Add the Slack Webhook URL, which you can create in Slack by clicking Browse apps > Custom Integrations > Incoming Webhooks.

If the Slack Webhook URL is not specified, the Slack integration posts to the channel that is configured on the Slack side, and you can override the channel and user icon by configuring it on the Instana side.

Slack App


It is mandatory to have a valid logged in Instana session during the installation process of the Instana Slack App.


The installation process starts with clicking the Add to Slack button as follows. After you grant access to read:links and write:links, you are forwarded to a tenant selection page where you choose the tenants unfurling should apply to. For all selected tenants, a new API token with the name Slack Token is generated. This token is used to resolve desired preview information.
