    The signature received in the callback does not coincide with the one recreated!
    The params that I receive are: customizedData, eventId, timestamp, userId, signature (like this):
    .../test.php?customizedData=%7B%22game%22%3A%22sudoblock%22%7D&eventId=60230082-a1f2-42ce-9159-703b38dfb734&timestamp=1651775611&userId=123456&signature=744baef2fd00c440108897fh309d7a90


    I generate the string to hash in this way as described in the documentation:
    "eventId,timestamp,userId"     --->       "60230082-a1f2-42ce-9159-703b38dfb734,1651775611,123456"


    The secret key generated in the Unity Dashboard for hashing is in this format:
    84e7d31e-7n14-452b-abd9-781du4229e10


    And that's the PHP code to generate the signature:
    hash_hmac ('md5', $stringToHash, $secretKey);


    I tried any different combination but is not working, the received signature is different from the recreated one...

    could you provide the game id and when did you experience this issue so i can look into the logs to find out more information?

    also have you tried regenerating the secret to see if that helps solve the issue?
