Integrations

Apprise API is meant to be a single notification gateway. Instead of building direct webhooks to Discord, Slack, email, and SMS in every project, send to Apprise API and let it route the message.

Endpoints

Note

Apprise does not require you to add Python in your application.
Apprise itself is written in Python, but most integrations interact with it purely over HTTP using the Apprise API. Applications in any language can send notifications without embedding Python or managing notification logic locally.

If you want to…	Recommended Approach
Avoid embedding Python in your application	Apprise API (Stateful or Stateless)
Keep notification logic out of your codebase	Apprise API (Stateful)
Use Apprise as a simple HTTP gateway	Apprise API (Stateless)
Send notifications from scripts or the command line	Apprise CLI or Apprise Python Library

Stateless

If you cannot (or do not want to) store configuration server-side, you can also use stateless notifications:

• POST /notify

Stateless calls include the destination Apprise URLs in the request payload.

See the endpoint reference for the full list of supported paths.

Stateful

For stateful notifications (recommended for most integrations), you call one endpoint:

• POST /notify/{KEY}

Where {KEY} identifies a configuration saved on the server. Your client code stays small and stable, while the Apprise API instance holds the actual notification URLs and any routing tags.

Build the Request URL

Given:

• scheme: http or https
• host: the Apprise API hostname or IP
• port: optional, omit for 80 (http) or 443 (https)
• key: your saved configuration key

Construct:

• BASE = {scheme}://{host}
• If a non-default port is used: BASE = {scheme}://{host}:{port}
• NOTIFY = {BASE}/notify/{key}

Note

If your Apprise API is hosted behind a reverse proxy under a subpath, you may need to prefix your base URL with that path (for example, https://example.com/apprise).

Common Payload Fields

Apprise API accepts both form and JSON payloads in many cases. For integrations, JSON is usually easiest.

• body (required): message content
• title (optional): message title
• type (optional): info (default), success, warning, or failure
• format (optional): text (default), markdown, or html
• tag (optional, stateful): route to a subset of saved URLs

Tags

Tags are only meaningful for stateful calls (/notify/{KEY}), because the server already knows which URLs belong to that key.

Tag matching logic:

• Space, +, or & means AND (intersection)
• Comma or | means OR (union)

Examples:

• "devops,admin" notifies URLs tagged devops OR admin
• "devops critical" notifies URLs tagged devops AND critical

Attachments

To send attachments, use multipart/form-data.

• Use attach (recommended) or attachment as the field name
• The attachment value can be:
  • a local file upload
  • a remote URL that Apprise API downloads and forwards

Payload Mapping Hooks

If a third-party tool cannot change its JSON keys, Apprise API can map incoming fields to Apprise fields using query parameters.

Syntax:

• ?:incoming_field=apprise_field

Example:

• A tool sends {"message": "Server Down"}
• Map it to Apprise body with ?:message=body

See the API usage documentation for more details.

Examples

Stateless Examples

curl

# Minimal stateless notification using curl
curl -X POST "http://localhost:8000/notify" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": [
      "discord://TOKEN/CHANNEL",
      "mailto://user:pass@example.com"
    ],
    "body": "Hello from Apprise (stateless)"
  }'

# Stateless notification with an attachment
curl -X POST "http://localhost:8000/notify" \
  -F 'payload={
    "urls": ["discord://TOKEN/CHANNEL"],
    "title": "Build Complete",
    "body": "Artifact attached"
  };type=application/json' \
  -F "attach=@/path/to/file.txt"

Python

Note

The first example uses requests for synchronous calls. The second example uses aiohttp for async workflows and also shows multipart attachments.

The following leverages the requests library:

python_requests_example.py

from __future__ import annotations

    def notify_url(self) -> str:
        origin = f"{self.scheme}://{self.host}:{self.port}" if self.port else f"{self.scheme}://{self.host}"
        prefix = self.base_path.strip("/")
        path = f"/{prefix}/notify/" if prefix else f"/notify/"
        return f"{origin}{path}"

api = AppriseStatelessApi(scheme="http", host="localhost", port=8000)
payload = {
    "urls": ["discord://TOKEN/CHANNEL", "mailto://user:pass@example.com"],

resp = requests.post(
    api.notify_url,
    json=payload,
    headers={"Accept": "application/json"},
    timeout=30,
)
resp.raise_for_status()

# An attachment example:

files = {
    "attach": open("/path/to/file.txt", "rb")
}
payload = {
    "urls": "discord://TOKEN/CHANNEL,mailto://user:pass@example.com",
    "body": "Artifact attached"

    json=payload,

The following leverages the aiohttp library:

        return f"{origin}{path}"


async def apprise_notify_json(url: str, payload: dict[str, Any]) -> None:

    async with aiohttp.ClientSession(timeout=timeout, headers={"Accept": "application/json"}) as session:
        async with session.post(url, json=payload) as resp:
            resp.raise_for_status()


async def apprise_notify_with_attachment(url: str, body: str, file_path: str) -> None:
    path = Path(file_path)
    form = aiohttp.FormData()
    form.add_field("body", body)
    # Field name can be attach or attachment
    form.add_field("attach", path.read_bytes(), filename=path.name)

    timeout = aiohttp.ClientTimeout(total=60)
    async with aiohttp.ClientSession(timeout=timeout, headers={"Accept": "application/json"}) as session:
        async with session.post(url, data=form) as resp:
            resp.raise_for_status()


# Usage:

# Send our notification:
asyncio.run(apprise_notify_json(api.notify_url, {"body": "Hello"}))

# Send our notification with an attachment:

Stateful Examples

curl

# JSON payload (recommended)
SCHEME=http
HOST=localhost
PORT=8000
KEY=my-alerts

BASE="$SCHEME://$HOST"
if [ ! -z "$PORT" ]; then
   BASE="$SCHEME://$HOST:$PORT"
fi
URL="$BASE/notify/$KEY"

curl -X POST \
  -F "title=Build" \
  -F "type=success" \
  -F "body=Build complete" \
  "$URL"

Note

The above could have also been written like this:

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{"title":"Build","body":"Build complete","type":"success"}' \
  "$URL"

Here is another example tha routes based on defined tags:

curl -X POST \
  -F "type=warning" \
  -F "tag=devops critical" \
  -F "body=Disk space low" \
  "$URL"

Note

The above could have also been written like this:

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{"tag":"devops critical","body":"Disk space low","type":"warning"}' \
  "$URL"

# Attachment (multipart)
curl -X POST \
  -F "body=See attached log" \
  -F "attach=@/var/log/syslog" \
  "$URL"

Python

Note

The first example uses requests for synchronous calls. The second example uses aiohttp for async workflows and also shows multipart attachments.

The example uses reqwest, serde, tokio, and urlencoding crates. If you prefer fewer dependencies, you can do the same POST with hyper or ureq.
