Webhook or getUpdates: Is This a Bot Migration or a Different Repair?
Compare Telegram update receivers by queue custody, confirmation state, endpoint ownership and cutover evidence before estimating a migration.
Signals to watch
- The current receiver and target receiver are explicitly named
- Pending updates and the getUpdates offset checkpoint have an agreed disposition
- Cutover, rollback, secret verification and acceptance events have owners
A Telegram bot migration between a webhook and getUpdates is a change of update receiver and delivery state, not a generic “move the bot” task. Before estimating it, identify the active receiver, the pending queue, the polling offset or webhook status, selected update types, authentication check, cutover moment and rollback owner. Bot API means Telegram’s application programming interface for bots; CRM means customer relationship management system.
This comparison is for a solutions consultant at a Telegram bot hosting and integration provider who reviews authorised developer, SaaS and ecommerce groups. The commercial Signal is a team that can name both the current and target delivery methods and owns a cutover window. “Webhook is slow, switch us to polling” is only a hypothesis. Calling every timeout a migration will make the quote target the wrong boundary.
The quick answer depends on who owns the receiver
Choose getUpdates when the application should actively request Updates through long polling and can own its offset checkpoint, worker lifecycle and single-poller discipline. Choose a webhook when Telegram should POST Updates to an owned public HTTPS endpoint and the team can operate endpoint availability, request verification and retry-safe processing.
Neither method is universally faster, cheaper or more reliable. Telegram’s Getting updates documentation calls them mutually exclusive. The correct question is which operating model fits the application’s infrastructure—and whether the observed problem is actually at the receiver.
| Scope question | getUpdates | Webhook |
|---|---|---|
| Who initiates delivery? | The bot application makes long-poll requests | Telegram sends HTTPS POST requests |
| What confirms progress? | A later offset greater than an update_id | Successful endpoint response plus application-side durable handling |
| What proves the active mode? | getWebhookInfo.url is empty and the poller is observed | getWebhookInfo.url names the configured endpoint |
| What state needs cutover care? | Offset checkpoint and one active poller | Endpoint, certificate/IP choices, secret token and response behaviour |
| Common false diagnosis | Poll loop stopped, offset mishandled or two pollers compete | Endpoint is healthy but handler or downstream action fails |
The table compares custody, not performance. Traffic volume, latency targets and infrastructure cost are unknown until the requester supplies them.
What the official methods establish
getUpdates uses long polling and returns an array of Update objects. Telegram says an update is confirmed when the next request uses an offset greater than that update’s update_id. A negative offset can retrieve from the end of the queue while forgetting earlier updates. That behaviour makes the checkpoint a migration asset: losing or guessing it can replay work or abandon updates.
The method has a timeout in seconds. Its default is zero, which is ordinary short polling, and Telegram says short polling should be used only for testing. That sentence does not say long-polling getUpdates is categorically a development-only method.
setWebhook registers an HTTPS URL. Telegram POSTs a JSON-serialized Update to it. If the response status is not 2XY, Telegram says it repeats the request and gives up after a reasonable number of attempts; the documentation does not provide a fixed retry schedule. The optional secret_token arrives in the X-Telegram-Bot-Api-Secret-Token header and can help the endpoint verify that the request belongs to the configured webhook.
deleteWebhook removes that integration when switching back to getUpdates. getWebhookInfo reports the current URL, pending-update count, IP, last-error fields, maximum connections and allowed update types. If the bot is using getUpdates, Telegram says the returned URL field is empty.
The pending queue is a business decision
Telegram states that incoming updates are kept no longer than 24 hours. Both setWebhook and deleteWebhook offer drop_pending_updates. Passing true discards all pending updates.
That parameter should never be buried in an implementation default. For an order bot, discarding queued messages may hide customer actions. For a test bot, replaying stale events may be more harmful than dropping them. The service owner must decide which history still has business value, and the migration plan must state how duplicates or stale actions are prevented.
Before cutover, record:
getWebhookInfooutput with secrets and sensitive network details redacted;- pending-update count and selected
allowed_updates; - last confirmed polling offset if
getUpdatesis active; - the timestamp after which new Updates belong to the target receiver;
- whether pending Updates will be drained, preserved for controlled replay or explicitly dropped;
- the application key used to prevent the same Update from producing a second business action.
Once those facts appear, arriving a day later may let another provider define the cutover first. Before they appear, speed does not repair the missing scope.
The duplicate-webhook repair covers idempotency, meaning repeated processing produces only one intended side effect. It is relevant to cutover testing but is not itself evidence that receiver mode must change.
Three messages that describe three different projects
“Webhook returns 200 but the CRM misses orders.” This is not yet a webhook-to-polling migration. Trace the Update through endpoint acceptance, durable handler state and CRM action using the four-receipt delivery map.
“Our private worker cannot expose an HTTPS endpoint; move the bot from webhook to long polling next maintenance window.” This describes a receiver-mode migration. It still needs queue disposition, offset ownership, single-poller enforcement and rollback.
“getUpdates stops after deployment and starts again when we restart the process.” This may be worker supervision, network timeout or checkpoint handling within the current mode. A public webhook can be an architectural option, but changing mode is not the only repair.
These examples contain no claim about a real customer or superior method. They show why the nouns in the group message determine the project owner.
A cutover plan with observable completion
A defensible migration has six checkpoints:
- Baseline: save active mode, allowed update types, pending count and last known application checkpoint.
- Pause: prevent two application instances from processing the same business actions during changeover.
- Queue decision: drain, preserve or explicitly drop pending Updates with owner approval.
- Switch: remove or set the webhook, then start exactly the intended target receiver.
- Acceptance: send owned test events for every required Update type and confirm one durable application result each.
- Rollback: state how the old receiver and its checkpoint can be restored without guessing.
Success is not “the process is running.” It is one active receiver, intentional queue custody, observed delivery of the required event types, duplicate-safe side effects and a rollback record.
What makes the group request worth immediate review
The strongest commercial thread names the bot environment, current and target methods, infrastructure owner, cutover deadline and a reason tied to operating constraints. It offers authorised evidence without pasting bot tokens or customer data. The weakest thread merely repeats “webhooks are bad” or “polling is slow.”
TOP Prospect can keep authorised fragments, source, time, repeated constraints and unknowns together so a solutions consultant reviews the migration-shaped request before generic bot complaints. It cannot inspect the bot, call Bot API methods, verify endpoint ownership, change infrastructure or contact the writer. New matching-target configurations in the current production interface are saved but do not automatically generate new candidates.
The bot timeout article helps separate hosting demand from application symptoms, and Bot API versus MTProto covers a different access-layer choice. Product options are on pricing.
Key facts
- Webhook and
getUpdatesare mutually exclusive receiver modes. getUpdatesconfirms progress through the offset; long polling is distinct from test-only short polling.- A webhook requires a public HTTPS endpoint and can carry a configured secret-token header.
getWebhookInfoexposes mode and queue evidence; an empty URL indicatesgetUpdatesuse.drop_pending_updatesintentionally discards queued Updates.- Method choice does not prove performance, root cause or commercial authority.
FAQ
Can both methods run for one bot?
No. Telegram documents them as mutually exclusive.
Is getUpdates only for development?
No. Telegram says short polling is for testing; getUpdates also supports long polling.
What does drop_pending_updates mean?
It discards pending Updates. The service owner should approve that outcome rather than inherit it from a script default.
What proves the migration is complete?
One active receiver, an intentional queue outcome, required event types delivered once to durable application state, and a tested rollback record.
Editorial review completed 26 August 2026 against Telegram’s getUpdates, setWebhook, deleteWebhook and getWebhookInfo documentation.
Frequently asked questions
Can a Telegram bot use a webhook and getUpdates at the same time?
No. Telegram documents them as mutually exclusive ways to receive updates for one bot.
Is getUpdates only for development?
No. Telegram says short polling should be used only for testing; getUpdates itself supports long polling. Suitability depends on the operating design.
What does drop_pending_updates do during migration?
It discards queued updates. Both webhook setup/removal paths expose this choice, so it must be an explicit business decision rather than a default.
What should a migration acceptance test prove?
It should prove one active receiver, an intentional queue disposition, delivery of selected update types, duplicate-safe processing and an owned rollback path.
