Your experience while developing next generation Slack apps is largely governed by the SDKs and the CLI. These tools change as the platform changes, and we release new versions regularly. Subscribe to be notified of updates, and let us know how we're doing.
trigger info now also shows who can run the trigger.--no-color flag, which removes all ANSI sequences for color as well
as emojis, giving you plain text output from the CLI that's perfect for piping
to a text file.datastore query command now supports a cursor argument to help you
paginate your results the way you want.Today we're announcing that the next generation Slack platform–which provides a faster, more flexible way to build automations on top of Slack–is generally available to developers. The platform's overhauled architecture gives developers more ways to build, code, and ship custom apps and workflows more quickly and easily in an environment that's both secure and compliant. Read the announcement or follow the Quickstart to get started today!
CLI enhancements
login flow instructions to be clearer for new developers.trigger_execution log for greater readability.slack doctor command to display the local git version.slack help command, but not to worry! Those hidden commands are still visible while using slack help -v.Bug fixes
slack help deno without any other arguments.--verbose flag.create experience for developers from installation to deployment.trigger create or trigger list for developers to invite their app to a channel to receive events, and formatted outputs when displaying trigger information.message_limit_exceeded. The error code is included in the following endpoints when a free team has reached their message limit: callbacks.chat/postMessage, chat/postEphemeral, chat/postMessage, chat/scheduleMessage, chat/shareMessage, files/share, and drafts/create. For more information, refer to Usage limits for free workspaces.slack cloud command to the slack platform command. For more information, refer to commands.(dev) with (local) for local apps in the workspace list.slack workspace uninstall command to slack workspace delete.slack login --auth <string> to log in.-a for the --app flag.slack auth info command, as the pertinent information is found by using the slack auth list command.slack samples command, which will list the available sample app templates you can use to create a new app.CLI updates
open-form-response export command, which generates a CSV of OpenForm responses.--app <id|env> flag, which replaces the --local-run flag.Other enhancements
function_runtime to be undefined instead of slack.local (from dev).New functionality
datastore update command. Where the put datastore command replaces the entire record (matching what you might expect from an HTTP PUT call), the new update command allows for field-level changes, leaving unspecified properties unchanged (matching what you might expect from an HTTP PATCH call).slack.json with the config.trigger-paths property.trigger create or trigger update now provides a file selection prompt when no file is specified.deploy, run, or env commands, you can now use the --workspace (-w) flag to specify a target workspace. If omitted, the CLI will prompt you to select from your currently authorized workspaces. Ensure your app is authorized into your target workspace with slack auth list; if you don't see your target workspace, create a new authorization with slack login.Enhancements
activity command now formats workflow_bot_invited event types.external-auth remove command.invalid_challenge error.deploy and run commands. The upcoming breaking changes are outlined at the end of this changelog.create command to better focus on next steps.Upcoming maintenance window
On March 13th, 2023, between 1pm and 5pm PST, we'll be making some security improvements behind-the-scenes on our end; no action is required from you. During this time, you may experience some lag or downtime with your Run on Slack functions.
Upcoming breaking changes
The following breaking changes will ship April 6, 2023. Before April 6th, please update your app in accordance with the changes outlined below to ensure that it continues to work as expected.
Third-party authentication
credential_source property to specify which user’s token should be selected or requested during workflow execution. For example:// OLD
const sampleFunctionStep = SampleWorkflow.addStep(SampleFunctionDefinition, {
user: SampleWorkflow.inputs.user,
googleAccessTokenId: {},
});
// NEW
const sampleFunctionStep = SampleWorkflow.addStep(SampleFunctionDefinition, {
user: SampleWorkflow.inputs.user,
googleAccessTokenId: {
credential_source: "DEVELOPER" // Add this by April 6th, 2023
},
});
Datastores
datastore:read and datastore:write scopes will no longer be auto added to your app manifest botScopes.apps.datastore.put method will now overwrite the entire datastore item instead of only overwriting the individual fields included in the call. Use apps.datastore.update to overwrite individual fields.primary_key is the only required attribute, all other attributes will be treated as optional. Unhandled optional attributes may cause TypeScript errors in your code. If you'd like to migrate to optional attributes ahead of time, you can cast a DatastoreItem:import { DatastoreItem } from "deno-slack-api/types.ts";
const response = await client.apps.datastore.get<typeof SampleObjectDatastore.definition>({
datastore: "SampleObjects",
id: sampleObject,
},
);
const item = resp.item as DatastoreItem<
typeof SampleObjectDatastore.definition
>;
resp.item.original_msg // is still required, but
item.original_msg // is now optional
Interactivity payloads
response_url property will no longer be included in Block Kit interactivity action & view_submission payloads that are routed to function handlers. The Slack API client provided to these handlers can call Slack’s messaging APIs directly.Slack functions
ReplyInThread function provides a new way to reply to messages in thread. Instead of passing the message you want to reply to as the thread_ts input parameter of SendDM or SendMessage, now you can pass that message into the message_context input parameter of the ReplyInThread function.InviteUserToChannel has two new optional input parameters: user_ids, an array of user IDs, and channel_ids, an array of (you guessed it) channel IDs. The single value versions, user_id and channel_id, will be removed on April 6th, 2023.AddUserToUsergroup and RemoveUserFromUserGroup have one new optional input parameter: user_ids, an array of user IDs. The user_id input will be removed.Slack CLI
slack that you may have in your system.slack logout now revokes auth and refresh tokens.slack run, slack deploy, or slack collaborator list prompt only for your workspace choice and then select the environment automatically depending on the command.Trigger updates
slack deploy, a prompt to generate a trigger from a trigger definition file will appear if no triggers exist in this environment.slack triggers list, each trigger's creation and last updated times are now included.workflow_not_found.Other changes
DefineProperty object wrapper to bring accurate typing to nested object properties and parameters.message_ts and message_context types were added to the Deno Slack SDK for stronger typing when handling messages.email and url now exist on the Slack.types.string type, helping validate the inputs of function, forms, and workflows.client.apps.external.auth.get method was added to the Deno Slack API for fetching external auth tokens with typeahead support.Important changes
outgoingDomains property of your app's manifest.slack login and paste the /slackauthticket command into your workspace, instead of directly sending you back to the CLI, Slack will issue a verification code in the Slack client which you need to input into your CLI before you can complete the login. This does not break login for older versions. Additionally, existing logins in your credentials.json file are not affected.Other changes
slack run command, you will be prompted to generate a trigger. This prompt will not occur when running slack deploy.schema_compatibility_error on datastores_deleted.datastore command help text to be consistent with website documentation.channel_id to grant or revoke access to triggers.datastore command examples to not require the app_id parameter, as the App Selector Prompt automatically adds the app_id to the query.slack env add and slack env remove, instead of receiving a pesky error. When slack env add prompts for the secret value, it uses a password-like input to hide the input value from the terminal screen to remove possible leakages of these values from the terminal history.slack create to create from a template if Git is not installed.channel_not_found error.Enhancements
install and deploy commands to use the selected workspace token.get and delete datastore methods to use id instead of the name of the primary_keyEnhancements
slack uninstall command, you will now receive a warning message confirming that all of the data related to this app will also be deleted (i.e. the app's related workflows, functions, and datastores). See update here.slack manifest validate --verbose, you are now prompted to choose an AppID. This change fixes a bug where an app manifest may have previously been validated against an incorrect AppID. Since each app may have a slightly different manifest depending on what stage of development it's in (for example, a local development app vs. a deployed app), you can now specify the app to validate your local project's manifest against.<email and user_id> flag that adds or removes a user directly, e.g. slack collaborator add U123456789 or slack collaborator add iuseslack@mycompany.com.slack create and choose our Scaffolded app to familiarize yourself more closely with datastores on the new Slack platform.Breaking change
Beginning January 26th, 2023, you must specify all domains you'll use for remote HTTP requests in the outgoingDomains property of your app's manifest. outgoingDomains will be enforced on all workspaces for Slack-hosted apps. Previously, outgoingDomains was only enforced on workspaces with Admin-Approved Apps enabled.
When does this happen?
outgoingDomains will be enforced on all workspaces for Slack-hosted apps.hooks.slack.com was being implicitly added as an approved outgoing domain on AAA-enabled workspaces. After January 19th, 2023, it will be removed from that list and will need to be added explicitly as an outgoing domain if your functions make network requests to hooks.slack.com.How should I get ready?
deno-slack-hooks dependency to v0.7.0, the slack run command will enforce your app's outgoingDomains setting locally.slack run. If you recieve a "Requires net access to <domain_name>" error message, add the listed domain to your outgoingDomains setting and try again. Once you're done, redeploy it using the command slack deploy.Other changes
AO12345678 instead of text, e.g. Status: Installed.slack manifest validate no longer throws requires_request_url or requires_socket_mode_enabled errors when validating the Hello World starter template manifest.Enhancements
slack workspace default command.enterprise_id as a parameter to application functions (and their interactivity handlers) in the deno-slack-sdk. See all available function context parameters here.placeholder text for the following Block Kit elements: channels_select, conversations_select, multi_channels_select, multi_users_select, and users_select.Enhancement

slack trigger info command to CLI to display trigger ID, type, name, and URL e.g. slack trigger info --trigger-id "Ft123ABC456".slack feedback command to CLI. We would love to know about your experience (good or not so good) using the Slack CLI. Use this command to submit feedback or submit it directly here.slack-debug-20220915.log. This log file will be accessible in the .slack/logs folder on your computer. Note: The CLI will auto-cleanup log files older than one week from the .slack/logs folder.Bug fixes
slack trigger and slack workspace command will return an 'Error: unknown command' if an invalid command is executed e.g. slack trigger <invalid_command> or slack workspace <invalid_command>.slack auth and slack collaborators default to slack auth list and slack collaborators list command if no additional arguments are passed in the command.Breaking changes
Please update your app in accordance with the changes outlined below to ensure that it continues to work as expected.
FunctionHandler is no longer exported. Use the SlackFunctionHandler type when building custom functions instead. Alternatively, use the new SlackFunction helper included in this release.DefineType() no longer accepts callback_id as a property. The callback_id has been deprecated in favor of name.options.client_secret_env_key property has been removed from DefineOAuth2Provider() in favor of using the add-secret CLI command. If you are using client_secret_env_key, you can remove it and then use add-secret instead to provide the value.SendDmSendMessageSendEphemeralMessage
Both text and rich_text are still supported.block_actions/view_submission/view_closed interactivity event payload:
body.user.usernamebody.trigger_idbody.tokenbody.is_enterprise_installbody.app_unfurlbody.workflow_stepbody.trigger_infobody.trigger_id, use body.interactivity.interactivity_pointer instead.uri has been renamed to url for the string type. If you're using format: "uri" as either an OpenForm input field or top-level string parameter in a custom function, please update to format: "url".Other changes
reverse-string app template has been removed.slack run. On workspaces that don't require admin approval to install apps, slack run will start a local development server without first having to have an admin accept the Terms of Service.interactive_blocks has been added to the following Slack functions:
