sql_queries:canned-queries-json-api,sql_queries,canned-queries-json-api,JSON API for writable canned queries,"Writable canned queries can also be accessed using a JSON API. You can POST data to them using JSON, and you can request that their response is returned to you as JSON. 
                 To submit JSON to a writable canned query, encode key/value parameters as a JSON document: 
                 POST /mydatabase/add_message

{""message"": ""Message goes here""} 
                 You can also continue to submit data using regular form encoding, like so: 
                 POST /mydatabase/add_message

message=Message+goes+here 
                 There are three options for specifying that you would like the response to your request to return JSON data, as opposed to an HTTP redirect to another page. 
                 
                     
                         Set an  Accept: application/json  header on your request 
                     
                     
                         Include  ?_json=1  in the URL that you POST to 
                     
                     
                         Include  ""_json"": 1  in your JSON body, or  &_json=1  in your form encoded body 
                     
                 
                 The JSON response will look like this: 
                 {
    ""ok"": true,
    ""message"": ""Query executed, 1 row affected"",
    ""redirect"": ""/data/add_name""
} 
                 The  ""message""  and  ""redirect""  values here will take into account  on_success_message ,  on_success_message_sql ,   on_success_redirect ,  on_error_message  and  on_error_redirect , if they have been set.","[""Running SQL queries"", ""Canned queries""]",[]
