Edit chainhooks

Modify existing chainhooks including filters, actions, and options

The Platform UI does not currently support editing chainhooks. You must use the SDK or API to make updates.

Basic Update Example

1
import { ChainhooksClient, CHAINHOOKS_BASE_URL } from '@hirosystems/chainhooks-client';

2


3
const client = new ChainhooksClient({

4
  baseUrl: CHAINHOOKS_BASE_URL.testnet,

5
  apiKey: process.env.HIRO_API_KEY!,

6
});

7


8
await client.updateChainhook('chainhook-uuid', {

9
  name: 'Updated chainhook name',

10
  filters: {

11
    events: [{ type: 'ft_transfer', asset_identifier: 'SP...ABC.token::usdc' }],

12
  },

13
});

Add event filter (while preserving existing events)

In order to add a new event filter to an existing chainhook, you can fetch the current definition, modify it, and then update it.

1
// ✅ Good: Fetch first

2
const current = await client.getChainhook(uuid);

3
await client.updateChainhook('chainhook-uuid', {

4
  filters: {

5
    events: [

6
      ...(current.definition.filters.events ?? []),

7
      { type: 'contract_call', contract_identifier: 'SP...XYZ.counter' },

8
    ],

9
  },

10
});

11


12
// ❌ Bad: Will overwrite any existing events

13
await client.updateChainhook(uuid, {

14
  filters: { events: { type: 'contract_call', contract_identifier: 'SP...XYZ.counter' } },

15
});

Update Multiple Fields

1
await client.updateChainhook('chainhook-uuid', {

2
  name: 'Updated name',

3
  filters: { events: [{ type: 'stx_transfer', sender: 'SP...SENDER' }] },

4
  action: { type: 'http_post', url: 'https://new-url.com/webhooks' },

5
  options: { decode_clarity_values: true },

6
});

7


8
const updated = await client.getChainhook('chainhook-uuid');

9
console.log('Updated:', updated.definition.name);
