ruby-on-rails - gmail newsletter/promotion tag?

Question

I am trying to get promotional and newsletter email messages using Gmail API. Currently, I am requesting the Gmail API based on sender, but it is not feasible. Is there a way to identify an email message as promotions or newsletters, when getting messages using Gmail API?

Is there a meta tag for newsletters or promotional messages?

Any help regarding this will be appreciated.

Thank you! J.

The tag you mentioned in the question is called label in Gmail API. You can find a list of default labels in the documentation: https://developers.google.com/gmail/api/guides/labels

I guess you are interested in CATEGORY_PROMOTIONS. In that case, you should pass it as a query param called labelIds[] of the request, that lists user's messages: https://developers.google.com/gmail/api/v1/reference/users/messages/list
