You can configure Go-Matrix-Webhook using the following environment variables:

• LISTEN_ADDR: The address on which the webhook server listens (default: "0.0.0.0").
• LISTEN_PORT: The port on which the webhook server listens (default: 8080).
• LISTEN_PATH: The path on which the webhook server listens (default: "/").
• SECRET_HEADER: Pre-shared X-Secret security header.
• MATRIX_ACCESS_TOKEN: The access token for your Matrix account.
• MATRIX_ID: Your Matrix user ID.

Alternatively, you can set these options using command-line flags. Run ./go-matrix-webhook --help for more information.

Usage

Create access token

curl -X POST -H "Content-Type: application/json" -d '{"type": "m.login.password", "identifier": {"type": "m.id.user", "user": "<bot username>"}, "password": "<bot password>", "initial_device_display_name": "Webhook Client"}' "https://<your-server>/_matrix/client/r0/login"

Get the access_token from the curl output and pass it into this application along with other required variables. Don't forget to add the bot to your room!

Send Messages

To send a message, simply make a POST request with the following structure:

curl -X POST -H 'X-Secret: <your_secret_header>' -H "Content-Type: application/json" -d '{"message": "<your_message>", "room_id": "<your_room_id>"}' "http://<your_webhook_server>:<your_webhook_port>"

Replace <your_secret_header>, <your_message>, <your_room_id>, <your_webhook_server>, and <your_webhook_port> with the appropriate values.
