In the future, Open Channel will be available for other Infobip SaaS products like Moments.\n",

Furthermore, API keys can have a limited scope and cover only some API methods. Lastly, they can\nbe revoked at any time. This range of possibilities makes API keys well suited for separating the API access rights across multiple applications or use cases.\nFinally, the loss of an API key is easily manageable.\n\nYou can manage your API keys from [GUI](https://portal.infobip.com/settings/accounts/api-keys), or programmatically\nwith [dedicated API](#platform-&-connectivity/settings).\n\nAPI key Authorization header example:\n\n```shell\nAuthorization: App 003026bbc133714df1834b8638bb496e-8f4b3d9a-e931-478d-a994-28a725159ab9\n```\n",

For example, API methods for generating API keys should be authenticated\nwith the Basic type.\n\nIn this case, the credentials included in the Authorization header should be a Base64 encoded username and password combination. More formally, basic\nauthentication header can be constructed in three steps:\n\n* Username and password are concatenated using the colon `(:)` as a separator `username:password`.\n* The resulting string is encoded using the [RFC2045-MIME](https://www.ietf.org/rfc/rfc2045.txt) variant of Base64.\n* Encoded string is added as credentials after the `\"Basic \"` type.\n\nExample:\n\n```shell\nUsername: \"Aladdin\"\nPassword: \"openSesame\"\n\nConcatenated string: \"Aladdin:openSesame\"\n\nBase64 encoded string: \"QWxhZGRpbjpvcGVuU2VzYW1l\"\n\nAuthorization header: \"Basic QWxhZGRpbjpvcGVuU2VzYW1l\"\n```\n\n> **Implementation detail**: Base64 encoding is a standard and many available programming languages and frameworks provide convenient methods for encoding\n> strings.\n",

Note that the session will expire automatically after a predefined period of inactivity, and can also be manually\nterminated by making an appropriate API call.\n\nYou can find more details on the creation and behavior of the session at\nthe [dedicated documentation page](#platform-connectivity/account-management/create-session).\n\nAfter obtaining the session token by calling the above-referenced API method you can include it in the Authorization header like this:\n\n```shell\nAuthorization: IBSSO 2f9b4d31-2d0d-49a8-85f0-9b862bdca394\n```\n",

You can find out more about the process in\nthe [official specification](https://tools.ietf.org/html/rfc6749#section-4.4).\n\nYou can include your access token in the Authorization HTTP request header like this:\n\n```http\nAuthorization: Bearer <access_token>\n```",
