Copy custom field to Track Package Power-up with Butler

[Robin Moore]

I'm already capturing the tracking number in a custom field, is it possible to copy it to the Track Packager Power-Up's tracking field with Butler? I'm guessing not directly but with an API call?

In general to change a power up managed content that capability must be made via by the developer.

Right, but the power up must be storing the tracking number in the card using the Trello API, I could copy my tracking number to the same location using the same API call

There is a 4K plug-in data per card which you can read if the developer so decide to use that. Some power up keep them as attachment eg Typeform. So keeps the data in their own system and bring them into the card like Contalist.   I have yet to find a way to write into these placeholders. In the case of Contalist it has some api for you to read and write the data. You should try to contact the developer.
