Example of request JSON (Cell Review Event)

{
  "appData":{
     "formCtxtId": 6,
     "objectId": 11632,
     "useUdn": true
  },
  "neoPlasticCellularityPct": "21",
  "viableCellPct": "12",
  "user": 1,
  "time": "10-29-2014 1:15",
  "comments": ""
}

Example of response JSON

"{
  \"id\":14313,
  \"time\":\"10-29-2014 1:15\",
  \"appData\":{
    \"formCtxtId\":6.0,
    \"objectId\":11632.0
  },
  \"neoPlasticCellularityPct\":\"21\",
  \"user\":1.0,
  \"viableCellPct\":\"12\",
  \"containerId\":6,
  \"comments\":\"\"
}"

NOTE:

To get the formId and formCtxId, execute the below SQL query:

select 
  c.name as formName, c.identifier as formId, ctx.identifier as formCtxId, ctx.entity_type as level, cp.title as cp 
from 
  dyextn_containers c  
  inner join catissue_form_context ctx on ctx.container_id = c.identifier 
  left join catissue_collection_protocol cp on cp.identifier = ctx.cp_id 
where   
  c.caption = '<form display name>'

In above SQL form display name refers to caption that user sees in Manage Forms or form data entry view

Here <form name> is the name of the form for which user wants to make data entry. e.g. for Specimen Collection Event the name is "SpecimenCollectionEvent".
