Extend

Connect to Extend AI to access structured data extraction and document processing capabilities. Supports parsing files, running workflows, and extracting structured data from various document types.

Set up in Extend

1. Sign in to the Extend dashboard at https://dashboard.extend.ai.

2. Open Developer Settings and create/copy an Extend API key.

Set up in StackAI

1. Open Settings → Connections, add a connection, and select Extend.

2. Enter the credentials and connection details in the fields below.

3. Save the connection and check its connection status. Select this saved connection when configuring an action or feature that uses it.

Connection fields

StackAI field	Required	What to enter
API Key	Yes	Your Extend AI API key from your Extend dashboard. Provider instructions.

Provider documentation: Setup reference.

Verify the connection

Check that the connection is healthy. Then run a read operation against a resource the connected account can access. A successful connection check confirms authentication; it does not guarantee permission for every action.

If access is denied, check the credential or OAuth permissions, the selected account or environment, and access to the specific resource. Update expired credentials or reconnect after permissions change.

Use an action

1. Add the required Extend action to the workflow.

2. Select a connection when the action requests one.

3. Complete the required fields. Use the reference picker when a value comes from another workflow step.

4. Run the workflow and inspect the action’s output. Check the result before using it in a later step.

Actions

Field	Type	Required	Description
Processor ID	string	Yes	Enter the Extend processor ID to run.
Raw Text	string	Yes	Provide the text content to process directly.
Synchronous Processing	boolean	No	Wait for processing to complete before returning results. Default: true.

Important behavior

Actions that create, update, send, or delete data can change the connected service. Review their inputs before running them. A retry can repeat an operation; consider this when configuring retries for actions that change data.

The catalog lists the fields and capabilities available in the supplied provider definition. Availability can also depend on your deployment and organization’s Feature Access settings.
