With this tutorial I want to guide you how to control your Alexa (Amazon Echo or Amazon DOT) via command line (cURL tool).
To remote control your Alexa you need to extract some authentication credentials from a Browser session. Therefore you have to use Google Chrome and open https://alexa.amazon.com When you are logged in to the Webservice select "Music and Books" Then select the correct Alexa you want to manage on the top menu And finally select the "TuneIn" icon.
Then search for the Radio station you are looking for and start the station. Next step is to open in Chrome the developer tools.
The Chrome menu, Tools > Developer Tools. Ctrl+Shift+I on Windows. Cmd+Opt+I on Mac.
Now select the "Network Tab" (1) and clear to clear the cache (2). Then select the radio station you want to listen (3). Now you should find in the network tab a line starting with "queue-and-play" (4). Now you can rightclick the line => copy => copy as cURL

Now you can find all the important credentials for authentication: DEVICENUMBER = "G999LF0964210K58" (SerialNumber) DEVICETYPE = "A3S5BHHHU6VAYF" CUSTOMERID = "A2C7IGOABH59PS" CSRF = "-2012345694" (please copy the complete csrf with leading sign) COOKIE = "Cookie: x-amzn-<.......>.aA="; csrf=-2012345694" (the whole very long string!)
guideId = "s133505" - this is the parameter for the selected radio station on TuneIn - will be required as parameter
Example cURL from Clipboard (this is just scrambled demo data - use your own!): curl 'https://pitangui.amazon.com/api/tunein/queue-and-play?deviceSerialNumber=G999LF0964210K58&deviceType=A3S5BHHHU6VAYF&guideId=s133505&contentType=station&callSign=&mediaOwnerCustomerId=A2C7IGOABH59PS' -X POST -H 'Origin: http://alexa.amazon.com' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: en' -H 'User-Agent: Mozilla/5.0 (iPad; CPU OS 9_1 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13B143 Safari/601.1' -H 'Content-Type: application/json; charset=UTF-8' -H 'Accept: application/json, text/javascript, /; q=0.01' -H 'Referer: http://alexa.amazon.com/spa/index.html' -H 'csrf: -2012345694' -H 'Cookie: x-amzn-dat-gui-client-v=1.24.986.0; aws-target-static-id=14712345678-839972; aws-session-id=168-0412369-4130549; aws-session-id-time=2106194071l; aws-x-main=PgpqvER9Wibauhf4zfSDriNBlBILfMnk; aws-at-main=Atza|IwEBIAFsntUWFc_PZvFde5drDzPNXXXXXXXXXHPqI53aQNl-Fu83eAMUsFJmMtamv_4mLKEh6N82lqq8OHA8SKgh44X2MZwTguXNcUvd0-RVQyayT2lQ86JjoXvJrlMlrZIs7kJLWBryCGJEXXXXXXXXXXFJQpHhnGeC72ljNT_nVObL_wZoYhMFHVMXGiYjFyrb-QcjYY-I3ar-Q-kLAmzZYQIKU-mZ8GChNefKuG_x4ZZ2A06XXXXXXXXXOhX9w94vgmn2y3Qr9Q0rEi8K--UoFuTQ54GArubNsofNLh4U2dov8D7Gs3GoW6Hp2zEwt7cyumpRR_vceAz3aUjskoNKXsgDfpPZrebl-0R4bC6BfIasyoDOX9XXXXXXXXjRihKSxf4gs79p1ExYBmaBOX6glBrsKRqOXfk6Vh87_96uQ; aws-userInfo=%7B%22arn%22%3A%22arn%3Aaws%3Aiam%3A%3A314911114493%3Aroot%22%2C%22alias%22%3A%22%22%2C%22username%22%3A%22MeinUser%2520Name%22%2C%22keybase%22%3A%22dhVv%2Fmb%2BJyCH%2BJA6zwfighlgs5jc0W0mVYXkLBkb77M%5Cu003d%22%2C%22issuer%22%3A%22https%3A%2F%2Fwww.amazon.com%2Fap%2Fsignin%22%7D; __utmv=191231197.PgpqvER9Wibauhf4zfSDXXXXXXXXk; s_dslv=1475471239073; regStatus=registered; aws-target-visitor-id=1475445653051-715340.26_4; aws-target-data=%7B%22support%22%3A%221%22%7D; s_pers=%20s_ev15%3D%255B%255B%2527Typed%252FBookmarked%2527%252C%25212375474893114%2527%255D%255D%7C1632141293114%3B%20s_fid%3D0523A63XXXXXXXXX3C9679E640DA3570%7C1538547024210%3B%20s_dl%3D1%7C1475481765932%3B%20gpv_page%3Dno%2520value%7C1475481765939%3B; session-id=151-3512347-8293901; session-id-time=2106212731l; s_fid=71689F1234D6D238-299FD69294EFC3C1; s_nr=1475492764173-Repeat; aws-ubid-main=151-3388123-1263140; aws-session-token="lprp9YroXXXXXXXXXz5EFfSaPt96R0oSBWL2dR/AGFdlmk4QwRcVPXXXXXXXrmZ5kfHBdNwvSWWMKTnYU0pB5CE2XXXXXXUk6SIuaQYti17ZQ8B3NGwyCKNs7Lil+kz9qonZS5/cwtmrWHCe7SGx/QmPXXXXXXX89WbiV2xwTRkhVw6hTjO+8WUOXXXXXXXXi8MaR196v+Ewflx7dd3ouTVtY+hbJE4XSs="; __utma=194891197.1975555581.1444474071.1475495555.1475555580.5; __utmz=194555597.1475555680.5.2.utmccn=(referral)|utmcsr=console.aws.amazon.com|utmcct=/cloudwatch/home|utmcmd=referral; ubid-main=152-8362434-2710144; session-token="Y2Eoqs81+wIbanI7mPonK9t7gFvH7ZdTG2OxCZB3orqTILNY5ev4cFBWiSPTl2u8nFNXNmwtFP6RxnPBTunkdbHfpos8WYYOX7gEF52wnn5J3SknsvO99+MAT5GeyMR4JRa+ZOX+DcnIt8xtgYY2sSaEZ3JspjrQF+M9PUkuT9D4aYbZGRNa1BkFvoOt8Kettr9xxS/ODPfXEaE6xJr7qyPv0IQ3K6e+FbfGk3AWypY="; x-main=4r7ZrJJV4BT1R2sWn2W4NpiXZm9RSJLD; at-main=Atza|IwEEEEE4EikDns-CTHnGRqXXXcnnaij75AfcF1-XOBvphYTp_ATJHu6f0vDgMI7B1ApWn51cP6bqvG-XXXXeTPD8t7jl5El_FdhlYn3mmtn476FfnI5E7anoZNSKLyE-jauNJssBeGUjsSd0z8746mujYcJbKQsMMVVUlxcu4jXXxXXYcC4GasQyvOIp92wY-TPKAOys8NV0-yXH4xTGBzgJ0zzJa5JvyRz2v0x3fijvyXXXXXXSDhZtaDOZ6GOQlYrsUmudsorYUcUT52x0EYavXXXXX92cmgkMUzuTxppV1SpLk2Wk63LQQkCCZLs6_HWlnX2Saf0zgc13BdUehhSBiYHzJJeg1Ys7g68GLG5IuSGvyGe8ebmcN9KUDdD2CwphaeW34iy6dVKGbUpJ3GKVlz; sess-at-main="eSHstcxm5Krki5T1EAcQyk9XXXXXXqMbqcJqDBaA="; csrf=-2012345694' -H 'Connection: keep-alive' -H 'Content-Length: 0' --compressed
You have to define the Variables in the shell-scripts - and you can control volume, select TuneIn or Pandora stations from the command line.
