 | --------- | ---- | -------- | ----------- |
-| `signingSecret` | string | Yes | The signing secret from your Slack app to validate request authenticity. |
-| `botToken` | string | No | The bot token from your Slack app. Required for downloading files attached to messages. |
-| `includeFiles` | boolean | No | Download and include file attachments from messages. Requires a bot token with files:read scope. |
-| `setupWizard` | modal | No | Walk through manifest creation, app install, and pasting credentials. |
+| `eventType` | string | Yes | The single Slack event this trigger fires on. Add another trigger block for another event. |

+| `manualBotCredential` | string | Yes | Set the custom bot credential ID directly. |
+| `source` | string | No | Restrict to direct messages, public channels, or private channels. Leave empty to match any. |
+| `channelFilter` | channel-selector | No | Restrict to specific channels. Leave empty to trigger on any channel the bot has been added to. |

 Your deployment must also be reachable from the provider's servers for webhook triggers to fire — a Sim instance on a private network can use polling triggers but not webhook triggers. Polling triggers additionally require the scheduler; see [Background Jobs](/platform/self-hosting/background-jobs).
