Hi @mkovcy,
Thank you for posting your questions.
Below you will find the answers to your questions.
Is it possible to get tracking number from rest api? Yes, this is possible. You can set up an API integration in your Sendcloud account in order to retrieve the parcel IDs associated with the labels created with your WooCommerce integration ang get the tracking number from the payload,??
You can find more information in our official API documentation here:

Also is it possible to save tracking number as order meta?
Currently, we send tracking information as a string in order notes. There is a feature request for sending the tracking number as order meta.. You can create a support ticket in order to have your Sendcloud User ID linked to the feature request and our support team will get back to you once the feature request has been implemented.
