Does anyone know how to do this. I called support and I was told to try asking here. I hope there is a way because unfortunately if I cant find one I do have to switch 
I use Liondesk, that is CRM I am trying o connect with and it is API.
Hi,
It seems that LionDesk has a REST API https://developers.liondesk.com/docs/getting-started
You can use it to send/receive information from/to your wix site.

What if you need to push data to a 3rd party rather than fetch or pull?
I’m assuming that by push data you mean you want to POST data somewhere. In this case you can still use Fetch to post.
You can also expose your site API using http functions and use external apps, sites to consume your endpoint https://www.wix.com/corvid/reference/wix-http-functions.html
