Vue wait 3 seconds before making request [duplicate]

Question

Because of my backend I need to wait 3 seconds before I'll make a fetchSyncedProductsResultRequest request. I was trying to use setInterval function but it won't work:

imports.js

const importSpreadsheetRequest = (self, payload, onSuccessCb, onErrorCb) => {
  const jwtToken = self.$store.state.idToken;

  return axios
    .post(`/api/v1/imports/products_batches/spreadsheet_load`, payload, {
      headers: {
        Authorization: `Bearer ${jwtToken}`,
        'Content-Type': 'application/json',
        'Accept': 'application/json'
      }
    })
    .then((response) => onSuccessCb(response.data))
    .catch((error) => onErrorCb(error))
};

sync_products.rb

  watch: {
    loadId(newValue, oldValue) {
      if (!oldValue && newValue) {
        setTimeout(3000)
        fetchSyncedProductsResultRequest(this, newValue).then(response => {
          this.fetchedProductSyncResult = response.data
        });
      }
    }
  },

How to wait 3 seconds before making this call ?

[EDIT]

here is my updated code:

  watch: {
    loadId(newValue, oldValue) {
      if (!oldValue && newValue) {
        setTimeout(
          fetchSyncedProductsResultRequest(this, newValue).then(response => {
            this.fetchedProductSyncResult = response.data['results']
          }), 3000)
      }
    }
  },
