Hi, Using kiteconnect Version 3.0.2b php class file; Access token is not generated. When I checked it throws error of Authentication failed: Invalid `checksum` while calling generateSession function. $requestToken and $api_secret key is correctly passed.
public function generateSession($request_token, $api_secret) { $checksum = hash("sha256", $this->api_key.$request_token.$api_secret);
Can you try again now? Should be fine.
