Batch processing
If you would like to access a large number of searches, places, or reviews, batch processing can significantly speed up the process. Instead of sending individual requests, a batch request allows for up to 1,000 queries in a single request.
In the following examples, we'll demonstrate real-world use cases, and show how to use batch requests most efficiently to achieve the intended goal.
Example one - searching for multiple queries at one location
In the first example, we'll search for three different types of places located around the same coordinates.
Nimble APIs requires that a base64 encoded credential string be sent with every request to authenticate your account. For detailed examples, see Web API Authentication.

Parameters that are placed outside the requests
object, such as coordinates
, search_engine
, storage_type
, storage_url
, and callback_url
, are automatically applied as defaults to all defined requests.
If a parameter is set both inside and outside the requests
object, the value inside the request overrides the one outside.
Example two - searching for one query at multiple locations
In the next example, we'll search for one type of place at multiple coordinates:

By placing the query
parameter outside of the requests
object, we apply it as a default on all the defined requests. Thus, this bulk request would trigger four individual searches for "Restaurants" located around four unique coordinates.
Example three - combining queries and locations
Next, we combine the previously highlighted features in order to search for a different type of place at unique coordinates for each request:

Notice that for the last request, we search for "Bars" without explicitly defining the coordinates where this search should be performed. In this case, the default coordinates defined outside the requests
object would be used instead.
Request options
Batch requests use the same parameters as asynchronous requests, with the exception of the requests
object.
Setting GCS/AWS access permissions
GCS Repository Configuration
In order to use Google Cloud Storage as your destination repository, please add Nimble’s system user as a principal to the relevant bucket. To do so, navigate to the “bucket details” page in your GCP console, and click on “Permission” in the submenu.
Next, past our system user [email protected] into the “New Principals” box, select Storage Object Creator as the role, and click save.
That’s all! At this point, Nimble will be able to upload files to your chosen GCS bucket.
S3 repository configuration
In order to use S3 as your destination repository, please give Nimble’s service user permission to upload files to the relevant S3 bucket. Paste the following JSON into the “Bucket Policy” (found under “Permissions”) in the AWS console.
Follow these steps:
1. Go to the “Permissions” tab on the bucket’s dashboard:
2. Scroll down to “Bucket policy” and press edit:
3. Paste the following bucket policy configuration into your bucket:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Statement1",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::744254827463:user/webit-uploader"
},
"Action": [
"s3:PutObject",
"s3:PutObjectACL"
],
"Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*"
},
{
"Sid": "Statement2",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::744254827463:user/webit-uploader"
},
"Action": "s3:GetBucketLocation",
"Resource": "arn:aws:s3:::YOUR_BUCKET_NAME"
}
]
}
Important: Remember to replace “YOUR_BUCKET_NAME” with your actual bucket name.
Here is what the bucket policy should look like:
4. Scroll down and press “Save changes”
S3 Encrypted Buckets
If your S3 bucket is encrypted using an AWS Key Management Service (KMS) key, additional permissions to those outlined above are also needed. Specifically, Nimble's service user will need to be given permission to encrypt and decrypt objects using a KMS key. To do this, follow the steps below:
Sign in to the AWS Management Console and open the AWS Key Management Service (KMS) console.
In the navigation pane, choose "Customer managed keys".
Select the KMS key you want to modify.
Choose the "Key policy" tab, then "Switch to policy view".
Click "Edit".
Add the following statement to the existing policy JSON, ensuring it's inside the Statement array:
{
"Version": "2012-10-17",
"Id": "example-key-policy",
"Statement": [
// ... your pre-existing statements ...
{
"Sid": "Allow Nimble APIs account",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::744254827463:user/webit-uploader"
},
"Action": [
"kms:Encrypt",
"kms:Decrypt",
"kms:ReEncrypt*",
"kms:GenerateDataKey*",
"kms:DescribeKey"
],
"Resource": "*"
},
]
}
Click "Save changes" to update the key policy.
That's it! You've now given Nimble APIs permission to encrypt and decrypt objects, enabling access to encrypted buckets.
Please add Nimble's system/service user to your GCS or S3 bucket to ensure that data can be delivered successfully.
Response
Initial Response
Batch requests operate asynchronously, and treat each request as a separate task. The result of each task is stored in a file, and a notification is sent to the provided callback any time an individual task is completed.

Checking batch progress and status
POST https://api.webit.live/api/v1/batches/<batch_id>/progress
Like asynchronous tasks, the status of a batch is available for 24 hours.
curl -X GET 'https://api.webit.live/api/v1/batches/<batch_id>/progress' \
--header 'Authorization: Basic <credential string>'
import requests
url = 'https://api.webit.live/api/v1/batches/<batch_id>/progress'
headers = {
'Authorization': 'Basic <credential string>'
}
response = requests.get(url, headers=headers)
print(response.status_code)
print(response.json())
const axios = require('axios');
const url = 'https://api.webit.live/api/v1/batches/<batch_id>/progress';
const headers = {
'Authorization': 'Basic <credential string>'
};
axios.get(url, { headers })
.then(response => {
console.log(response.status);
console.log(response.data);
})
.catch(error => {
console.error(error);
});
package main
import (
"fmt"
"net/http"
)
func main() {
url := "https://api.webit.live/api/v1/batches/<batch_id>/progress"
headers := map[string]string{
"Authorization": "Basic <credential string>",
}
req, err := http.NewRequest("GET", url, nil)
if err != nil {
fmt.Println(err)
return
}
for key, value := range headers {
req.Header.Set(key, value)
}
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer resp.Body.Close()
fmt.Println(resp.StatusCode)
// Read the response body if needed
// body, err := ioutil.ReadAll(resp.Body)
// fmt.Println(string(body))
}
Response
The progress of a batch is reported in percentages.
{
"status": "success",
"completed": false,
"progress": 0.333333
}
Once a batch is finished, its progress will be reported as “1”.
{
"status": "success",
"completed": true,
"progress": 1
}
Retrieving Batch Summary
One a batch has finished, it’s possible to return a summary of the completed tasks, by using the following endpoint:
GET https://api.webit.live/api/v1/batches/<batch_id>
For example:
curl -X GET 'https://api.webit.live/api/v1/batches/<batch_id>' \
--header 'Authorization: Basic <credential string>'
import requests
url = 'https://api.webit.live/api/v1/batches/<batch_id>'
headers = {
'Authorization': 'Basic <credential string>'
}
response = requests.get(url, headers=headers)
print(response.status_code)
print(response.json())
const axios = require('axios');
const url = 'https://api.webit.live/api/v1/batches/<batch_id>';
const headers = {
'Authorization': 'Basic <credential string>'
};
axios.get(url, { headers })
.then(response => {
console.log(response.status);
console.log(response.data);
})
.catch(error => {
console.error(error);
});
package main
import (
"fmt"
"net/http"
)
func main() {
url := "https://api.webit.live/api/v1/batches/<batch_id>"
headers := map[string]string{
"Authorization": "Basic <credential string>",
}
req, err := http.NewRequest("GET", url, nil)
if err != nil {
fmt.Println(err)
return
}
for key, value := range headers {
req.Header.Set(key, value)
}
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer resp.Body.Close()
fmt.Println(resp.StatusCode)
// Read the response body if needed
// body, err := ioutil.ReadAll(resp.Body)
// fmt.Println(string(body))
}
The response object lists the status of the overall batch, as well as the individual tasks and their details:
