🚀 Reply API V3 — Changelog (August 27, 2026)

Three small additions and one correction. If you create schedules through the API, read the last part.

🟢 Now Live Inbox — reply to a different address.

POST /v3/inbox/threads/{id}/messages

takes an optional

to

(

string

,

format: email

, nullable), for when a colleague or a shared inbox answered instead of the contact. Omit it and nothing changes. Note: setting it switches off link and open tracking for that message. Settings — tracking and plain text.

GET

/

PATCH /v3/settings

now expose

isLinksTrackingEnabled

and

isSendingPlainTextEnabled

(both

boolean

, nullable) in the

emails

section. They don't mix — plain text can't be enabled while open or link tracking is on:

400  settings.invalidOperation
     Cannot enable plain text mode together with open or click tracking

LinkedIn — delay between actions.

PUT /v3/linkedin-accounts/{id}/limits

takes

actionDelayMinSeconds

(

>= 30

, default

60

) and

actionDelayMaxSeconds

(<= 86400`, default

120

, with

max - min>

= 60`). Reply picks a random delay in

[min, max]

before each action. ⚠️ That

PUT

replaces the whole limits object — omit the two fields and you get the 60–120s defaults, which changes pacing even if your code doesn't change. ⚠️ Schedules —

timezoneId

never took IANA identifiers Our docs said IANA (

"America/New_York"

). The API takes Windows identifiers and rejects IANA. Nothing changed in the API — the documentation was wrong, and anyone who trusted it has been getting rejections. Map before calling

POST /v3/schedules

or `PUT /v3/schedules/{id}`:

"America/New_York"

→

"Eastern Standard Time"

,

"Europe/London"

→

"GMT Standard Time"

. 📝 Also: 276 endpoint descriptions across 30 areas were rewritten. No contract changes, but they now spell out behavior that was always true — notably on

PATCH /v3/settings

, where an explicit

null

clears a text field but is ignored on booleans and numbers, and

calls.resolutions

replaces the whole list, so a custom resolution you omit is deleted. 📚 Full documentation
