Quickstart

This guide walks you through a complete Atlas verification workflow from first request to final results. By the end, you will have authenticated, created a flow, submitted documents for processing, and retrieved structured OCR data.

Sandbox Base URL

https://docstream.dev.kreditmind.com

All API endpoints in this guide are relative to this base URL.

Get your credentials

Contact the Atlas account team to receive your Client-Id and Client-Secret. Store these securely—you will exchange them for a JWT token in the next step.You will also receive your provisioned product_type (for example, IDP_DEMO)

Generate an access token

Exchange your credentials for a JWT access token. The token expires after 3600 seconds (one hour).POST /v1/docstream/authtoken

curl --request POST \
  --url https://docstream.dev.kreditmind.com/v1/docstream/authtoken \
  --header "Client-Id: your-client-id" \
  --header "Client-Secret: your-client-secret"

{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "expires_in": 3600
}

Save the access_token. You will pass it as the Token header in every subsequent request.

Upload documents

Submit one or more document URLs for processing. Each document needs a file_url (a pre-signed URL pointing to the file in storage) and a document_id (your own reference for tracking).POST /v1/docstream/multiupload

Field	Type	Required	Description
`product_type`	string	Yes	The assigned product type for your company
`file_urls`	array	Yes	List of file objects to process
`file_urls[].file_url`	string	Yes	Pre-signed URL to the document file
`file_urls[].document_id`	string	Yes	Your identifier for this document

curl --request POST \
  --url https://docstream.dev.kreditmind.com/v1/docstream/multiupload \
  --header "Token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..." \
  --header "Content-Type: application/json" \
  --data '{
    "product_type": "IDP_DEMO",
    "file_urls": [
      {
        "file_url": "https://your-bucket.s3.ap-south-1.amazonaws.com/uploads/invoice.jpg",

      },

        "document_id": "3"
      }
    ]
  }'

[
  {
    "batch_id": "BATCH-30732-SIYKJ-20251121113228",
    "document_id": "1",
    "file_uuid": "03f03421-c933-46fc-a30c-ffb3ea8afd1d"

    "document_id": "2",
    "file_uuid": "03f03422-c933-46fc-a30c-ffb3ea8afd1d"
  },
  {
    "batch_id": "BATCH-30732-SIYKJ-20251121113228",
    "document_id": "3",
    "file_uuid": "03f03423-c933-46fc-a30c-ffb3ea8afd1d"
  }
]

Atlas begins processing immediately after upload. To get the data you can poll the extract endpoint in the next step.

Retrieve results

Poll this endpoint to monitor the state of your flow. You can use this alongside or instead of the callback.GET /v1/docstream/extracts?batch_id={batch_id}&page=1&per_page=50

curl --request GET \
  --url "https://docstream.dev.kreditmind.com/v1/docstream/extracts?batch_id=BATCH-42326-YSBHNW-2026043786734639&page=1&per_page=50" \
  --header "Token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

What to build next

Now that you have end-to-end results, you can:

Set up your callback_url to receive results asynchronously and eliminate polling.
Set up your crosschecks to compare results and eliminate the need for human verification.
Map error_code values like INVALID_DOC and UNRECOGNISED into your exception handling workflow.
Apply similarity_score thresholds on cross_checks to automate accept/reject decisions.
Explore the full list of supported document types and their extracted fields in the Supported Documents reference.
