The base class for JSON serializable class objects

A supplemental object that will display after the rest of the message. Considered legacy - recommended replacement is to use message blocks instead.

https://api.slack.com/reference/messaging/attachments#fields

Args

text
The main body text of the attachment. It can be formatted as plain text, or with markdown by including it in the markdown_in parameter. The content will automatically collapse if it contains 700+ characters or 5+ linebreaks, and will display a "Show more…" link to expand the content.
fallback
A plain text summary of the attachment used in clients that don't show formatted text (eg. IRC, mobile notifications).
fields
An array of AttachmentField objects that get displayed in a table-like way. For best results, include no more than 2-3 field objects.
color
Changes the color of the border on the left side of this attachment from the default gray. Can be any hex color code (eg. #439FE0)
markdown_in
An array of field names that should be formatted by markdown syntax - allowed values: "pretext", "text", "fields"
title
Large title text near the top of the attachment.
title_link
A valid URL that turns the title text into a hyperlink.
pretext
Text that appears above the message attachment block. It can be formatted as plain text, or with markdown by including it in the markdown_in parameter.
author_name
Small text used to display the author's name.
author_subname
Small text used to display the author's sub name.
author_link
A valid URL that will hyperlink the author_name text. Will only work if author_name is present.
author_icon
A valid URL that displays a small 16px by 16px image to the left of the author_name text. Will only work if author_name is present.
image_url
A valid URL to an image file that will be displayed at the bottom of the attachment. We support GIF, JPEG, PNG, and BMP formats. Large images will be resized to a maximum width of 360px or a maximum height of 500px, while still maintaining the original aspect ratio. Cannot be used with thumb_url.
thumb_url
A valid URL to an image file that will be displayed as a thumbnail on the right side of a message attachment. We currently support the following formats: GIF, JPEG, PNG, and BMP. The thumbnail's longest dimension will be scaled down to 75px while maintaining the aspect ratio of the image. The filesize of the image must also be less than 500 KB. For best results, please use images that are already 75px by 75px.
footer
Some brief text to help contextualize and identify an attachment. Limited to 300 characters, and may be truncated further when displayed to users in environments with limited screen real estate.
footer_icon
A valid URL to an image file that will be displayed beside the footer text. Will only work if footer is present. We'll render what you provide at 16px by 16px. It's best to use an image that is similarly sized.
ts
An integer Unix timestamp that is used to related your attachment to a specific time. The attachment will display the additional timestamp value as part of the attachment's footer. Your message's timestamp will be displayed in varying ways, depending on how far in the past or future it is, relative to the present. Form factors, like mobile versus desktop may also transform its rendered appearance.

            footer_icon: A valid URL to an image file that will be displayed
                beside the footer text. Will only work if footer is present. We'll
                render what you provide at 16px by 16px. It's best to use an image that
                is similarly sized.
            ts: An integer Unix timestamp that is used to related your attachment
                to a specific time. The attachment will display the additional timestamp
                value as part of the attachment's footer. Your message's timestamp will
                be displayed in varying ways, depending on how far in the past or future
                 it is, relative to the present. Form factors, like mobile versus
                 desktop may also transform its rendered appearance.

An Attachment, but designed to contain interactive Actions Considered legacy - recommended replacement is to use message blocks instead.

https://api.slack.com/legacy/interactive-message-field-guide#attachment_fields https://api.slack.com/reference/messaging/attachments#fields

Args

actions
A collection of Action objects to include in the attachment. Cannot exceed 5 elements.
callback_id
The ID used to identify this attachment. Will be part of the payload sent back to your application.
text
The main body text of the attachment. It can be formatted as plain text, or with markdown by including it in the markdown_in parameter. The content will automatically collapse if it contains 700+ characters or 5+ linebreaks, and will display a "Show more…" link to expand the content.
fallback
A plain text summary of the attachment used in clients that don't show formatted text (eg. IRC, mobile notifications).
fields
An array of AttachmentField objects that get displayed in a table-like way. For best results, include no more than 2-3 field objects.
color
Changes the color of the border on the left side of this attachment from the default gray. Can either be one of "good" (green), "warning" (yellow), "danger" (red), or any hex color code (eg. #439FE0)
markdown_in
An array of field names that should be formatted by markdown syntax - allowed values: "pretext", "text", "fields"
title
Large title text near the top of the attachment.
title_link
A valid URL that turns the title text into a hyperlink.
pretext
Text that appears above the message attachment block. It can be formatted as plain text, or with markdown by including it in the markdown_in parameter.
author_name
Small text used to display the author's name.
author_subname
Small text used to display the author's sub name.
author_link
A valid URL that will hyperlink the author_name text. Will only work if author_name is present.
author_icon
A valid URL that displays a small 16px by 16px image to the left of the author_name text. Will only work if author_name is present.
image_url
A valid URL to an image file that will be displayed at the bottom of the attachment. We support GIF, JPEG, PNG, and BMP formats. Large images will be resized to a maximum width of 360px or a maximum height of 500px, while still maintaining the original aspect ratio. Cannot be used with thumb_url.
thumb_url
A valid URL to an image file that will be displayed as a thumbnail on the right side of a message attachment. We currently support the following formats: GIF, JPEG, PNG, and BMP. The thumbnail's longest dimension will be scaled down to 75px while maintaining the aspect ratio of the image. The filesize of the image must also be less than 500 KB. For best results, please use images that are already 75px by 75px.
footer
Some brief text to help contextualize and identify an attachment. Limited to 300 characters, and may be truncated further when displayed to users in environments with limited screen real estate.
footer_icon
A valid URL to an image file that will be displayed beside the footer text. Will only work if footer is present. We'll render what you provide at 16px by 16px. It's best to use an image that is similarly sized.
ts
