Summary: Create and manage scheduled Function Triggers from the Neon Console, the neon triggers CLI, the Neon API, or neon.ts: a Hono handler for the scheduled POST, a five-field UTC cron reference, how to confirm a run in the logs, and the common errors.

Create and manage scheduled Function Triggers.

Schedule a function to run recurring work as your own code: a nightly report, a cleanup job, a periodic sync, or a health check. It runs next to your data and fires even when the compute is scaled to zero.

This guide creates a scheduled trigger, then covers listing, updating, disabling, and deleting it. For what a trigger is and how it behaves across branches, see the overview. You can manage scheduled triggers from the Neon Console, the neon triggers CLI, the Neon API, or declaratively in neon.ts; the steps below show each.

You need a deployed function and its slug. The CLI and API also need a Neon API key; the Console doesn't. If you deployed with the CLI, neon link already wrote your project and branch to a .neon file; you can also find the IDs in the Neon Console.

The API examples use these variables:

export API="https://console.neon.tech/api/v2"
export NEON_API_KEY="<your-api-key>"
export PROJECT_ID="<your-project-id>"
export BRANCH_ID="<your-branch-id>"

To build this with an AI agent, start from this prompt and fill in the task:

Create a Neon Function that <task>, then schedule it with a Function Trigger.
Docs: https://neon.com/docs/compute/functions/triggers/schedule.md

- Add one unauthenticated POST route (scheduled invocations arrive without credentials). Read `data.scheduled_at` from the JSON body; keep the handler idempotent.
- If the task uses Postgres, connect with the injected DATABASE_URL.
- Deploy it, then create a schedule trigger via the Neon API with a five-field UTC cron. Start at `* * * * *` to confirm a run, then PATCH to the real cadence.
- The route and trigger both default to `/`; set `function_path` on both if you want a different path.

A scheduled invocation is a POST whose JSON body carries the occurrence: data.scheduled_at, the trigger that fired, and an invocation_id. Neon delivers it to the function's public URL, so the route sits outside your auth middleware. You can confirm the call came from Neon with the X-Neon-Trigger-Invocation-Id header (see Confirming a request came from Neon); keep the handler idempotent and guard destructive actions regardless.

This Hono function checks a URL and records the result:

import { Hono } from 'hono';
import { neon } from '@neondatabase/serverless';

const app = new Hono();
const sql = neon(process.env.DATABASE_URL!);

// This route is public. Neon strips client-set X-Neon-* headers, so the presence of
// X-Neon-Trigger-Invocation-Id attests the call came from Neon's trigger system.
app.post('/', async (c) => {
  if (!c.req.header('x-neon-trigger-invocation-id')) {
    return c.json({ error: 'not a trigger call' }, 403);
  }

  const { data } = await c.req.json<{ data: { scheduled_at: string } }>();
  const scheduledAt = data.scheduled_at;

  const started = performance.now();
  const res = await fetch('https://example.com', { signal: AbortSignal.timeout(10_000) });
  const latencyMs = Math.round(performance.now() - started);

  await sql`
    INSERT INTO checks (scheduled_at, status_code, latency_ms)
    VALUES (${scheduledAt}, ${res.status}, ${latencyMs})
    ON CONFLICT (scheduled_at) DO NOTHING
  `;

  console.log(`check ${scheduledAt}: ${res.status} in ${latencyMs}ms`);
  return c.json({ ok: true, scheduled_at: scheduledAt, status: res.status });
});

export default app;

DATABASE_URL is injected for you. See Environment variables. The ON CONFLICT (scheduled_at) DO NOTHING clause makes a redelivered occurrence a no-op.

Create the table it writes to, in the Neon SQL Editor or with neon psql:

CREATE TABLE IF NOT EXISTS checks (
  scheduled_at timestamptz PRIMARY KEY,
  status_code  int,
  latency_ms   int
);

Then deploy the function:

neon functions deploy uptime --src functions/uptime.ts

With the function deployed, create a schedule trigger. Start with * * * * * so you can confirm the trigger in under a minute, then move it to a real cadence below.

Console

In the Neon Console, open Functions, click the ⋮ menu next to your function, and select Manage Triggers. Click Create trigger (the Function is already set to the one you opened) and choose Schedule under Trigger type, then fill in:

• Trigger name: a label, unique across the branch, including inherited triggers.
• Function path: the request path sent to the function. Defaults to /.
• Cron schedule: five numeric fields: minute, hour, day of month, month, day of week. See Cron reference.
• Timezone: fixed to UTC; schedules are always evaluated in UTC.
• Enable trigger: on by default.

Click Create trigger to save.

CLI

neon triggers create needs --function-slug, --name, and --cron; --function-path and --enabled are optional.

neon triggers create --function-slug uptime --name uptime-check --cron '* * * * *'

The CLI resolves the project and branch from your context file, or pass --project-id and --branch. See neon triggers for the full command reference.

API

POST to the branch's triggers collection. type, function_slug, name, and schedule are required; function_path and enabled are optional.

curl -X POST "$API/projects/$PROJECT_ID/branches/$BRANCH_ID/triggers" \
  -H "Authorization: Bearer $NEON_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "type": "schedule",
    "function_slug": "uptime",
    "name": "uptime-check",
    "schedule": { "cron": "* * * * *" },
    "function_path": "/",
    "enabled": true
  }'

Neon responds 201 with the trigger wrapped in a trigger object:

{
  "trigger": {
    "type": "schedule",
    "trigger_id": "trigger-1a2b3c4d-5e6f-7890-abcd-ef1234567890",
    "function_slug": "uptime",
    "name": "uptime-check",
    "function_path": "/",
    "schedule": { "cron": "* * * * *" },
    "enabled": true,
    "version": 1347042,
    "next_run_at": "2026-09-08T19:31:00.000000Z",
    "inherited": false
  }
}

next_run_at is when the first run happens. It's in UTC and advances automatically after each run.

neon.ts

Declare the trigger in the top-level triggers record in neon.ts, with function pointing at your function's slug, then apply it with neon deploy. cron is a five-field UTC expression.

functions: {
  uptime: {
    name: "Uptime",
    source: "./functions/uptime.ts",
  },
},
triggers: {
  "uptime-check": {
    type: "schedule",
    function: "uptime",
    cron: "* * * * *",
  },
},

The schedule is every minute, so wait about a minute, then read the function's logs:

neon logs query --source function

Your check ... line appears with the scheduled_at value read from data. See Observability for why that line matters.

To iterate on the handler without waiting for the clock, replay the payload against neon dev locally. See Test triggers locally.

Once you've seen a run, move the trigger to its real cadence (see Manage triggers). Left at * * * * *, it keeps invoking the function every minute.

A schedule is a five-field numeric cron expression, always interpreted in UTC.

To track local time, convert to UTC yourself, and account for daylight saving shifts. You can test your expressions with crontab.guru.

Ranges (1-5), lists (0,30), steps (*/2), and fixed values all work, down to every minute, with no maximum interval. Fields are numeric, so use numbers for days and months (1 for Monday, 1 for January), not names. A value outside its field's range (70 * * * *), a named day or month (0 9 * * MON, 0 0 1 JAN *), a macro (@daily, @hourly), a seconds field (* * * * * *), or a zero step (*/0 * * * *) each return a 400.

List, update, disable, and delete triggers from the Console, CLI, or API. Triggers declared in neon.ts are managed by editing the declaration and re-running neon deploy.

Console

Open Functions → ⋮ → Manage Triggers for the function. The panel lists that function's triggers with their schedule, next run, and enabled state. From there you can edit a trigger's fields, toggle Enable trigger on or off, or delete it.

CLI

The neon triggers command group manages triggers by ID:

neon triggers list
neon triggers get <trigger-id>
neon triggers update <trigger-id> --cron '0 3 * * *'
neon triggers disable <trigger-id>
neon triggers enable <trigger-id>
neon triggers delete <trigger-id>

See neon triggers for every subcommand and flag.

API

These examples use $TRIGGER_ID, the trigger_id from the create response.

List triggers on a branch

curl "$API/projects/$PROJECT_ID/branches/$BRANCH_ID/triggers" \
  -H "Authorization: Bearer $NEON_API_KEY"

{
  "triggers": [
    {
      "type": "schedule",
      "trigger_id": "trigger-1a2b3c4d-5e6f-7890-abcd-ef1234567890",
      "function_slug": "uptime",
      "name": "uptime-check",
      "function_path": "/",
      "schedule": { "cron": "0 3 * * *" },
      "enabled": true,
      "version": 1347043,
      "next_run_at": "2026-09-09T03:00:00.000000Z",
      "inherited": false
    }
  ]
}

The list is ordered by trigger_id, includes triggers inherited from a parent branch, and returns every trigger on the branch in one response.

Get one trigger

curl "$API/projects/$PROJECT_ID/branches/$BRANCH_ID/triggers/$TRIGGER_ID" \
  -H "Authorization: Bearer $NEON_API_KEY"

Returns the same { "trigger": { ... } } shape as create.

Update a trigger

PATCH is partial, but it must include the type discriminator plus at least one field to change. You can change function_slug, name, function_path, schedule, and enabled.

curl -X PATCH "$API/projects/$PROJECT_ID/branches/$BRANCH_ID/triggers/$TRIGGER_ID" \
  -H "Authorization: Bearer $NEON_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "type": "schedule", "schedule": { "cron": "0 3 * * *" } }'

A successful update returns 200 with the full object. version increases and next_run_at is recomputed against the new schedule.

Disable and re-enable

Disabling keeps the trigger but stops scheduling it:

curl -X PATCH "$API/projects/$PROJECT_ID/branches/$BRANCH_ID/triggers/$TRIGGER_ID" \
  -H "Authorization: Bearer $NEON_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "type": "schedule", "enabled": false }'

Disabling sets next_run_at to null and increments version. Send "enabled": true to start it again; next_run_at is recomputed from the current time.

Delete a trigger

curl -X DELETE "$API/projects/$PROJECT_ID/branches/$BRANCH_ID/triggers/$TRIGGER_ID" \
  -H "Authorization: Bearer $NEON_API_KEY" -i

HTTP/1.1 204 No Content

Note: Disabling or deleting stops future runs, but a run already queued for the upcoming minute still fires. To skip an imminent run, change the trigger well before that minute, not in the same instant.

In the platform logs, a scheduled invocation looks like any other HTTP call: the invoke begin and invoke end lines under the neon.function.request scope are the same either way. Trace a run from your own handler output instead. A console.log that includes scheduled_at gives you a searchable line tied to the run that produced it:

console.log(`check ${scheduledAt}: ${res.status} in ${latencyMs}ms`);

Your output appears under the neon.function.app scope, in the Console's Functions tab and in:

neon logs query --source function

Function logs come from neon logs query --source function, not the functions command group. Standard Node instrumentation such as Sentry or OpenTelemetry also works, and the incoming traceparent header ties a run into an existing trace.

The API and CLI reject a bad request with an HTTP status and message:

The request body is strict: any field not in the schema is rejected rather than ignored, so a typo fails loudly. In particular, the function is identified by function_slug; there's no function_id field.

pg_cron schedules SQL inside Postgres. A scheduled Function Trigger runs your function code instead. They solve different problems:

• Function Triggers overview
• Trigger on an object upload: the object-created trigger type
• Triggers in neon.ts: declare triggers as code
• pg_cron: schedule SQL inside Postgres instead
• Deploy and manage
• Authentication
• Logs

• Overview
• Trigger on object upload
