The CSBScratchpadUtil API allows consumers to share "extra" information that is outside of any other Service Bridge service, with their providers.

This information is stored as name-value pairs in the Scratchpad [sn_sb_scratchpad] table. The shared information must be associated with tasks that are of one of two types: provider tasks or remote tasks.

If the associated task is active, the updated scratchpad information syncs to the consumer instance. If a task is deactivated or deleted, the information in the scratchpad is also deleted after a specified number of days; by default three. This default is defined in the sn_sb.scratchpad.autodelete.days property.

Both providers and consumers can add, update, and remove information to and from the Scratchpad table. Producers update this information using the PSBScratchpadUtil API.

To access this API, the Service Bridge for Consumers application must be installed. This API runs in the sn_sb_con namespace.
