I’m trying to make an extension that generates a file using base data and then re-uploads that file back to Airtable. However, I’m not able to find any way to access the upload attachment HTTP endpoint from within the Blocks SDK. The API reference only shows examples of “uploading” attachments using public URLs.
Is there any way to access this functionality (properly) from within a blocks extension? Or alternatively some sort of internal PAT or similar I can use to make the POST request without hardcoding something that will be exposed in the browser?
