Slack's Legal Hold APIs allow developers to build applications with read and write permissions to Slack's legal holds. These applications can ensure that relevant data is saved when an organization needs to place a legal hold in Slack.
The Legal Hold APIs can do the following:
These permissions include being able to set the custodians on each legal hold, which determines the data that Slack will preserve.
Legal holds do not provide access to the contents of what is preserved. Rather, the legal hold API lets Slack know which data needs to be preserved, while the Discovery API is required to collect data.
The menu on the left will provide you with the info you need to get started.
