Making a prediction to extract data via the Sypht API has two basic steps:
Upload a document and specify the prediction workflow options
Retrieve the results
File upload requests return a fileId which can be used to refer to that file in subsequent requests and workflows; for example -- when retrieving the extraction results later.
Extraction workflows are asynchronous. You may upload multiple files in parallel before fetching the results. However, result fetch is synchronous by default and requests will block until pending workflows on the requested file have completed. This behaviour can be altered via requests parameters, however we recommend the default behaviour for both speed and performance.
This guide will demonstrate how to make uploads and predictions using API calls in Postman. Please see our provided clients to do this programmatically.
Request headers
Content-Type = multipart/form-data
Accept= application/json
Authorization= Bearer {{access token}}
Request Payload
Field extraction parameters
There are three ways to specify fields to be extracted in the request payload. Only one of the following must be included in the request payload:
(preferred) products: list(string) of AI product_ids which can be found under marketplace under the documentation tab of each product. e.g. ['invoices', 'ndis-claims']
fieldSets: list(string) of individual fieldsets to be extracted. e.g. ['sypht.invoice', sypht.bank']
fieldSet: (string) of a single fieldset to extract
File Upload parameter
fileToUpload: file binary of a PDF, PNG or JPG to extract fields from. Maximum file size supported is 20Mb with maximum page limit of 16.
File can also be uploaded as a base64 string in the payload under the /fileupload/json endpoint with fileToUpload being a base64 encoded string of a document PDF, JPG, PNG, etc.
Other parameters
tags: An optional string tag to identify a set of documents for convenience
workflowId <todo>
workflowOptions <todo>
locale <todo>
Response
The fileId in the response is the unique identifier used for the uploaded document which can be used to retrieve the result of the document in the following section.
After submitting a /fileupload/ request, the extraction request is queued asynchronously and results can be retrieved via a GET request to /results/<fileId> with the fileId found in the response.
For the above example, a GET request to api.sypht.com/result/final/f15ead36-dd97-4e1e-8db8-cad0fb9f5e07
In the response json, extractions are returned under results > fields for each of the fields in the AI product selected in the request (see marketplace for details of each field).
