difference between REST message and scripted RESTAPI?

[suvro]

Hi Friends,

What is the difference between REST message and scripted REST API?

When should we use REST message and when should we use scripted REST API?

Please help me by giving suitable examples.

Thanks and Regards,

Hi,

Rest Message is used for sending outbound updates to an external system from Service Now. If a third party application supports REST then you can send data from Service Now using the rest message.

Create a REST message

Scripted REST API on the other hand enables inbound updates from an external system. If an external system needs to send data to Service Now and if you need to process custom changes(validations etc) which are not supported by OOB REST API's then you can write a scripted REST web service to process inbound requests from external systems.

Hello, 

I need to create a Webservice API where input is: Sys ID of any record and output is: all *related* active records to that sys id. The relationships between the tables is maintained in Relationships under system definition.

Could you please guide me how to implement this? Sample code would be great.

Input: Sys ID of the record 
Output: All *RELATED* active records from *VARIOUS* tables (in the following JSON format):
{
"result": [
{
"Sys ID": "5520267",
"CI Name": "Record 1",
"Table Name": "u_table_a"
},
{
"Sys ID": "5520367",
"CI Name": "Record 2",
"Table Name": "u_table_a"
},
{
"Sys ID": "8331210",
"CI Name": "Record 1",
"Table Name": "u_table_b"
},
{
"Sys ID": "8321210",
"CI Name": "Record 2",
"Table Name": "u_table_b"
},
{
"Sys ID": "3042006",
"CI Name": "Record 3",
"Table Name": "u_table_b"
},
{
"sys_id": "4509847",
"CI Name": "Record 1",
"Table Name": ""u_table_c"
}
{
"sys_id": "4509247",
"CI Name": "Record 2",
"Table Name": ""u_table_c"
}
]
}
