|

Subscribers can retrieve cached messaging using the [`poll=1` parameter](subscribe/api.md#poll-for-messages), as well as the

[`since=` parameter](subscribe/api.md#fetch-cached-messages).
|
||||

## Attachments
|
||||
If desired, you may allow users to upload and [attach files to notifications](publish.md#attachments). To enable
|
||||
this feature, you have to simply configure an attachment cache directory and a base URL (`attachment-cache-dir`, `base-url`).
|
||||
Once these options are set and the directory is writable by the server user, you can upload attachments via PUT.
|
||||
|
||||
By default, attachments are stored in the disk-cache **for only 3 hours**. The main reason for this is to avoid legal issues
|
||||
and such when hosting user controlled content. Typically, this is more than enough time for the user (or the auto download
|
||||
feature) to download the file. The following config options are relevant to attachments:
|
||||
|
||||
* `base-url` is the root URL for the ntfy server; this is needed for the generated attachment URLs
|
||||
* `attachment-cache-dir` is the cache directory for attached files
|
||||
* `attachment-total-size-limit` is the size limit of the on-disk attachment cache (default: 5G)
|
||||
* `attachment-file-size-limit` is the per-file attachment size limit (e.g. 300k, 2M, 100M, default: 15M)
|
||||
* `attachment-expiry-duration` is the duration after which uploaded attachments will be deleted (e.g. 3h, 20h, default: 3h)
|
||||
|
||||
Here's an example config using mostly the defaults (except for the cache directory, which is empty by default):
|
||||
|
||||
=== "/etc/ntfy/server.yml (minimal)"
|
||||
``` yaml
|
||||
base-url: "https://ntfy.sh"
|
||||
attachment-cache-dir: "/var/cache/ntfy/attachments"
|
||||
```
|
||||
|
||||
=== "/etc/ntfy/server.yml (all options)"
|
||||
``` yaml
|
||||
base-url: "https://ntfy.sh"
|
||||
attachment-cache-dir: "/var/cache/ntfy/attachments"
|
||||
attachment-total-size-limit: "5G"
|
||||
attachment-file-size-limit: "15M"
|
||||
attachment-expiry-duration: "3h"
|
||||
visitor-attachment-total-size-limit: "100M"
|
||||
visitor-attachment-daily-bandwidth-limit: "500M"
|
||||
```
|
||||
|
||||
Please also refer to the [rate limiting](#rate-limiting) settings below, specifically `visitor-attachment-total-size-limit`
|
||||
and `visitor-attachment-daily-bandwidth-limit`. Setting these conservatively is necessary to avoid abuse.
|
||||
|
||||
## E-mail notifications
|
||||
To allow forwarding messages via e-mail, you can configure an **SMTP server for outgoing messages**. Once configured,
|
||||
you can set the `X-Email` header to [send messages via e-mail](publish.md#e-mail-notifications) (e.g.

Otherwise, all visitors are rate limited as if they are one.
|
||||
|
||||
By default, ntfy runs without authentication, so it is vitally important that we protect the server from abuse or overload.
|
||||
There are various limits and rate limits in place that you can use to configure the server. Let's do the easy ones first:
|
||||
There are various limits and rate limits in place that you can use to configure the server:
|
||||
|
||||
* `global-topic-limit` defines the total number of topics before the server rejects new topics. It defaults to 5000.
|
||||
* **Global limit**: A global limit applies across all visitors (IPs, clients, users)
|
||||
* **Visitor limit**: A visitor limit only applies to a certain visitor. A **visitor** is identified by its IP address
|
||||
(or the `X-Forwarded-For` header if `behind-proxy` is set). All config options that start with the word `visitor` apply
|
||||
only on a per-visitor basis.
|
||||
|
||||
During normal usage, you shouldn't encounter these limits at all, and even if you burst a few requests or emails
|
||||
(e.g. when you reconnect after a connection drop), it shouldn't have any effect.
|
||||
|
||||
### General limits
|
||||
Let's do the easy limits first:
|
||||
|
||||
* `global-topic-limit` defines the total number of topics before the server rejects new topics. It defaults to 15,000.
|
||||
* `visitor-subscription-limit` is the number of subscriptions (open connections) per visitor. This value defaults to 30.
|
||||
|
||||
A **visitor** is identified by its IP address (or the `X-Forwarded-For` header if `behind-proxy` is set). All config
|
||||
options that start with the word `visitor` apply only on a per-visitor basis.
|
||||
|
||||
### Request limits
|
||||
In addition to the limits above, there is a requests/second limit per visitor for all sensitive GET/PUT/POST requests.
|
||||
This limit uses a [token bucket](https://en.wikipedia.org/wiki/Token_bucket) (using Go's [rate package](https://pkg.go.dev/golang.org/x/time/rate)):

|
|||
* `visitor-request-limit-burst` is the initial bucket of requests each visitor has. This defaults to 60.
|
||||
* `visitor-request-limit-replenish` is the rate at which the bucket is refilled (one request per x). Defaults to 10s.
|
||||
|
||||
### Attachment limits
|
||||
Aside from the global file size and total attachment cache limits (see [above](#attachments)), there are two relevant
|
||||
per-visitor limits:
|
||||
|
||||
* `visitor-attachment-total-size-limit` is the total storage limit used for attachments per visitor. It defaults to 100M.
|
||||
The per-visitor storage is automatically decreased as attachments expire. External attachments (attached via `X-Attach`,
|
||||
see [publishing docs](publish.md#attachments)) do not count here.
|
||||
* `visitor-attachment-daily-bandwidth-limit` is the total daily attachment download/upload bandwidth limit per visitor,
|
||||
including PUT and GET requests. This is to protect your precious bandwidth from abuse, since egress costs money in
|
||||
most cloud providers. This defaults to 500M.
|
||||
|
||||
### E-mail limits
|
||||
Similarly to the request limit, there is also an e-mail limit (only relevant if [e-mail notifications](#e-mail-notifications)
|
||||
are enabled):
|
||||
|
||||
* `visitor-email-limit-burst` is the initial bucket of emails each visitor has. This defaults to 16.
|
||||
* `visitor-email-limit-replenish` is the rate at which the bucket is refilled (one email per x). Defaults to 1h.
|

|
||||
During normal usage, you shouldn't encounter these limits at all, and even if you burst a few requests or emails
|
||||
(e.g. when you reconnect after a connection drop), it shouldn't have any effect.
|
||||
|
||||
## Tuning for scale
|
||||
If you're running ntfy for your home server, you probably don't need to worry about scale at all. In its default config,
|
||||
if it's not behind a proxy, the ntfy server can keep about **as many connections as the open file limit allows**.

|

## Attachments
|
||||
You can **send images and other files to your phone** as attachments to a notification. The attachments are then downloaded
|
||||
onto your phone (depending on size and setting automatically), and can be used from the Downloads folder.
|
||||
|
||||
There are two different ways to send attachments:
|
||||
|
||||
* sending [a local file](#attach-local-file) via PUT, e.g. from `~/Flowers/flower.jpg` or `ringtone.mp3`
|
||||
* or by [passing an external URL](#attach-file-from-a-url) as an attachment, e.g. `https://f-droid.org/F-Droid.apk`
|
||||
|
||||
### Attach local file
|
||||
To **send a file from your computer** as an attachment, you can send it as the PUT request body. If a message is greater
|
||||
than the maximum message size (4,096 bytes) or consists of non UTF-8 characters, the ntfy server will automatically
|
||||
detect the mime type and size, and send the message as an attachment file. To send smaller text-only messages or files
|
||||
as attachments, you must pass a filename by passing the `X-Filename` header or query parameter (or any of its aliases
|
||||
`Filename`, `File` or `f`).
|
||||
|
||||
By default, and how ntfy.sh is configured, the **max attachment size is 15 MB** (with 100 MB total per visitor).
|
||||
Attachments **expire after 3 hours**, which typically is plenty of time for the user to download it, or for the Android app
|
||||
to auto-download it. Please also check out the [other limits below](#limitations).

### Attach file from a URL
|
||||
Instead of sending a local file to your phone, you can use **an external URL** to specify where the attachment is hosted.
|
||||
This could be a Google Drive or Dropbox link, or any other publicly available URL. The ntfy server will briefly probe
|
||||
the URL to retrieve type and size for you. Since the files are externally hosted, the expiration or size limits from
|
||||
above do not apply here.
|
||||
|
||||
To attach an external file, simple pass the `X-Attach` header or query parameter (or any of its aliases `Attach` or `a`)
|
||||
to specify the attachment URL. It can be any type of file. Here's an example showing how to upload an image:

you'd like to persist longer, or to blast-notify yourself on all possible channels.

### UnifiedPush
|
||||
!!! info
|
||||
This setting is not relevant to users, only to app developers and people interested in [UnifiedPush](https://unifiedpush.org).
|
||||
|
||||
[UnifiedPush](https://unifiedpush.org) is a standard for receiving push notifications without using the Google-owned
|
||||
[Firebase Cloud Messaging (FCM)](https://firebase.google.com/docs/cloud-messaging) service. It puts push notifications
|
||||
in the control of the user. ntfy can act as a **UnifiedPush distributor**, forwarding messages to apps that support it.
|
||||
|
||||
When publishing messages to a topic, apps using ntfy as a UnifiedPush distributor can set the `X-UnifiedPush` header or query
|
||||
parameter (or any of its aliases `unifiedpush` or `up`) to `1` to [disable Firebase](#disable-firebase). As of today, this
|
||||
option is equivalent to `Firebase: no`, but was introduced to allow future flexibility.

|
||||
There are a few limitations to the API to prevent abuse and to keep the server healthy. Almost all of these settings
|
||||
are configurable via the server side [rate limiting settings](config.md#rate-limiting). Most of these limits you won't run into,
|
||||
but just in case, let's list them all:
|
||||
|
||||
| Limit | Description |
|
||||
|---|---|
|
||||
| **Message length** | Each message can be up to 4096 bytes long. Longer messages are truncated. |
|
||||
| **Requests** | By default, the server is configured to allow 60 requests at once, and then refills the your allowed requests bucket at a rate of one request per 10 seconds. You can read more about this in the [rate limiting](config.md#rate-limiting) section. |
|
||||
| **E-mails** | By default, the server is configured to allow sending 16 e-mails at once, and then refills the your allowed e-mail bucket at a rate of one per hour. You can read more about this in the [rate limiting](config.md#rate-limiting) section. |
|
||||
| **Subscription limits** | By default, the server allows each visitor to keep 30 connections to the server open. |
|
||||
| **Total number of topics** | By default, the server is configured to allow 5,000 topics. The ntfy.sh server has higher limits though. |
|
||||
|---------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| **Message length** | Each message can be up to 4,096 bytes long. Longer messages are treated as [attachments](#attachments). |
|
||||
| **Requests** | By default, the server is configured to allow 60 requests per visitor at once, and then refills the your allowed requests bucket at a rate of one request per 10 seconds. |
|
||||
| **E-mails** | By default, the server is configured to allow sending 16 e-mails per visitor at once, and then refills the your allowed e-mail bucket at a rate of one per hour. |
|
||||
| **Subscription limit** | By default, the server allows each visitor to keep 30 connections to the server open. |
|
||||
| **Attachment size limit** | By default, the server allows attachments up to 15 MB in size, up to 100 MB in total per visitor and up to 5 GB across all visitors. |
|
||||
| **Attachment expiry** | By default, the server deletes attachments after 3 hours and thereby frees up space from the total visitor attachment limit. |
|
||||
| **Attachment bandwidth** | By default, the server allows 500 MB of GET/PUT/POST traffic for attachments per visitor in a 24 hour period. Traffic exceeding that is rejected. |
|
||||
| **Total number of topics** | By default, the server is configured to allow 15,000 topics. The ntfy.sh server has higher limits though. |
