Uploading Attachments

⁠ Tip Jar ⁠ Thank Kuovonne for creating this content! ⁠ ⁠ ⁠

⁠

Uploading local files in bulk

You can upload files on your local computer to an attachment field in bulk using a

Gallery View⁠

Uploading attachments via automations or code

If you want to upload an attachment using an automation, scripting, or third party integration, the attachment must be hosted at a publicly accessible url.

Airtable cannot upload files from viewer URLs that show the file in a viewer (versus the raw file) or URLs that require a user to be logged.

Accessing attachments shortly after upload

When you upload an attachment, the url starts out as a temporary url, for a fraction of a second (or sometimes a little longer), so it is best to wait a few seconds after uploading the attachment before attempting to access the file.

In scripting, I tend to wait a few seconds and then check for a thumbnail url. If the there is a thumbnail url, the attachment is good to go. If there is no thumbnail (for a file type that can get a thumbnail), I wait a few more seconds. If there still isn’t a thumbnail, I either fail and warn the user or I try again with a cache-busting variation on the source url, depending on the use case.
