Custom Reactions

Organizations can define custom image-based reactions. In the API, custom reactions use the format custom:name for the emoji field. When listing reactions, custom entries include additional fields:

isCustom — always true
name — the custom reaction name
imageUrl — URL to the reaction image, or null if unavailable
