403 on Webhook

I'm having issues getting my web hook to work. On Caddy start it does pull the latest code from bitbucket as expected. But for some reason pulling using the webhook is not working. I'm thinking that the webhook should never reach the rewrite rule, no? The key file should be working because it is pulling on container start, just not on code push.

Any help would be much appreciated. Here is my info:
## CADDYFILE VERSION 0.8.2:

```
mydomain
tls myemail
#browse
fastcgi / 127.0.0.1:9000 php # php variant only
startup php-fpm # php variant only

git {
repo git@bitbucket.org:mygitrepo.git
branch master
key /root/.ssh/id_rsa
path ../../src
hook /_webhook
then cp -pR /srv/src/laravel /srv/
then sh -c "cd /srv/laravel && composer update"
then sh -c "cd /srv && chown -R nobody.nobody laravel"
}

root /srv/laravel/public

log access.log
errors error.log

rewrite {

to {path} {path}/ /index.php?{query}
}
```
