Before you begin - Integrations - The probes

[Anish Reghu]

Here's a checklist of things we need to probe while we prepare for Integrations with the ServiceNow platform:

• Is it an import from or export to ServiceNow?
• Understanding the direction – Sending /Receiving information?
• Which system is initiating the conversation?
• Is it a push or a pull?
• Is it a conversation based on a request from ServiceNow or an external system exporting data using ServiceNow API?
• Is it a one-time integration or do you need it real-time?
• Does the data need to be updated real-time or at periodic intervals?
• Is it unidirectional or bidirectional?
• If it is bidirectional – Which system will have the final say if something becomes out of sync?
• What common protocols are available at both the source and destination system?
• Do you need all the information all the time or can we do incremental updates?
• Is an incremental update possible?
• Do we have tools already available for addressing the requirement? (ServiceNow store)
• What level of error reporting or retry do we need? If the remote system is not responding and instead of 50 records, we receive only 48, what should be done? Generate report? Create incident? Or expected?
• Understanding the amount of data being exchanged and the time taken to exchange is critical. This helps keep the performance issues at bay.
• Are there data retention policies in place? Then explore capabilities like Table rotation and Archiving or remote table (cannot store data but need to access data).
• Security credentials required for the integration?
• • Is the API exposed to ServiceNow a public one or vice versa?
  • Or do you need credentials or vice versa?
  • Does the account have the proper roles and ACLs?
  • What type of credentials are required? Login/password, OAuth, JWT or API key?
