Overview

Updates the configuration of an existing stream. Use this endpoint to modify a stream's name, filter function, destination, destination attributes, extra destinations, batch size, metadata settings, reorg handling, distance-from-tip, notification email, and other configuration options without needing to delete and recreate the stream.

Key capabilities:

• Change webhook URL or destination credentials
• Update filter functions on-the-fly
• Switch compression settings
• Adjust retry parameters
• Add or modify extra destinations
• Update batch size and elastic batching settings

note

The network, dataset, and region fields cannot be changed after stream creation. To change these, create a new stream instead.

Endpoint

Send a PATCH request to update an existing stream.

PATCH https://api.quicknode.com/streams/rest/v1/streams/{id}

Path Parameters

Parameter	Type	Required	Description
id	string	Yes	The unique identifier (UUID) of the stream to update

status	string	No	active or paused
elastic_batch_enabled	boolean	No	Deliver whatever blocks are available at the chain tip without waiting for the batch to fill
fix_block_reorgs	integer	No	1 to enable reorg detection
