      description: "# Using DAIS for M2M/API Auth\nYou have been given a Client ID and a Client Secret, which are used to request a DTN Access Token. DTN Access Tokens are required when making calls to each and every DTN API endpoint. The following information provides additional details on these tokens and how they are generated.\n## What is an Access Token and how is it different from an API Key?\nAn API Key is a random string of characters that an API uses to authorize whether or not a calling client has approved access to an endpoint. These keys are a non-standard approach to API authorization and are generally issued on a per-API basis.\n\nAn Access Token is also a string of characters but is a base-64 encoded JavaScript Object Notation Web Token, or JWT. JWTs are a widely accepted standard that use OAuth concepts and approaches. \n\nBoth API Keys and Access Tokens are used in an Authorization Request Header as a Bearer, meaning there is no difference in where you put this string of characters when you make calls to DTN APIs.\n## How to generate an Access Token?\nWhen requested, an Access Token is generated for your specific Client (ID/Secret) and for a specific API. The DTN Auth and Identity Service (DAIS) generates new Access Tokens for your client. The DAIS endpoint is `POST https://api.auth.dtn.com/v1/tokens/authorize`.\n\nThis endpoint takes two Header parameters:\n  * `Content-Type: application/json`\n  * `Accept: application/json`\n\nThis endpoint takes four parameters in the Request Body:\n  * `grant_type`: this should always be client_credentials for generating machine-to-machine tokens.\n  * `client_id`: this is the Client ID or Application ID using the token and is given to you by DTN's Identity Team. This ID will never change for your client/application.\n  * `client_secret`: this is the Client Secret that is associated with the Application ID and is given to you by DTN's Identity Team. This key is subject to rotation for security purposes but always with the client's knowledge.\n  * `audience`: this is the API for which this Access Token will be used. For the DTN Websocket API, you need to use the following audience: https://dev-portal.dev.coreservices.zones.dtn.com\n\nYou can use this CURL command template as a reference for obtaining an access token:\n  ```\n  curl --location --request POST 'https://api.auth.dtn.com/v1/tokens/authorize' \\\n--header 'Accept: application/json' \\\n--header 'Content-Type: application/json' \\\n--data-raw '{\n\"grant_type\": \"client_credentials\",\n\"client_id\": \"insert your client id here\",\n\"client_secret\": \"insert your client secret here\",\n\"audience\": \"insert your audience here\"\n}' \n  ```\n\n*This document, for demonstration purposes, supplies a client_id and client_secret in all code examples. This client/application is for a fictitious API and cannot be used in practice to gain unauthorized access to any other DTN API.*\nUpon generating a new Access Token, you should receive an HTTP Response from DAIS similar to this:\n  ```\n  {\n    \"data\": {\n          \"access_token\": \"eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6InpfX21pZW13NGhoTmdvQWQxR3N6ciJ9.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.0VHdyp1w9PPFVI0FPheAwuKZwb5C25rwP-LPMXcSNoRmouvga1DZtNLA67ZzE_sAlc_VpaDRr6daLKr_Alw4347mw9sdjP8wKR27kCZa9JZK5PGQMmXHscATbzBEJYpCPklfyGaajgymqTBGnedcv8F0UvlRzQPsFeRPnVoX7BWOSXpMbyToGiXWkQLBQT7r96KAmLZOPJFZspPtjw-wH2mSL2WNa_nkB4j5vMGhGxlKiNRsKb30TH_WAel2hsxNlcPK3XHCmrMTYsNnu7HNqOTMn2i0__0rvBrhSWEw-_grqQDmWFJuWd7Qhi1q81AaJcdqgoSa_efz93QFclJUNw\",\n          \"scope\": \"read:demo create:demo update:demo\",\n          \"expires_in\": 90,\n          \"token_type\": \"Bearer\"\n      },\n      \"meta\": {\n          \"date_time\": \"2022-06-24T19:09:42.963Z\",\n          \"name\": \"v1.tokens.authorize\",\n          \"uuid\": \"ee6f9feb-dcf8-4421-a6fd-efd6beabdaa9\",\n          \"start_timestamp\": 1656097782509,\n          \"end_timestamp\": 1656097782963,\n          \"execution_time\": 454\n      }\n  }\n  ```\nLooking at this Response, you will see:\n  * `access_token`: contains the JWT Access Token string you will use as your Bearer token.\n  * `scope`: contains the scopes that this Access Token gives you permissions to access.\n  * `expires_in`: contains the length of time before this Access Token will expire, in seconds.\n  * `token_type`: verifies that this Access Token should be used as a Bearer token.\n\n## How to use an Access Token after one is generated?\nOnce a new Access Token is obtained, it is used in each call to a DTN API endpoint as a Bearer token in an Authorization Request Header.
