Inputs
| Input | Type | How to use it |
|---|---|---|
| Account | Account | Choose a saved Slack connector from this organization. Create or reconnect it in Settings > Connectors. Do not enter an API key, password or email address here. |
| Channel | slack channel | Select the Slack channel or supply its ID, such as C0123456789. A channel name or # prefix is not the ID. |
| Message Text | text box | Text to post, using Slack's formatting and mention rules. This field does not send attachments or a blocks object. |

| Bot Name | text | Optional display name when sending as a bot. Slack may require customization permission. Ignored when sending as a user. |

Errors and limits
The posting identity needs channel access and chat-write permission. Invite the bot manually if necessary. Inspect the channel before retrying an uncertain result to avoid duplicate messages. Reconnect the matching app in Settings if the connection is unavailable. Check the resource IDs and required read or edit permissions. Wait after provider rate limiting. Use live data is required; isolated tests and live debugging cannot contact these services. Provider requests time out after 30 seconds. Slack responses are limited to 2 MiB.

Account: choose your Slack connector. User: U0123456789; Message Text: Your report is ready; Send As Bot: true; Bot Name: empty.
Errors and limits
Check the user ID and permission to open direct conversations and send messages. An uncertain retry can send the message twice.

|---|---|---|
| Account | Account | Choose a saved Slack connector from this organization. Create or reconnect it in Settings > Connectors. Do not enter an API key, password or email address here. |

| Reminder Text | text box | The reminder text, such as Review the draft before publishing. |
| Remind When | text | A time accepted by Slack, such as in 2 hours, tomorrow at 9am, or a supported timestamp. Slack controls interpretation and supported formats. |

Example
Account: choose your Slack connector. Remind Who: U0123456789; Reminder Text: Review the draft; Remind When: in 2 hours.
Errors and limits
This uses the bot token. Slack may reject it for missing reminder permissions or an unsupported token type. If the workspace disallows it, use a supported Slack-native reminder workflow.

Use live data is required; isolated tests and live debugging cannot contact these services. Provider requests time out after 30 seconds. Slack responses are limited to 2 MiB.
Create a public or private Slack channel.
Inputs
| Input | Type | How to use it |
|---|---|---|
| Account | Account | Choose a saved Slack connector from this organization. Create or reconnect it in Settings > Connectors. Do not enter an API key, password or email address here. |
| Channel Name | text | A new channel name, such as customer-updates. Follow Slack naming rules and avoid an existing channel name. |
| Private | yes no | False creates a public channel using the bot identity; true creates a private channel using the authorized user identity. The selected identity needs permission to create that channel type. |
Result
An object with ok: true, channelId and channelName. Slack can normalize the final channel name.
Example
Account: choose your Slack connector. Channel Name: customer-updates; Private: false.
Errors and limits

|---|---|---|
| Account | Account | Choose a saved Slack connector from this organization. Create or reconnect it in Settings > Connectors. Do not enter an API key, password or email address here. |
| Cursor | text | Leave empty for the first page. For later pages, pass response_metadata.next_cursor unchanged. Do not use a page number. |

Slack's page object with channels and response_metadata.next_cursor. The list can be empty. A nonempty cursor means another page exists; an empty cursor means the end.
Example

Errors and limits

Read one page of messages from a channel accessible to the bot.
Inputs
| Input | Type | How to use it |
|---|---|---|
| Account | Account | Choose a saved Slack connector from this organization. Create or reconnect it in Settings > Connectors. Do not enter an API key, password or email address here. |
| Channel | text | Select the Slack channel or supply its ID, such as C0123456789. A channel name or # prefix is not the ID. |

Errors and limits
The bot needs channel membership and history-read permission. Wait after rate limiting, then continue with the returned cursor.

Use live data is required; isolated tests and live debugging cannot contact these services. Provider requests time out after 30 seconds. Slack responses are limited to 2 MiB.
Isolated tests and live debugging do not call connected providers. Enable Use live data only when you intend to contact the account. Writes, messages and AI requests can change real data or incur provider charges. A successful connection check does not prove access to every action. These examples explain the command contract; they are not evidence of a completed live provider request.
