How to add or update webhooks for existing Items

To add or update a webhook for a pre-existing Item, submit a POST request to /item/webhook/update with the new or updated webhook:

curl -X POST https://sandbox.plaid.com/item/webhook/update \
 -H 'content-type: application/json' \
 -d '{
   "client_id": String,
   "secret": String,
   "access_token": String,
   "webhook": "https://plaid.com/updated/hook"
 }'

Plaid sends a WEBHOOK_UPDATE_ACKNOWLEDGED webhook when you successfully update an Item’s webhook.

Example WEBHOOK_UPDATE_ACKNOWLEDGED webhook:

{
   "webhook_type": "ITEM",
   "webhook_code": "WEBHOOK_UPDATE_ACKNOWLEDGED",
   "item_id": "wz666MBjYWTp2PDzzggYhM6oWWmBb",
   "error": null,
   "new_webhook": https://plaid.com/example/webhook"
  }
