Hi @evehryday,
I have found a similar post here that might help you. 😊
Basically, to retrieve custom Attributes through the API integration, you have to whitelist these attributes under the API credentials settings.
This is visible in Settings > Integrations > API Credentials > Corresponding API Credentials > Readable Attributes. You can add the mentioned attributes to the list. This will enable their retrieval through the API .
If you would like more information about the configuration, you can consult our Helpcenter article:
Generate and manage API credentials
I hope this helps! Please let me know if you have further questions. 😊
I wish you a lovely afternoon. 🙌
Regards,
Weena
Thank you very much. This is what I missed.
