# Changelog

Notable changes to the Hook API.

## 2026-10-01 v1.0.37

- Signals now report who closed them (`closedById`) and whether they were
dismissed automatically (`autoDismissed`).


## 2026-09-11 v1.0.36

- Signals now report their data source.


## 2026-09-08 v1.0.35

- Fixed a bug where the `updatedSince` filter on the customer list and the
`minStartDate` filter on the meeting list accepted timestamps without seconds,
such as `2026-09-08T12:00Z`. Both now require them.


## 2026-08-20 v1.0.34

- **Experimental:** the customer list can now be filtered by custom field
value, e.g. `?customFields.tier=gold`. This filter is experimental — its
syntax, supported data types and errors can change at any time without
warning, and integrations using it may break unexpectedly as a result. See
the [Custom field filtering](/guides/custom-field-filtering) guide.


## 2026-08-18 v1.0.33

- The customer list can now be filtered by segment, domain, country, region and
city, by a customer's ID in an external source such as your CRM, and by when a
customer was last updated.
- Customers now report when they were last updated, and signals now report the
member who last updated them.


## 2026-08-17 v1.0.29

- Meetings are now in the API. List the meetings for a customer, or fetch a
single meeting along with its transcript.
- You can now create a note on a customer, and list the note categories your
organization has available.


## 2026-08-12 v1.0.26

- Briefs are now in the API. List the briefs for your organization and read the
contents of a brief for a given customer.


## 2026-07-30 v1.0.25

- The customer list can now be filtered to the customers a particular member is
assigned to, optionally narrowed to a single role such as CSM.


## 2026-07-08 v1.0.24

- You can now read the notes recorded against a customer.


## 2026-07-07 v1.0.22

- Tidied up how nullable fields are described in the spec.


## 2026-06-23 v1.0.21

- Automations are now in the API. List your automations, fetch one by ID, and
read the logs for its triggers and actions.


## 2026-06-05 v1.0.19

- The deprecated `notes` field on a signal now always returns `null`.


## 2026-06-02 v1.0.18

## 2026-06-02 v1.0.17

- Documented the status values for customers and signals.


## 2026-05-06 v1.0.16

generated clients pick the right types.
