"An attachment url is disallowed" Send email action in Airtable Automations
What does the "An attachment URL is disallowed" error mean?
This error occurs when attempting to send an email via Airtable Automations, and the URL for an attachment is not accepted. This can be due to several reasons, including URL format, security settings, or recent updates to Airtable's platform.
What are common causes of this error?
Invalid URL Format: The URL for the attachment may not be correctly formatted or recognized by Airtable.
Security Restrictions: Airtable may block URLs from certain sources for security reasons.
Recent Updates: Platform updates can change how URLs are processed and validated, leading to previously working URLs being rejected.
Timing Issues in Automation: The "Send email" action may run before the previous action regarding the attachments is completed, causing the URL to be unavailable or incorrect at the time of email sending.
How can I fix the "An attachment URL is disallowed" error?
Here are several steps and solutions suggested by Airtable community members:
Check URL Validity:
Ensure the URL is correctly formatted and accessible. Try opening the URL in a browser to verify it works.

Avoid Certain URL Shorteners:
URLs from some URL shorteners or non-trusted sources might be blocked. Try using a direct link instead of a shortened URL.

One user mentioned that after a recent update, reconfiguring the automation to handle attachments differently resolved the issue .
Ensure Proper Timing in Automations:
