First of all install
Contact Form 7 (CF7) plugin and yes it is the most usable plugin by 1+ million wordpress websites.
You can send data to any endpoint webhook url!
Discalimer: This plugin has been made without any encouragement of cf7 developers or webhook/API service.
How to perform
Just activate the CF7 plugin and webhook configuration plugin then you are ready to webhook any URL to send data.
In the configuration part there are another options like special tags and headers to send over the given URL. The options describes that the hidden tags and special tags can be send over the URL also as per your requirement.
There is one more option available in the configuration area(Data Skip to Webhook) for the skipping tags, where the cf7 form tags can be skipped for the integration process, which means if the developer doesn't wish to send entire data of cf7 form and want to send some specific data then the skipping tag will help on that.
Installation
Install first Contact Form 7 plugin (
