# Get file by id

Retrieve metadata for a single file by its unique identifier. Returns the file's name, MIME type, size in bytes, processing status (`pending`, `completed`, or `failed`), author, and creation date.

Files are attachments (images, documents, audio, video) that can be embedded in docs, data entries, or other content. Use this endpoint to check a file's processing status after upload.

    "description": "The Dovetail Public API provides programmatic access to your Dovetail workspace.\n\n## Core concepts\n\n- **Projects** — Containers for organizing qualitative research. They hold data, docs, highlights, tags, and insights.\n- **Data** — Documents within a project that capture raw research data such as interview transcripts, survey responses, and session recordings. Available via `/v1/data`. The legacy `/v1/notes` endpoints access the same underlying resource.\n- **Docs** — Rich-text documents for writing up research reports, sharing findings, and publishing deliverables. Docs replace the deprecated insights resource.\n- **Highlights** — Selected passages of text or time ranges in transcripts that have been marked as significant during analysis.\n- **Tags** — Labels applied to highlights to categorize findings (e.g. 'Usability Issue', 'Feature Request').\n- **Channels** — Automated AI-powered pipelines that continuously analyze high-volume customer feedback (app reviews, NPS, support tickets) into structured topics.\n- **Contacts** — People in your contacts database such as interview participants or customers.\n- **Folders** — Hierarchical containers for organizing projects, docs, channels, and other content.\n- **Files** — Attachments (images, documents, audio, video) that can be embedded in docs, data entries, or insights.\n\n## Authentication\n\nAll requests require a Bearer token in the `Authorization` header. Generate API tokens from your Dovetail workspace settings.\n\n## Base URL\n\nAll API endpoints are served under `https://dovetail.com/api`."
