Use this when your workflow already produces unified diffs or generated patches. #### JWT claims Required scopes: `git:write` Requires per repo scope: Yes Deprecated: Use `/api/repos/{repo_name}/diff-commit` instead. ## OpenAPI ````yaml https://api.pierre.code.storage/api/openapi.json post /api/v1/repos/diff-commit openapi: 3.1.0 info: description: >- The Code Storage HTTP API exposes repository management, Git reads, and write workflows over plain HTTPS. ## Authentication Send a signed JWT in the `Authorization: Bearer ` header on every request. - Organisation-scoped endpoints such as `GET /api/repos` require organisation scopes like `org:read` - Repository-scoped endpoints require a JWT whose `repo` claim names the target repository - Write operations require the relevant scope such as `git:write` or `repo:write` ## Pagination List endpoints use cursor-based pagination. - `cursor` is an opaque token returned by the previous response - `limit` defaults to `20` and is capped per endpoint - `has_more` tells you whether another request is available - `next_cursor` becomes the next `cursor` value ## Paths Preferred routes use the shorter `/api/...` form. Legacy `/api/v1/...` aliases remain documented where they are still supported and are marked as deprecated when a preferred route exists. ## Repository names in paths - Names containing `/` (or any other character that is not safe in a URL path segment) **must** be URL encoded so the value occupies a single path segment. For example, `pierre/example` becomes `pierre%2Fexample` and the request URL is `/api/repos/pierre%2Fexample/...`. - Plain names that contain only URL-safe characters can be sent as-is: `/api/repos/dotfiles/...`. - The server URL-decodes the value before resolving the repository, so double-encoding is not required. ## Errors Most endpoints return RFC 9457-compatible problem details under `application/problem+json`, with a legacy `error` field mirrored from `detail`. Streaming commit and note workflows may return operation-specific failure bodies so callers can inspect partial results, branch state, or workflow status without parsing generic error strings. title: code.storage version: 1.0.0 servers: - description: Code Storage tenant cluster url: https://api.{cluster}.code.storage variables: cluster: default: cluster description: >- Tenant cluster identifier (e.g. pierre-dev, pierre-staging, pierre-prod). security: [] tags: - description: >- Create, inspect, update, delete, and synchronise repositories, including upstream pull-sync and generic HTTPS Git credentials for non-GitHub upstreams. name: Repositories - description: Create, delete, list, and compare branches. name: Branches - description: >- Read commit metadata and diffs, or create commits without a local Git client. name: Commits - description: >- Read repository trees, file contents, archives, and server-side search results. name: Files - description: List, create, and delete Git tags. name: Tags - description: Attach and retrieve Git notes for commits or other Git objects. name: Notes paths: /api/v1/repos/diff-commit: post: tags: - Commits summary: Diff Commit description: >- Create a commit by streaming a Git patch instead of individual file blobs.
