channel

string

Channel to send the message to. If absent, the message goes to the channel selected for the token.

color

string

Allow text to use default colors - use the default of ‘normal’ to not send a custom color bar at the start of the message.

Allowed values for color can be one of ‘normal’, ‘good’, ‘warning’, ‘danger’, any valid 3 digit or 6 digit hex color value.

Specifying value in hex is supported since Ansible 2.8.

Default: "normal"

domain

string

Slack (sub)domain for your environment without protocol. (i.e. example.slack.com) In 1.8 and beyond, this is deprecated and may be ignored. See token documentation for information.

icon_emoji

string

Emoji for the message sender. See Slack documentation for options. (if icon_emoji is set, icon_url will not be used)

icon_url

string

Url for the message sender’s icon (default https://www.ansible.com/favicon.ico)

Default: "https://www.ansible.com/favicon.ico"

integer

Automatically create links for channels and usernames in msg.

Choices:

  • 1 ← (default)

  • 0

message_id

string

added in community.general 1.2.0

Optional. Message ID to edit, instead of posting a new message.

If supplied channel_id must be in form of C0xxxxxxx. use {{ slack_response.channel_id }} to get channel_id from previous task run.

Corresponds to ts in the Slack API (https://api.slack.com/messaging/modifying).

msg

string

Message to send. Note that the module does not handle escaping characters. Plain-text angle brackets and ampersands should be converted to HTML entities (e.g. & to &) before sending. See Slack’s documentation (https://api.slack.com/docs/message-formatting) for more.

parse

string

Setting for the message parser at Slack

Choices:

  • "full"

  • "none"

thread_id

string

Optional. Timestamp of parent message to thread this message. https://api.slack.com/docs/message-threading

token

string / required

Slack integration token. This authenticates you to the slack service. Make sure to use the correct type of token, depending on what method you use.

Webhook token: Prior to 1.8, a token looked like 3Ffe373sfhRE6y42Fg3rvf4GlK. In 1.8 and above, ansible adapts to the new slack API where tokens look like G922VJP24/D921DW937/3Ffe373sfhRE6y42Fg3rvf4GlK. If tokens are in the new format then slack will ignore any value of domain. If the token is in the old format the domain is required. Ansible has no control of when slack will get rid of the old API. When slack does that the old format will stop working. ** Please keep in mind the tokens are not the API tokens but are the webhook tokens. In slack these are found in the webhook URL which are obtained under the apps and integrations. The incoming webhooks can be added in that area. In some cases this may be locked by your Slack admin and you must request access. It is there that the incoming webhooks can be added. The key is on the end of the URL given to you in that section.

WebAPI token: Slack WebAPI requires a personal, bot or work application token. These tokens start with xoxp-, xoxb- or xoxa-, eg. xoxb-1234-56789abcdefghijklmnop. WebAPI token is required if you intend to receive thread_id. See Slack’s documentation (https://api.slack.com/docs/token-types) for more information.

username

string

This is the sender of the message.

Default: "Ansible"

validate_certs

boolean

If false, SSL certificates will not be validated. This should only be used on personally controlled sites using self-signed certificates.

Choices:

  • false

  • true ← (default)
