Attachments fields

Attachment fields in Airtable expose only temporary links that expire after a certain period. To ensure persistent access to attachments, we transform them into API proxy links when syncing attachment fields.

Transformed Link Format

Attachment URLs are converted to this format:

https://eu.api-proxy-dev.stacksync.com/v1/airtable_attachment?dt=eyJiYXNlX2lXUGdEIiwgInBhdGgiOiAiIn0=

How to Use Attachment Links

1. Set up an API Proxy - You'll receive an API key upon creation

2. Make the request - Include your API key in the Authorization header:

   curl -X GET "https://eu.api-proxy-dev.stacksync.com/v1/airtable_attachment?dt=eyJiYXNlX2lXUGdEIiwgInBhdGgiOiAiIn0=" \
   -H "Authorization: Bearer <your_api_key>"

1. Automatic redirect - The API proxy will:

   • Fetch the current attachment URL from Airtable

   • Redirect you to the updated link automatically

This ensures your attachment links remain valid without manual updates.
