Payment form is not created. What is the reason?
You can retry by adding the "CURLOPT_SSL_VERIFYPEER=>false," line to the post function in the "srcIyzipayDefaultHttpClient.php" file.
Additionally, we will need you to verify that
1) Your TLS version is 1.2 (it is not sufficient that TLS 1.2 is active, your server needs to communicate with iyzico through using TLS 1.2)
2) Your OPEN SSL version is 1.0.2
3) PHP version is 5.6 or above
I receive invalid signature error. What is the reason?
When data is sent to iyzico API, it is sent as encrypted through the creation of a hash to ensure the security of the secretKey. If such hash cannot be decrypted by iyzico, this issue is reflected as an error message.
Occasions which cause such an error are:
1. Entering the API and Security Key (API Key-Secret Key) wrong or leaving a space either at the beginning or end of such key value
2. Not using UTF-8.
I receive an invalid request error. What is the reason?
"Invalid request" error appears when parameters are not set in the appropriate format. One way is to control the format of the parameters you set. As a first step, you can check whether you separate the tens digits of the parameters with a full stop rather than with a comma. For instance, 1.0 instead of 1,0
