This response does not have an example.
Add or remove individual addresses from a webhook subscription without replacing the entire list. This is useful when you want to incrementally manage your subscribed addresses.
If you need to replace the entire address list at once, use the Replace Webhook Addresses endpoint instead.

​
Example Use Cases

​
Add New Addresses

Add one or more addresses to your existing subscription: 
{
  "add_addresses": [
    "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
    "0x1234567890123456789012345678901234567890"
  ]
}

​
Remove Addresses

Remove addresses that you no longer want to monitor: 
{
  "remove_addresses": [
    "0x3f60008Dfd0EfC03F476D9B489D6C5B13B3eBF2C"
  ]
}

​
Add and Remove in One Request

You can add and remove addresses in the same request. The removal happens first, followed by the additions.
{
  "add_addresses": [
    "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb"
  ],
  "remove_addresses": [
    "0x3f60008Dfd0EfC03F476D9B489D6C5B13B3eBF2C"
  ]
}
This endpoint only manages addresses. To update other webhook properties like name, URL, or status, use the Update Webhook endpoint.
