For asynchronous extractions, you can retrieve extraction results using either API endpoints or a webhook. A webhook allows you to receive the extraction as a push, rather than waiting for responses from API endpoints.

For this tutorial, let's try a webhook in combination with the /extract_from_url endpoint. Note you can also use the webhook with the /generate_upload_url endpoint and other asynchronous endpoints.

Prerequisites

See prerequisites.

Configure the webhook

1. Generate a destination for the webhook: navigate to https://webhook.site/ to automatically create a unique test page:

Note: Use this website solely for testing. In production, make your own destination for the webhook payload.

2. Copy the following code sample, and replace YOUR_UNIQUE_URL with your uniquely generated webhook.site URL:

curl --location --request POST 'https://api.sensible.so/v0/extract_from_url/tax_forms' \
--header 'Authorization: Bearer YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--data-raw '{"document_url":"https://github.com/sensible-hq/sensible-configuration-library/raw/main/tax_forms/1040/2021/1040_2021_sample.pdf",
"webhook": {"url":"YOUR_WEBHOOK_URL","payload":"some info you want to include in addition to the default payload, which includes extraction id, type, and parsed doc"}}'

3. In your Postman workspace, click Import, select Raw text, paste the code sample, and follow the prompts to import to code sample.

4. Click Send in Postman.

Check the webhook response

Visit your unique URL at webhook.site to verify there's a response at the URL that includes parsed_document and webhook objects that look something like the following:

{

	"webhook": {
		"payload": "some info you want to include in addition to the default payload, which includes extraction id, type, and parsed doc",
		"url": "https://webhook.site/b37c53a3-fb75-48d6-df696ebd1388"
	},
	"parsed_document": {
		"year": {
			"type": "string",
			"value": "2021"
		},
		"filing_status.single": {
			"type": "boolean",
			"value": true
		},
		"filing_status.married_filing_jointly": {
			"type": "boolean",
			"value": false
		},
		"filing_status.married_filing_separately": {
			"type": "boolean",
			"value": false
		},
		"filing_status.head_of_household": {
			"type": "boolean",
			"value": false
		},
		"filing_status.qualifying_widow": {
			"type": "boolean",
			"value": false
		},
		"name": {
			"type": "string",
			"value": "Connor Roy"
		},
		"ssn": {
			"type": "string",
			"value": "337-18-2333"
		}
	}
