Hi @Deepika Jain ,

In ServiceNow Event management, connectors are used to connect the Event management to external systems and services. Connector methods are the different ways that connectors can communicate with external systems. These methods include REST, SOAP, JDBC, and SNMP.

Integration types are the different ways that Event management can integrate with other systems. There are different types of integrations like Inbound, Outbound, and Bi-directional.

• Inbound integration: allows external systems to send events to ServiceNow Event management.
• Outbound integration: allows ServiceNow Event management to send events to external systems.
• Bi-directional integration: allows both ServiceNow Event management and external systems to send and receive events.

Data sources are the external systems and services that Event management can connect to. Examples of data sources include monitoring tools, IT service management tools, and log management tools.

To give you an example in layman language, imagine you want to connect your home security system with your mobile phone. Connectors are the wires/cables that connects the two systems together, the connector methods are the different ways that the wires can be connected to the systems, integration types are the different ways the systems can communicate and Data sources is the source of the data that needs to be communicated in this case it's your home security system.
