Setting Up A Custom Rest Source

Q: What is a Claude Code skill and how does the Setting Up A Custom Rest Source skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Setting Up A Custom Rest Source is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

Connect an arbitrary REST API to the PostHog data warehouse as a Custom source by authoring a JSON manifest, with no per-source code. Use when the user points at an API that has no built-in PostHog connector — "import data from this REST API", "sync my internal API", "connect this API from its docs", "build a custom data warehouse source" — and gives a docs URL or a natural-language description of the endpoints. Walks through drafting the RESTAPIConfig manifest (auth — bearer, API key, HTTP basic, or OAuth2 client credentials / refresh token — pagination, record path, incremental cursor, parent/child fan-out), validating it, test-reading live rows to verify the field mappings, and creating the source. If the API already has a native PostHog connector, use setting-up-a-data-warehouse-source instead — this skill checks the connector registry first and only handles APIs with no native connector.

From the source SKILL.md

A Custom source imports any HTTP REST API into queryable warehouse tables from a JSON manifest — no per-source Python. The manifest is a RESTAPIConfig: the same shape that powers PostHog's built-in REST connectors (Intercom, Attio, Sentry, …), so the generic REST engine handles auth, pagination, JSONPath record extraction, and incremental cursors for you. Your job is to author a correct manifest and prove it against live data before creating the source.

What this skill does

Setting Up A Custom Rest Source is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/setting-up-a-custom-rest-source/ and loads when your prompt matches the skill's trigger.
