Large Webhooks

Forward webhooks larger than 4 MB

Webhook Relay buckets have a default webhook size limit of 4 MB. If a provider sends larger payloads, enable Large webhooks on the bucket to receive and forward webhook requests up to 40 MB.

This is useful for providers that include large JSON payloads, documents, images, or other files in webhook requests.

Enable large webhooks

1. Open the Buckets page.
2. Open the bucket you want to configure.
3. Select the Settings tab.
4. Turn on Large webhooks.
5. Click Save.

Once enabled, the bucket can accept and forward webhook requests up to 40 MB.

Need to forward webhooks larger than 40 MB?

Webhook size limits can be raised to 100 MB or beyond. Contact support with your expected payload size and use case so we can configure the right limit for your account.
