I want to know is there a way to create jira issues in a website. For example there is a a contact form already existed in the site, when i filled the contact form, a jira issue is automatically created in JIRA
You can make your form send email to predefined JIRA email adress and make JIRA can cerate issue from that. This should require only making the right settings in JIRA.
Second way may be via JIRA REST API. You can authorize your website against JIRA and then simply let it create the issue from data you will send to it. This will require more coding and making your website comunicate via REST API with JIRA.
Yes, i know it is for getting feedback but it does not stop you to use it as a contact form.
However, for example, if you want the old contact form you can try the below, otherwise as suggested by @MoroSystems Support
