Delivery methods

The Maps API supports three delivery methods:

• Real-time - the collected data is returned immediately to the user.

• Cloud Storage - the collected data is delivered to your preferred cloud storage repository.

• Push/Pull - the collected data is stored on Nimble's servers, and can be downloaded via a provided URL.

So far, all of our examples have used real-time data delivery to directly return the requested data to the user. To use Cloud or Push/Pull delivery, use an asynchronous request instead. Asynchronous requests also have the added benefit of running in the background, so you can continue working without waiting for the job to complete.

To send an asynchronous request, use the /async/serp endpoint instead. This is true regardless of which search_engine you have used. For example:

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.

Request Options

Asynchronous requests share the same parameters as real-time requests, but also include storage and callback parameters.

Parameter	Required	Type	Description
search_engine	Required	Enum: google_maps_search | google_maps_place | google_maps_reviews	The search engine from which to collect results.
query	Required Applicable only when search_engine = google_maps_search	String	The term or phrase to search for.
coordinates	Optional Applicable only when search_engine = google_maps_search	String or Object "@{latitude},{longitude},{zoom}z"	The coordinates to target. When using a string, zoom is optional (default = 14).
		"coordinates": { "latitude": "40.7590562", "longitude": "-74.0042502", "zoom": "14" }
place_id/data_id	Required Applicable only when search_engine = google_maps_place or google_maps_reviews	String	A string used by Google to identify a particular place. place_id and data_id cannot both be used in a single request.
domain	Optional	String	Search through a custom top-level domain of Google. eg: "co.uk"
country	Optional (default = all)	String	Country used to access the target URL, use ISO Alpha-2 Country Codes i.e. US, DE, GB
locale	Optional (default = en)	String	String | LCID standard locale used for the URL request. Alternatively, user can use auto for automatic locale based on country targeting.
location	Optional	String	Search Google through a custom geolocation, regardless of country or proxy location. eg: "London,Ohio,United States".
parse	Optional (default = true)	Enum: true | false	Instructs Nimble whether to structure the results into a JSON format or return the raw HTML.
storage_type	Optional Leave blank to enable Push/Pull delivery.	ENUM: s3 | gs	Use s3 for Amazon S3 and gs for Google Cloud Platform
storage_url	Optional Leave blank to enable Push/Pull delivery.	String	Repository URL: s3://Your.Bucket.Name/your/object/name/prefix/ | Output will be saved to TASK_ID.json
callback_url	Optional	String	A url to callback once the data is delivered. Nimble APIs will send a POST request to the callback_url with the task details once the task is complete (this “notification” will not include the requested data).

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:

1. Sign in to the AWS Management Console and open the AWS Key Management Service (KMS) console.

   
2. In the navigation pane, choose "Customer managed keys".

   
3. Select the KMS key you want to modify.

   
4. Choose the "Key policy" tab, then "Switch to policy view".

   
5. Click "Edit".

   
6. 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": "*"
		},
	]
}

1. 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.

Selecting a delivery method

To enable cloud delivery:

• Set the storage_type parameter to either s3 or gs

• Set the storage_url parameter to the bucket/folder URL of your cloud storage where you'd like the data to be saved.

To enable Push/Pull delivery:

• Leave both the storage_type and storage_url fields blank. Nimble will automatically recognize that Push/Pull delivery has been selected.

Response

Initial Response

When an asynchronous request is initiated, an initial response with a state of “pending” is served to the user, along with a TaskID that can be used to check the task’s progress. The TaskID is also included in the result file name, for easier tracking of the result file in the destination repository.

200 OK

{
    "status": "success",
    "task": {
        "id": "Task_ID",
        "state": "pending",
        "output_url": "s3://Your.Repository.Path/Task_ID.json",
        "callback_url": "https://your.callback.url/path",
        "status_url": "https://api.webit.live/api/v1/tasks/Task_ID",
        "created_at": "2022-07-12T11:31:06.149Z",
        "modified_at": "2022-07-12T11:31:07.765Z",
        "input": {
            ...
        }
    }
}

Checking Task Status

Asynchronous tasks can be in one of four potential states:

Status	Description
success	Task was complete and stored in the destination repository.
failed	Nimble was unable to complete the task, no file was created in the repository. A failed state will also be returned in case of unidentified or expired TaskID.
pending	The task is still being processed.
uploading	The results are being uploaded to the destination repository.

To check the status of an asynchronous task, use the following endpoint:

GET https://api.webit.live/api/v1/tasks/<task_id>

For example:

cURL

curl -X GET 'https://api.webit.live/api/v1/tasks/Task_ID' \
--header 'Authorization: Basic <credential string>'

Python

import requests

url = f"https://api.webit.live/api/v1/tasks/Task_ID"
headers = {
    'Authorization': 'Basic <credential string>'
}

response = requests.get(url, headers=headers)

print(response.status_code)
print(response.json())

Node.js

const axios = require('axios');

const url = `https://api.webit.live/api/v1/tasks/Task_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);
  });

Go

package main

import (
	"fmt"
	"net/http"
)

func main() {
	url := "https://api.webit.live/api/v1/tasks/Task_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 has the same structure as the Task Completion object that is sent to the callback_url upon task completion.

Task Completion

A POST request will be sent to the callback_url once the task is complete. If you opted for Push/Pull delivery, the output_urlfield will contain the address from which your data can be downloaded.

{
    "status": "success",
    "task": {
        "id": "Task_ID",
        "state": "success",
        "output_url": "s3://Your.Repository.Path/Task_ID.json",
        "callback_url": "https://your.callback.url/path",
        "status_url": "https://api.webit.live/api/v1/tasks/Task_ID",
        "created_at": "2022-07-12T11:31:06.149Z",
        "modified_at": "2022-07-12T11:31:07.765Z",
                "input": {
                            ...
        }
    }
}

Handling Cloud Delivery Failure

If an error was encountered in saving the result data to your cloud storage for any reason, the data will be available to download from Nimble’s servers for 24 hours. If this is the case, the task state will report “success”, but will include two additional fields – download_url and error. The download_urlfield will contain the address from which your data can be downloaded.

{
    "status": "success",
    "task": {
        "id": "Task_ID",
        "state": "success",
        "output_url": "s3://Your.Repository.Path/Task_ID.json",
        "callback_url": "https://your.callback.url/path",
        "status_url": "https://api.webit.live/api/v1/tasks/Task_ID",
        "created_at": "2022-07-12T11:31:06.149Z",
        "modified_at": "2022-07-12T11:31:07.765Z",
        "input": {
                            ...
        },
        "download_url": "https://api.webit.live/api/v1/tasks/d176cfe9-8894-48bb-a058-eeba473a638a/results",
        "error": "callback: request to https://your.callback.url/path failed, reason: getaddrinfo ENOTFOUND your.callback.url, upload: The specified bucket does not exist"
    }
}

500 Error

{
          "status": "error",
        "task_id": "<task_id>",
        "msg": "can't download the query response - please try again"
}

400 Input Error

{
        "status": "failed",
        "msg": error
}
