# Workflow step reference

Choose a source step to obtain records, processing steps to transform them, and destination steps to deliver results. Each reference lists its settings, nested fields, inputs, outputs, example data, and recovery characteristics.

The available library depends on the capabilities active in your organisation. Internal implementation steps are not presented as user-selectable steps.

## Source steps

- [App configuration](/docs/steps/app-config) — Load the invoking App's parameters and connector policy as one record.
- [Read via connector](/docs/steps/connector-read) — Stream records from a registered connector or a stored Connection.
- [Extract file content (digest)](/docs/steps/digest-extract) — Parse stored files (PDF, DOCX, …) into text segments through the document extraction.
- [Read file list](/docs/steps/object-list) — List the object keys under a prefix (or the given keys) as file references.
- [Read workflow input](/docs/steps/read-input) — Emit the records the run was invoked with, unchanged.
- [Resolve submitted review sources](/docs/steps/resolve-review-sources) — Resolve submitted review sources
- [Run subworkflow](/docs/steps/subworkflow-run) — Run another workflow of the tenant in-process and continue with its outputs.

- [Limit](/docs/steps/limit) — Keep the first N records after an optional offset, overall or per group.
- [LLM](/docs/steps/llm-complete) — Render a prompt per record and store the model's completion on it.
- [Map fields](/docs/steps/map) — Reshape each record: select, rename, drop and set fields, with ${…} templates.
- [Merge](/docs/steps/merge) — Combine the records on two named input ports: union, left/inner join or coalesce.
