Deprecated - URL field syntax

This syntax is now deprecated. Please use the new batch request syntax outlined here.

The Web API can receive batch requests with up to 1,000 URLs per batch. This is useful if you need to make many requests and would like to save time. To make a batch request, use the following syntax:

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.

curl -X POST 'https://api.webit.live/api/v1/batch/web' \
--header 'Authorization: Basic <credential string>' \
--header 'Content-Type: application/json' \
--data-raw '{ 
    "url": [
        "https://www.example1.com",
        "https://www.example2.org",
        "https://www.example3.net"
    ],
    ...
    "storage_type": "s3",
    "storage_url": "s3://Your.Repository.Path/",
    "callback_url": "https://your.callback.url/path"
}'

Request options

Batch requests use the same parameters as asynchronous requests, but can receive multiple URLs in the url field.

ParameterRequiredDescription

url

Required

The pages or resources to be fetched. Note: when using a URL with a query string, encode the URL and place it at the end of the query string.

method

Optional (default = GET)

The method for requesting a URL from the target server.

country

Optional (default = all)

Country used to access the target URL, use ISO Alpha-2 Country Codes i.e. US, DE, GB

locale

Optional (default = EN)

String || LCID standard locale used for the URL request.

headers*

Optional

JSON with key/value structure to pass the required headers.

format

Optional (default = JSON)

Enum: JSON | HTML - The data response format. HTML - in case of error, returns JSON with error message.

parse

Optional (default = false)

Enum: true | false - True - the page's content will be parsed and returned in a JSON format. False - Response will include page headers and raw data (without parsing). When using parse = true, format must be set to “JSON”.

parser

Optional (default = null)

String | Define a custom parsing template. See Parsing Templates.

render

Optional (default = false)

Enum: true | false - enables or disables Javascript rendering on the target page.

render_flow

Optional (default = null)

String | Define a series of actions to be performed on the page prior to data collection. See Page Interactions.

render_options

N/A

A collection of rendering-related settings. See Rendering options.

storage_type

Optional

ENUM: s3 | gs - Use s3 for Amazon S3 and gs for Google Cloud Platform. Leave blank to enable Push/Pull delivery.

storage_url

Optional

Repository URL: s3://Your.Bucket.Name/your/object/name/prefix/ - Output will be saved to TASK_ID.json Leave blank to enable Push/Pull delivery.

callback_url

Optional

A url to callback once the data is delivered. The WebAPI 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).

All URLs in a batch request receive the same parameters (country, locale, parse, repository, etc.)

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.

Responses

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>'

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

Once 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/7a07a96d-c402-4d98-a17f-4ecb390d11a3' \
--header 'Authorization: Basic <credential string>'

The response object lists the status of the overall batch, as well as the individual tasks and their details:
