I have created a custom plugin within WordPress to POST contact form 7 data to an external API when a client submits their info, I followed a tutorial on YouTube step by step, but nothing is being posted to the API URL. I am not sure if it’s because the coding for contact form 7 is outdated now or if I am possibly using wp_remote_post incorrectly.
