# Commit a prompt version

POST https://api.respan.ai/api/prompts/{prompt_id}/commits/
Content-Type: application/json

Commits the current draft as a read-only version. No new draft is created; create a version to keep editing.

Reference: https://www.respan.ai/docs/apis/prompts/commit-prompt-version

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.
- `Authorization` header (bearer token, required) — Use a dashboard JWT only for dashboard-authenticated endpoints. Respan API-key endpoints use the respanApiKey auth field instead.
