X retires the Account Activity replay endpoint for POST /2/webhooks/replay
What changed
On March 20, 2026 X deprecated POST /2/account_activity/replay/webhooks/{webhook_id}/subscriptions/all, effective March 25, 2026 at 12:00 PM ET, and pointed developers to the consolidated POST /2/webhooks/replay endpoint, which it says provides identical functionality.
What it means
Tools that replay missed Account Activity webhook events must call the consolidated POST /2/webhooks/replay endpoint instead of the old account_activity replay route.
Who is affected
Developers of webhook-based X integrations that recover missed events with replay jobs.
What to do by 25 Mar 2026
Replace POST /2/account_activity/replay/webhooks/{webhook_id}/subscriptions/all with POST /2/webhooks/replay, which X says provides identical functionality.
What this means for you
If an app misses some alerts from X, for example while its server was down, it can ask X to send them again. X moved that "send again" feature to a new address in March 2026. Apps that still use the old one can't recover missed alerts. This mostly matters to app makers, not to people posting.
The details
- Deprecated:
POST /2/account_activity/replay/webhooks/{webhook_id}/subscriptions/all, effective March 25, 2026 at 12:00 PM ET. - Replacement:
POST /2/webhooks/replay("Create a replay job for webhook"). X says it "provides identical functionality". Like the other/2/webhooksendpoints, it uses an OAuth 2.0 App Only Bearer Token. - Doc mismatch: the Account Activity API introduction still lists the old replay route in its reference index.
- Context: the same introduction says the Account Activity API itself "is being deprecated", with no date, in favour of the X Activity API.
What to do next
- Business owners: Nothing.
- Marketers and agencies: Nothing.
- Developers: Point replay jobs at
POST /2/webhooks/replayand remove calls to the old route.
