Seq.App.Teams.AdaptiveCard 1.0.0

Seq.App.Teams.AdaptiveCard

Seq alerting application for Microsoft Teams with AdaptiveCard support. Based on Seq.App.Teams application.

Notes

To connect application instance to Teams you need to provide Teams Webhook url. You can find required instructions here.

Because Teams currently doesn't support AdaptiveCard templating, it is done on application side using AdaptiveCards.Templating library.

Context

Default template source: default-template.json. Used when no template specified.

Payload Examples

Those examples could be used with AdaptiveCard designer.

Custom Functions

In addition to standard AdaptiveTemplate functions, application implements several custom functions:

• _nomd(param): this function takes single parameter of any type and in case of string escapes all supported markdown control sequences. Function is useful when rendered text could contain markdown-like character sequences as AdaptiveCard doesn't provide option to disable markdown from template.
