[Feature Request] Custom Headers and Payload Mapping For Custom Notifications

[OthmanHaba]

What problem will this feature address?

Description: I would like to request an enhancement to the Webhook Notification system to allow connecting to custom internal services more easily.

Current Behavior: Currently, the Webhook notification sends a fixed JSON payload to a specified URL. There is no option to define custom headers or inject specific key-value pairs (such as a channel_id or custom_token) that my proprietary service requires.

Desired Behavior: I propose adding a "Custom Data" or "Headers" section to the Webhook configuration form.

Option A (Headers): Allow users to add custom HTTP headers (e.g., X-Channel-ID: 12345 or Authorization: Bearer ).

Option B (Custom Payload/Key-Value): Allow users to define key-value pairs that get merged into the JSON payload.

Example: If I add channel: "my-ops-team", the final JSON sent by Dokploy would include "channel": "my-ops-team" alongside the standard deployment data.

Use Case: I am running a custom notification service that routes messages to specific internal channels based on a key-value pair in the payload. Without this, I have to build a middleware just to transform Dokploy's webhooks into a format my service accepts.
