Hi Olivia,
Not sure if anyone replied to you previously, if not, apologies!
Unfortunately using our API doesn’t change the way Veeqo itself behaves, our API is used to build external applications that use Veeqo data to complete functions not offered within the platform, for example, we have an integration with Amazon Alexa which uses our API to provide answers to voice commands like “Hey Alexa, tell me how many units I sold today…” but this is accessed through an Alexa extension and doesn’t work from inside Veeqo.
So because you are using custom fields in Shopify and we don’t currently pull in data from those fields in Veeqo you would need to create a external application that would draw that data from Shopify and pass it through to an appropriate field that already exists within Veeqo. I believe then it might defeat the purpose of the exercise because you’ll potentially wind up with one “Notes” field where you wanted 2 very specific fields.
I will check with the team and see if they are planning any updates within Veeqo in regards to custom carts in the future and let you know.
And happy to discuss the above in more detail if needs be.
