Hookshot can bridge [Webhooks](https://en.wikipedia.org/wiki/Webhook) from software project management services such as GitHub, GitLab, JIRA, and Figma, as well as generic webhooks.
See the project's [documentation](https://matrix-org.github.io/matrix-hookshot/latest/hookshot.html) to learn what it does in detail and why it might be useful to you.
Note: the playbook also supports [matrix-appservice-webhooks](configuring-playbook-bridge-appservice-webhooks.md), which however is soon to be archived by its author and to be replaced by hookshot.
1. Enable the bridge by adding `matrix_hookshot_enabled: true` to your `vars.yml` file
2. For each of the services (GitHub, GitLab, Jira, Figma, generic webhooks) fill in the respective variables `matrix_hookshot_service_*` listed in [main.yml](/roles/matrix-bridge-hookshot/defaults/main.yml) as required.
3. Take special note of the `matrix_hookshot_*_enabled` variables. Services that need no further configuration are enabled by default (GitLab, Generic), while you must first add the required configuration and enable the others (GitHub, Jira, Figma).
4. If you're setting up the GitHub bridge, you'll need to generate and download a private key file after you created your GitHub app. Copy the contents of that file to the variable `matrix_hookshot_github_private_key` so the playbook can install it for you, or use one of the [other methods](#manage-github-private-key-with-matrix-aux-role) explained below.
5. If you've already installed Matrix services using the playbook before, you'll need to re-run it (`--tags=setup-all,start`). If not, proceed with [configuring other playbook services](configuring-playbook.md) and then with [Installing](installing.md). Get back to this guide once ready. Hookshot can be set up individually using the tag `setup-hookshot`.
Other configuration options are available via the `matrix_hookshot_configuration_extension_yaml` and `matrix_hookshot_registration_extension_yaml` variables, see the comments in [main.yml](/roles/matrix-bridge-hookshot/defaults/main.yml) for how to use them.
Create a room and invite the Hookshot bot (`@hookshot:DOMAIN`) to it.
Make sure the bot is able to send state events (usually the Moderator power level in clients).
Send a `!hookshot help` message to see a list of help commands.
Refer to [Hookshot's documentation](https://matrix-org.github.io/matrix-hookshot/latest/usage.html) for more details about using the brige's various features.
**Important:** Note that the different listeners are bound to certain paths which might differ from those assumed by the hookshot documentation, see [URLs for bridges setup](#urls-for-bridges-setup) below.
| metrics | `/metrics/hookshot` | `matrix_hookshot_metrics_enabled` and `matrix_hookshot_metrics_proxying_enabled`. Requires `/metrics/*` endpoints to also be enabled via `matrix_nginx_proxy_proxy_matrix_metrics_enabled` (see the `matrix-nginx-proxy` role). Read more in the [Metrics section](#metrics) below. | Prometheus |
See also `matrix_hookshot_matrix_nginx_proxy_configuration` in [init.yml](/roles/matrix-bridge-hookshot/tasks/init.yml).
The different listeners are also reachable *internally* in the docker-network via the container's name (configured by `matrix_hookshot_container_url`) and on different ports (e.g. `matrix_hookshot_appservice_port`). Read [main.yml](/roles/matrix-bridge-hookshot/defaults/main.yml) in detail for more info.
- copy the *contents* of the downloaded file and set the variable `matrix_hookshot_github_private_key` to the contents (see example in [main.yml](/roles/matrix-bridge-hookshot/defaults/main.yml)).
- somehow copy the file to the path `{{ matrix_hookshot_base_path }}/{{ matrix_hookshot_github_private_key_file }}` (default: `/matrix/hookshot/private-key.pem`) on the server manually.
- use the `matrix-aux` role to copy the file from an arbitrary path on your ansible client to the correct path on the server.
To use `matrix-aux`, make sure the `matrix_hookshot_github_private_key` variable is empty. Then add to `matrix-aux` configuration like this:
The provisioning API will be enabled automatically if you set `matrix_dimension_enabled: true` and provided a `matrix_hookshot_provisioning_secret`, unless you override it either way. To use hookshot with dimension, you will need to enter as "Provisioning URL": `http://matrix-hookshot:9002`, which is made up of the variables `matrix_hookshot_container_url` and `matrix_hookshot_provisioning_port`.
Metrics are **only enabled by default** if the builtin [Prometheus](configuring-playbook-prometheus-grafana.md) is enabled (by default, Prometheus isn't enabled). If so, metrics will automatically be collected by Prometheus and made available in Grafana. You will, however, need to set up your own Dashboard for displaying them.
To explicitly enable metrics, use `matrix_hookshot_metrics_enabled: true`. This only exposes metrics over the container network, however.
**To collect metrics from an external Prometheus server**, besides enabling metrics as described above, you will also need to:
- enable the `https://matrix.DOMAIN/metrics/*` endpoints on `matrix.DOMAIN` using `matrix_nginx_proxy_proxy_matrix_metrics_enabled: true` (see the `matrix-nginx-role` or [the Prometheus and Grafana docs](configuring-playbook-prometheus-grafana.md) for enabling this feature)
- expose the Hookshot metrics under `https://matrix.DOMAIN/metrics/hookshot` by setting `matrix_hookshot_metrics_proxying_enabled: true`
If you are also running [matrix-appservice-webhooks](configuring-playbook-bridge-appservice-webhooks.md), it reserves its namespace by the default setting `matrix_appservice_webhooks_user_prefix: '_webhook_'`. You should take care if you modify its or hookshot's prefix that they do not collide with each other's namespace (default `matrix_hookshot_generic_user_id_prefix: '_webhooks_'`).
