CRM/ERP integration with the #1 ERP solution Odoo (Open Source) with CRM included. Sync ecommerce data from Woocommerce, contact data and tags etc.

An integration of CleverReach would be awesome. Developer-API: https://rest.cleverreach.com/explorer/v3/

Mailster is a popular email autoresponder/crm for WordPress. Being able to send subscribed Contacts to it via wpfusion would be great.

Integration with Wishpond CRM (https://www.wishpond.com/)

Integration with Automizy CRM (https://automizy.com/) Would be a limited, one-way sync, since they don’t have webhooks.
