A social networking system is configured to generate node graphs to handle specific types of customer incident reports. The node graphs comprise data structures that include nodes connected in acyclic graphs. Each node includes a node handler and optionally a user interface widget. Activating a node graph causes a subset of the nodes in the node graph to execute their node handlers. The executing node handlers generate a customer incident resolution that may include information gathering, manual review, and communications to users and third-party systems. Generation of the customer incident resolution through the node graphs allows the social networking system to handle customer incidents consistently, efficiently, and in a scalable manner.
