Note: This bridge is no longer maintained. While not a 1:1 replacement, the bridge's author suggests taking a look at [matrix-hookshot](https://github.com/Half-Shot/matrix-hookshot) as a replacement, which can also be installed using [this playbook](configuring-playbook-bridge-hookshot.md).
3. As of Synapse 1.90.0, you will need to add the following to `matrix_synapse_configuration_extension_yaml` to enable the [backwards compatibility](https://matrix-org.github.io/synapse/latest/upgrade#upgrading-to-v1900) that this bridge needs:
```yaml
matrix_synapse_configuration_extension_yaml: |
use_appservice_legacy_authorization: true
```
*Note*: This deprecated method is considered insecure.
4. 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.
5. If you're using the [Dimension Integration Manager](configuring-playbook-dimension.md), you can configure the Webhooks bridge by opening the Dimension integration manager -> Settings -> Bridges and selecting edit action for "Webhook Bridge". Press "Add self-hosted Bridge" button and populate "Provisioning URL" & "Shared Secret" values from `/matrix/appservice-webhooks/config/config.yaml` file's homeserver URL value and provisioning secret value, respectively.
