Abstract: Systems and methods are provided for securely sharing database records in the context of a conversation at a communication platform using a secure sharing service. The secure sharing service identifies an external system user identifier for a participant in the conversation at the communication platform using an identifier associated with the participant at the communication platform, identifies permissions associated with the data record at the external system, and identifies a subset of fields of the data record viewable by the participant using the external system user identifier. The secure sharing service obtains values for the identified subset of fields of the data record from the external computing system and automatically generates a shared data record message associated with the conversation at the communication platform that includes the obtained values for the identified subset of fields of the data record.
