a first user interface associated with the group-based communication platform, wherein the first user is associated with an administrator account of a group of the group-based communication platform; or

a second user interface associated with a third-party resource, wherein the first request is received via an application programming interface.

8. The method of claim 1 , wherein the first message is transmitted via a communication channel or a direct messaging instance.

9. The method of claim 1 , further comprising:

determining that a current time is after an end of the first period of time; and

dissociating the indicator from the first message.

10. A system comprising:

one or more processors; and

one or more computer readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising:

receiving, from a first computing device of a first user associated with a group of a group-based communication platform, a first request to store data, associated with a characteristic, transmitted via the group-based communication platform, for a first period of time in a database associated with the group, wherein the first period of time is different than a second period of time for retaining data per a data retention rule;

receiving, from a second computing device associated with a second user, a first message transmitted via the group-based communication platform;

responsive to a determination that the first message is associated with the characteristic, storing the first message in the database for the first period of time;

receiving, from a third computing device associated with a third user of the group-based communication platform and after an expiration of the second period of time but before an expiration of the first period of time, a second request to access a conversation associated with the first message; and

withholding the first message from content presented in association with the conversation.

11. The system of claim 10 , wherein the operations further comprise:

storing, based at least in part on receiving the first request, an instruction to associate an indicator with at least one of received or incoming data, associated with the characteristic, transmitted via the group-based communication platform; and

associating the first message with the indicator based at least in part on the determination that the first message is associated with the characteristic.

12. The system of claim 11 , wherein the operations further comprise:

receiving, from the first computing device, a third request to cancel the first request;

based at least in part on receiving the third request, causing the indicator to be dissociated from previously stored data associated with the characteristic;

removing, based at least in part on causing the indicator to be dissociated from the previously stored data, the previously stored data from the database;

receiving a second message, associated with the characteristic, transmitted via the group-based communication platform; and

storing the second message in the database based at least in part on the data retention rule.

13. The system of claim 10 , wherein the operations further comprise:

receiving, from the first computing device, a third request to receive stored data associated with the characteristic; and

sending, to the first computing device based at least in part on the third request, the stored data comprising at least the first message.

14. The system of claim 10 , wherein the operations further comprise:

receiving, from the first computing device, a third request to exclude a communication channel of the group-based communication platform from a specified data retention rule associated with the characteristic;
