I haven’t gotten a chance to look into hooks in the existing code yet, (and I’m not a dev just gpt enabled). But I was really just looking to send the name & email to a list, so not unusual. I’m just trying to solve for my contact page submission, which are often leads, getting added to a newsletter list. like via a webhook etc. To me this seems like an obvious thing, but it’s not common. I don’t want a bloated form, so was just looking to see how to make it happen with CFX. appreciate your work! - This reply was modified 8 months ago by [kp](https://wordpress.org/support/users/kp/).

I really appreciate your help from WPMU DEV in working through this and having the patience. It would have been easy to just point the finger at another plugin.

As you can see from the error message above, it’s specifically that the API REST as been “previously declared”. so you would need api data – in my case the same 2 data elements- in both Hustle and ‘Contact Form 7 Campaign Monitor Extension’ which is an addon for Contact 7, to really recreate the issue. I don’t think just installing them will recreate the conditions. * cheers, kurt * Forum: [Plugins](https://wordpress.org/support/forum/plugins-and-hacks/) In reply to: [[Hustle - Email Marketing, Lead Generation, Optins, Popups] CONFLICT API REST_SERIALISATION](https://wordpress.org/support/topic/conflict-api-rest_serialisation/) * Thread Starter [kp](https://wordpress.org/support/users/kp/) * (@kp) * [9 years ago](https://wordpress.org/support/topic/conflict-api-rest_serialisation/#post-9288147) * Hello Jdailey, thanks for that info and idea.
