How to post nested JSON to HTTParty in Ruby on Rails - ruby-on-rails

Question

I am trying to work out the correct way to post a nested JSON object to an API using HTTParty.
I am getting a successful response using Postman to test the call:
POST: http://service.net/api
Headers: x-api-key : apikey123
Body :
{
"VehicleRequests": [{
"Id": "Vehicle1",
"Parameters": {
"Term": 60,
"CashDeposit": 10,
"DepositType": "Percentage",
"AnnualMileage": 10000
},
"PhysicalVehicle": {
"ExternalVehicleId": "12345",
"Type": "Car",
"Status": "PreOwned",
"OnTheRoadPrice": "30000",
"Mileage": "12345",
"Registration": {
"RegistrationNumber": "REGN0",
"DateRegisteredWithDvla": "01/01/2018"
}
}
}]
}
This returns:
{
"Vehicles": [
{
"Id": "Vehicle1",
"HasError": false,
"Error": null,
"FinanceQuotations": [
{
"HasError": false,
"Error": null,
"Finance": {
"Key": "HP",
"Notifications": [],
"Quote": {
.....
}
}
}
}
]
}
But i'm struggling to replicate the call from my rails app. I have a class set up which i'm calling on create
class Monthlyprice
def initialize()
#response = HTTParty.post('http://service.net/api',
:body =>{
:VehicleRequests=> [{
:Id => "Vehicle1",
:Parameters => {
:Term => 60,
:CashDeposit => 10,
:DepositType => "Percentage",
:AnnualMileage => 10000
},
:PhysicalVehicle => {
:ExternalVehicleId => "12345",
:Type => "Car",
:Status => "PreOwned",
:OnTheRoadPrice => "30000",
:Mileage => "12345",
:Registration => {
:RegistrationNumber => "REGN0",
:DateRegisteredWithDvla => "01/01/2018"
}
}
}].to_json
},
:headers => {"x-api-key" => "apikey123"})
puts(#response)
end
end
But this is returning the following error message from the API:
{"Error"=>{"UserMessage"=>"Request is invalid.", "TechnicalMessage"=>"Request Validation failed. Request had 2 error(s). 1: request.VehicleRequests[0].Id - The Id field is required.\r\n2: request.VehicleRequests[0].Parameters - The Parameters field is required.", "Code"=>"80000"}}
This is the same error that I get from the api in postman if I remove the Id and Parameters objects which suggests the contents of my VehicleRequests object is formatted incorrectly? Any advice would be great!

Can you please change the syntax like below :-
:body => {
}.to_json
that means you have to use .to_json where the body parenthesis close I think it's only syntax error.
Syntax :-
response = HTTParty.post("your request URL",
headers: {
.....
#your header content
.....
},
body: {
......
#your body content
.....
}.to_json
)
I have just edited in your code please try below code :-
#response = HTTParty.post('http://service.net/api',
:headers => {"x-api-key" => "apikey123"},
:body =>{
:VehicleRequests=> [{
:Id => "Vehicle1",
:Parameters => {
:Term => 60,
:CashDeposit => 10,
:DepositType => "Percentage",
:AnnualMileage => 10000
},
:PhysicalVehicle => {
:ExternalVehicleId => "12345",
:Type => "Car",
:Status => "PreOwned",
:OnTheRoadPrice => "30000",
:Mileage => "12345",
:Registration => {
:RegistrationNumber => "REGN0",
:DateRegisteredWithDvla => "01/01/2018"
}
}
}]
}.to_json
)
Hope this will help you :)
