Run Workflow | extend

Run a Workflow with files. A Workflow is a sequence of steps that process files and data in a specific order to achieve a desired outcome. A WorkflowRun will be created for each file processed. A WorkflowRun represents a single execution of a workflow against a file.

Request

This endpoint expects an object.

workflowIdstringRequired

The ID of the workflow to run.

Example: "workflow_BMdfq_yWM3sT-ZzvCnA3f"

fileslist of objectsOptional

An array of files to process through the workflow. Either the files array or rawTexts array must be provided. Supported file types can be found here. There is a limit if 50 files that can be processed at once using this endpoint. If you wish to process more at a time, consider using the Batch Run Workflow endpoint.

An array of files to process through the workflow. Either the `files` array or `rawTexts` array must be provided. Supported file types can be found [here](https://docs.extend.ai/2025-04-21/product/general/supported-file-types). There is a limit if 50 files that can be processed at once using this endpoint. If you wish to process more at a time, consider using the [Batch Run Workflow](https://docs.extend.ai/2025-04-21/developers/api-reference/workflow-endpoints/batch-run-workflow) endpoint.

rawTextslist of stringsOptional

An array of raw strings. Can be used in place of files when passing raw data. The raw data will be converted to .txt files and run through the workflow. If the data follows a specific format, it is recommended to use the files parameter instead. Either files or rawTexts must be provided.

versionstringOptional

An optional version of the workflow that files will be run through. This number can be found when viewing the workflow on the Extend platform. When a version number is not supplied, the most recent published version of the workflow will be used. If no published versions exist, the draft version will be used. To run the "draft" version of a workflow, use "draft" as the version.

Examples:

"3" - Run version 3 of the workflow
"draft" - Run the draft version of the workflow

An optional version of the workflow that files will be run through. This number can be found when viewing the workflow on the Extend platform. When a version number is not supplied, the most recent published version of the workflow will be used. If no published versions exist, the draft version will be used. To run the `"draft"` version of a workflow, use `"draft"` as the version. Examples: - `"3"` - Run version 3 of the workflow - `"draft"` - Run the draft version of the workflow

priorityintegerOptional1-100Defaults to 50

An optional value used to determine the relative order of WorkflowRuns when rate limiting is in effect. Lower values will be prioritized before higher values.

metadatamap from strings to anyOptional

An optional metadata object that can be assigned to a specific WorkflowRun to help identify it. It will be returned in the response and webhooks. You can place any arbitrary key : value pairs in this object.

To categorize workflow runs for billing and usage tracking, include extend:usage_tags with an array of string values (e.g., {"extend:usage_tags": ["production", "team-eng", "customer-123"]}). Tags must contain only alphanumeric characters, hyphens, and underscores; any special characters will be automatically removed.
