ServiceNow Integration Frequent Question

1. What is difference between post and put and patch?
   • POST is used to create a new entity. “Post” means “after”; if you have a collection of entities and you tack a new one onto its end, you have posted to the collection. You can’t post an existing entity, and it’s common (though not always required) to use the collection’s URI to post.
   • PATCH is used to update an existing entity with new information. You can’t patch an entity that doesn’t exist. You would use this when you have a simple update to perform, e.g. changing a user’s name.
