Can I setup a trigger through Teamleaders API when there are changes in Deals Custom Fields?

I would like to have a teamleader trigger in MAKE.com that triggers when there is a change to a custom field in a deal. Someone at teamleader told me i could use deal.changes for this, but i can’t find any documentation about this.

Usecase:
I want to enter booking details in my deal after the quote is accepted (and with that, the deal-status changed). I can trigger on deal-phase-changes, but i need a trigger once again after entering the booking details in custom fields. The trigger will start a sync with activecampaing, starting up a e-mail automation.

Question
Can anybody provide me with the details to be added to MAKE.com to receive this info through API?
