Re: Referring existing entities in Atlas using Rest API

Hi Anshu,

You can connect to existing entity be referring the guid of already created
entity.
Below is the format of JSON.

 {

"entity": {
 ...
 ...
"Location" : {
"guid": "<%Existing entity guid)%>",
"typeName": "<type_name_of_existing_entity>"
...
...
}

}

Hi Anshu ,

Yes, array should be used.
Example:

   "Locations":[
      {  
         guid:"<GUID>",
         typeName:“<type name>"
      },
      {  
         guid:"<GUID>",
         typeName:“<type name>"
      },
      {  
         guid:"<GUID>",
         typeName:“<type name>"
      }
…...
   ]


Thanks,
Sharmadha S.

Hi,

Thanks for replying this thing works perfectly for the single referential
entity but *what format to be used for an array of already existing
entities. *
*Can we use an array of JSON for that attribute?*
