Sanity Webhooks for Cache Invalidation

Set up automatic cache invalidation when content is updated in Sanity.

Setup​

  1. Go to Sanity Manage
  2. Select your project
  3. Go to API → Webhooks
  4. Click Create webhook

Configuration​

Configure the webhook with:

  • Name: Cache Invalidation
  • URL: https://your-domain.com/api/webhooks/sanity
  • Dataset: production (or your dataset)
  • Trigger on: Create, Update, Delete
  • HTTP method: POST
  • Secret: Set SANITY_WEBHOOK_SECRET in your env
  • HTTP Headers: 
    Authorization: Bearer ${SANITY_WEBHOOK_SECRET}

Testing​

Test the webhook manually:

curl -X POST https://your-domain.com/api/webhooks/sanity \
  -H "Authorization: Bearer your-secret" \
  -H "Content-Type: application/json" \
  -d '{"_type": "hero"}'

How It Works​

  1. Content is published in Sanity
  2. Sanity sends webhook to your API
  3. API validates the webhook secret
  4. Cache is automatically cleared
  5. Next request fetches fresh content
