script taking long time to run due to multiple api calls

I am running 3 API requests and they are making my JS script very slow.

The goal is to fetch data from the API and push it my database.

First 2 API is called using date and next_page_token. So until there is a next page token i keep calling these 2 APIs. I call them recursively.

I store the id that i get from above in an array and pass it to the next 2 APIs.

The last API call run in a loop. I loop through the ids and call the API each time.

Code:

export async function getFirstAPI(access_token, start, end, globalObject){
       let url = 'baseAPI/meetings/from=start/to=end/next_page_token=globalObject.next_page_token';
        var obj = {
            method: 'GET',
            headers: {
            authorization: 'Bearer {yourtokenhere}'
            }
         }

     let response = await fetch(url, obj)
     let data = await response.json()

     return data
}

export async function getSecondAPI(access_token, start, end, globalObject){
       let url = 'baseAPI/chats/from=start/to=end/next_page_token=globalObject.next_page_token';
        var obj = {
            method: 'GET',
            headers: {
            authorization: 'Bearer {yourtokenhere}'
            }
         }

     let response = await fetch(url, obj)
     let data = await response.json()

     return data
}

export async function getThirdAPI(access_token, id_array, globalObject){

 for(let i=0; i<id_array.length; i++){
       let url = 'baseAPI/participants/{id}';
        var obj = {
            method: 'GET',
            headers: {
            authorization: 'Bearer {yourtokenhere}'
            }
         }

     let response = await fetch(url, obj)
     let data = await response.json()
     globalObject.store_data.push(data)
   }

 return globalObject
 
}

When i run the above for a single day. That alone takes 14min 20sec. If i run it for a wider date range i am guessing this will go on for hours!!

Is there a way i can optimize this code? Or is it supposed to take this much time to run?

Any suggestions would be great!!

>Solution :

Switch from await in your loop to Promise.all or Promise.allSettled. It will work much faster. Await is not a silver bullet. It helps but in your case you are waiting for a response on each iteration instead of.. something like "fire all and collect results"

export async function getThirdAPI(access_token, id_array, globalObject) {
  const apiPromises = id_array.map(async (id) => {
    let url = `baseAPI/participants/${id}`;
    var obj = {
      method: 'GET',
      headers: { /* */ },
      authorization: `Bearer ${access_token}`
    }
    const response = await fetch(url, obj);
    return await response.json();
  });
  const results = await Promise.all(apiPromises);
  // in case globalObject.store_data is an array
  globalObject.store_data.push(...results);
  return globalObject;
}
