## Context
Follow-up to the incident where 500s and latency spiked around 6pm until
the Recall webhook was disabled. Server routes
(`/webhooks/server/:resolverUid`) ran the resolver **and** the target
logic function synchronously inside the API request, so any handler
throw became a 500 and any slowdown past Svix's delivery timeout marked
the delivery failed — Svix redelivered, feeding load back into the API
in a self-sustaining storm.
## What changed
- Every server-route request acks with **202 `{ queued: true }`** as
soon as the resolver returns; the target runs on `logicFunctionQueue`.
Signature verification stays synchronous in the resolver and still
rejects with a non-2xx. External senders never observe target latency or
failures.
- The resolver contract is unchanged from main: `{ workspaceId,
targetLogicFunctionUniversalIdentifier, payload? }`.
- The target lookup still happens synchronously before enqueueing,
scoped to the resolver's application registration, so unknown targets
404 as before.
- Endpoints whose caller must read the response body (challenge
handshakes, Slack commands) should use `httpRouteTriggerSettings`
routes.
Final diff is 4 files: the server-route service, its spec, the
integration spec, and the docs page. Trigger jobs, fan-out, message
queue, shared types, and SDK are all untouched.
## Tests
- `server-route-trigger.service.spec.ts`: 202 ack + enqueue,
unknown-target 404 without enqueue, resolver auth/contract/error
mapping.
- Integration: `server-route-trigger-authorization.integration-spec.ts`
asserts the 202 queued ack (run locally against a seeded DB, green).
- `typecheck` + `lint:diff-with-main` + `oxfmt` clean.
## Notes
- **Breaking for existing server-route resolvers**: responses are always
202; the target's return value no longer reaches the caller. Existing
resolvers returning response bodies must move those endpoints to
`httpRouteTriggerSettings`.
- A queued target's handler failure is recorded in execution logs but
not retried (same as other queue-executed functions today); retry
semantics are deliberately out of scope here.
- Follow-up candidates: retry-on-failure semantics for queued
executions, `addBulk` for single-round-trip fan-out, declarative
signature verification to take resolver code out of the request path,
moving the call-recorder 250s artifacts import off the API request path.
- Companion PR #23135 (call-recorder): no app change needed for dispatch
— queued dispatch applies by default.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
