With the introduction of flows, we have created the following types of blocks to help you customize your flows to meet your teams’ needs. To learn more about any of these blocks, or for assistance in adding them to your flows, contact your Hyperscience representative.
Block types and settings
Application-level and flow-level settings
While some blocks have settings that allow you to customize how they work, many blocks are affected by application-level or flow-level settings. To learn more about these settings, see Application Settings Overview and Flow Settings.
Input Blocks
Formerly known as “Input Connectors,” Input Blocks allow you to integrate your organization’s data sources into our system. Through these blocks, you can process documents from a variety of sources, such as inboxes, message queues, or folders on the network.
A full list of the Input Blocks we currently support, along with more details about each, can be found in Input Blocks.
Settings
No matter how many Input blocks you choose to enable, information about those blocks is contained in a main Input block for your flow. This block has the settings described below.
| Name | Required? | Description | | Allow API submissions | No | Indicates whether the flow accepts submissions submitted via API. | | Allow manual submissions | No | Indicates whether the flow accepts manually uploaded submissions. |
Submission Initialization
The Submission Initialization Block contains settings that connect your flow to your:
AWS S3 submission retrieval store,
OCS submission retrieval store,
Generic web storage (HTTP/HTTPS) submission retrieval store,
[v39.2 and later] Azure Blob Storage retrieval store.
Settings
You can customize the functionality of your block by editing the settings described below.
AWS S3
S3 Submission Retrieval Store
If you are using an S3 bucket as your submission retrieval store and you are not authenticating through IAM roles, provide your AWS access key ID and secret access key in the S3 Submission Retrieval Store field.

- In the dialog box that appears, click Save & Deploy.
Azure Blob Storage
The Azure Blob Storage option for submission retrieval storage is available in v39.2 and later.
If you are using Azure Blob Storage as your submission retrieval store, you can use the fields described below to configure the system’s connection to the blob.
Azure Blob Storage Authentication Type
From the Azure Blob Storage Authentication Type drop-down list, select the authentication type the system should use to access the blob:
- SAS Token Only
- Service Principal
- Managed Identity
- Account Key
When you select an authentication type, additional settings appear.
Settings for SAS Token Only authentication
| Name | Required? | Description |
| Azure Blob Storage Account URL | Yes | The URL of the storage account (e.g., https://
Settings for Service Principal authentication
| Name | Required? | Description |
| Azure Blob Storage Account URL | Yes | The URL of the storage account (e.g., https://
Settings for Managed Identity authentication
| Name | Required? | Description |
| Azure Blob Storage Account URL | Yes | The URL of the storage account (e.g., https://
Settings for Account Key authentication
| Name | Required? | Description |
| Azure Blob Storage Account URL | Yes | The URL of the storage account (e.g., https://
If incorrect authentication information is entered, the flow runs for the attempted file-ingestion attempts will fail. The flow runs’ output will contain error messages passed to the system by Azure.
Classification Blocks
We’ve divided our Classification function into two blocks: one for Machine Classification and another for Manual Classification.
Machine Classification
With machine classification, Hyperscience can automatically match your submissions to Structured, Semi-structured, or Additional layouts. Machine classification requires training to recognize the kinds of submissions you process through Hyperscience.
Settings
| Name | Required? | Description | | Image Correction | No | Identifies and corrects the orientation of Semi-structured images by rotating them. | | Faster PDF Transcription | No | If enabled, the system processes pages in PDF files in their native format. | | Captured Image Enhancement | No | Improves machine readability of Semi-structured documents captured by mobile devices. |
Manual Classification
Manual Classification, or Classification Supervision, allows your keyers to manually match submissions to their layouts. Depending on your flow, keyers may perform Classification Supervision if the system cannot match a submission to a layout with high confidence.
Settings
You can customize the functionality of your Manual Classification Block by adding Task Restrictions.
| Name | Required? | Description | | Default task restrictions | No | Select the task restrictions that should be applied to tasks created by this block. |
Identification Blocks
We’ve created two Identification blocks to cover both our machine Identification and Identification Supervision capabilities.
Machine Identification
With Machine Identification, you can automate the identification of fields and tables in your submissions.
Settings
Other than the settings under “Block Details,” Machine Identification Blocks have no block-specific settings.
Manual Identification
Manual Identification allows your keyers to complete Field ID Supervision or Table ID Supervision tasks, ensuring the system transcribes the correct content in the Transcription steps of the data-extraction process.
Settings
You can customize the functionality of your Manual Identification Block by adding Task Restrictions.
Transcription Blocks
Just as we did with Classification and Identification, we’ve divided our Transcription capabilities into Machine Transcription and Manual Transcription Blocks.
Machine Transcription
In the Machine Transcription Block of your flow, Hyperscience automatically transcribes the content of your submissions.
Settings
Other than the settings under “Block Details,” Machine Transcription Blocks have no block-specific settings.
Manual Transcription
Manual Transcription, or Transcription Supervision, lets your keyers manually enter the text found in fields or tables.
Settings
You can customize the functionality of your block by editing the settings described below.
Task Restrictions
Supervision
| Name | Required? | Description | | Supervision Transcription masking | No | Prevents users from inputting invalid characters during Supervision Transcription tasks. | | Table output manual review | No | Generates a Table Transcription task for manual review. | | Create Manual Transcription Task for Tables with Blank Cells | No | Always sends blank cells to Manual Transcription, enabled by default. |
Flexible Extraction Block
Depending on your flow’s configuration, Flexible Extraction tasks allow your keyers to validate transcriptions or add transcriptions to manually categorized Structured pages.
Settings
You can customize the functionality of your block by editing the settings described below.
Task Restrictions
Supervision
| Name | Required? | Description | | Flexible Extraction Transcription masking | No | Prevents users from inputting invalid characters during Flexible Extraction tasks. |
Collation Block
We’ve created a Collation Block to allow the grouping of files, documents, and pages into cases.

| Name | Required? | Description | | Replace case data from duplicate file names | No | Replaces case data from repeated file names within the same case. |
Custom Supervision Block
To enable the tailoring of a Supervision task’s interface, we’ve created a Custom Supervision Block.
Settings
| Name | Required? | Description | | Task purpose | Yes | The custom task name given to the Custom Supervision task in the Task Queue. | | Default task restrictions | No | Select the task restrictions that should be applied to tasks created by this block. | | Custom Supervision transcription masking | No | Prevents users from inputting invalid characters during Custom Supervision Transcription tasks. |
Database Blocks
Database Blocks allow you to make queries from Hyperscience to databases, which increases the overall speed of your flows.
Custom Code Blocks
Custom Code Blocks enable you to transform and validate extracted submission data before Hyperscience sends it to your downstream systems.
| Rule Type | Description | Examples | | Field normalization / Data transformation | Change the formatting of data for compatibility with downstream systems. | - Make sure names have the correct capitalization. - Convert driver's license information to a specific format. | | Data validation | Perform an external data lookup or check data within the submission. | - Verify that a transcribed ZIP code is valid. - Check that a customer's name matches the customer's record. | | Data augmentation | Add data to a submission's JSON to prevent processing issues. | - Determine a customer's country of residence and add the country code. |
Named Entity Recognition Block
The Named Entity Recognition Block allows you to detect key PII entities such as Names, Addresses, Locations, Organizations, and Companies.
Custom Entity Detection Block (Beta)
The Custom Entity Detection Block allows you to locate and identify single words and word patterns with regular expressions and keywords.
Routing Blocks
Routing Blocks let you send submission data to different destinations based on the criteria you specify.
API Blocks
API Blocks allow you to connect to other data sources in your organization to augment or verify extracted data.
Complete Blocks
Every flow needs a Complete Block. This block initiates Quality Assurance tasks and changes the submission’s status to “Complete.”
Output Blocks
With Output Blocks, you can send data extracted by Hyperscience to other systems for downstream processing.
