Webhooks over Telegram (WoT)

⚠ This project is currently being migrated over the new stack. The main branch is completely unstable and which builds are, probably, even not working.

WoT aims to provide a simple API for registering webhooks and sending messages to Telegram chats via them using a single secret URL. Just like in Discord or Slack. You simply POST a message to chats:

POST https://wot.example.com/<nonce>
Content-Type: application/json
Authorization: auth token

{
  "content": {
    "sources": [
      {
        "type": "REGULAR",
        "value": "Hello, world!",
        "subsources": []
      }
    ]
  }
}

Running

To run the server you should have Java 17+ and Docker Compose installed.

Build the image:

./gradlew wot-server:bootBuildImage

Edit the docker-compose.yml file and configure the secret key used for authorization:

# ./wot-server/docker/docker-compose.yml
# ...
services:
  # ...
  wot-server:
    # ...
    environment:
      # ...
      SIMPLE_SECURITY_AUTHENTICATION_SECRET: my_secret_key
      # ...
    # ...
  # ...
# ...

Run the containers:

docker-compose -f ./wot-server/docker/docker-compose.yml up -d

Usage

Let's start with creating a webhook:

POST https://localhost:9696/api/webhooks
Content-Type: application/json
Authorization: ...

{
  "name": "my-webhook",
  "botToken": "your bot token",
  "private": true,
  "targets": []
}

Now open the Telegram bot with which the webhook is bound and send /subscribe.

Since this webhook is marked as private, we have to send its nonce which we got in the response.

Well, let's send a message now:

POST https://localhost:9696/<webhook nonce>
Content-Type: application/json

{
  "content": {
    "sources": [
      {
        "type": "REGULAR",
        "value": "Hello, world!",
        "subsources": []
      }
    ]
  }
}

Authorization

Each request to /api/** path must include a secret key within the Authorization header. See Running for more info.
