How to retrieve array value in Node.js and send to next calling API-CodePudding

I am new to I have a JSON response from an API , which I need to parse two values in the JSON and then pass those value to the next API. The challenge I have is , I will have N number of Array JSON response similar to the sample I am Showing below ,this is one sample json but there will be n number of json concatenated of the same structure.

Now I want to retrieve the id and messages.messageId value within customers object and pass the same as input to next API call. How could I retrieve the matching id and message id and save it in a list to send to next API

   "id":"64146c29",
   "Customers":[
      {
         "id":"4a61aaf2-c6bc-41ae-9ecd-041825135bf5",
         "startTime":"2022-11-29T16:00:07.623Z",
         "endTime":"2022-11-29T16:00:07.630Z",
         "attributes":{
            "contactId":"30000236925961000-B1"
         },
         "provider":"Beta",
         "peer":"7126e24c-affa-4fb8-a450-50a644764a32",
         "messages":[
            {
               "messageId":"ce67fba0ef44523f0d9a9d5dd5649642"
            }
         ],
         "type":"sms",
         "recipientCountry":"US",
         "recipientType":"mobile"
      },
      {
         "id":"bbed4f9c-1be7-4fe5-ba37-5e058e9f16c6",

CodePudding user response：

To get this data (id and messageId) of each customer, you will have to loop over the customers array and return those value from each customer object.

const customersDataToSendToApi = customersDataFromApi.Customers.map(customer => {
return {customer.Id, customer.messages.messageId}
})

The customersDataToSendToApi is already an array which you can pass in the body of API POST request. I hope this helps.

Yes, you do the same thing to the array of multiple json since you say they have similar structure.

arrayOfMultipleJson.map(eachJson =>{
eachJson.Customers.map(customer => {
return {customer.Id, customer.messages.messageId}
})
})

Do you get the picture I am painting? If you don't mind me asking, what scenario makes you get multiple JSON in one API call?
