Include Linear

[jsfour]

We currently support github webhooks, but we also need to support webhooks from Linear. Here is where the github webhook is defined: https://github.com/octaviuslabs/walter/blob/main/src/index.ts#L16

To add Linear webhook support, we will need to create a new endpoint in your express app specifically for Linear. We will also need to validate the incoming requests to ensure they are coming from Linear.

Here's a basic pseudocode approach:

// import necessary packages
import express from 'express';
import bodyParser from 'body-parser';
import { verifyLinearWebhook } from './verifyLinearWebhook'; // This is a custom function you would need to create

// initialize express app
const app = express();

// use body-parser middleware to parse incoming JSON
app.use(bodyParser.json());

// existing GitHub webhook
app.post('/github-webhook', (req, res) => {
    // existing code for GitHub webhook
});

// new Linear webhook
app.post('/linear-webhook', (req, res) => {
    // validate request
    if (!verifyLinearWebhook(req)) {
        return res.status(403).json({ error: 'Invalid signature' });
    }
    
    // handle valid Linear webhook request
    // this would depend on your specific use case
    handleLinearWebhook(req.body);

    // send response
    return res.status(200).json({ message: 'Webhook received' });
});

// start server
app.listen(PORT, () => Log.info(`Server listening on port ${PORT}`));

In the above pseudocode, the verifyLinearWebhook function is a placeholder for your own implementation of Linear webhook verification. This function should take the request as input, verify the request signature according to Linear's specifications, and return a boolean indicating whether the request is valid.

The handleLinearWebhook function is also a placeholder for your own implementation of handling the webhook request. This function should take the request body as input, which will contain the webhook event data from Linear.
