# Apostra developer documentation

> Start with V3 to build software that plans, runs, automates, or reports on advertising. Use Manage ads for work in the application or a connected assistant.

## Start here

- [Build software with Apostra](https://docs.apostra.com/v3/overview): Product overview, ordinary application examples, advertising agents, and compatibility.
- [Install and connect](https://docs.apostra.com/v3/quickstart): Install apostra-developer from apostra-public/apostra in Codex or Claude Code, complete OAuth, and verify access with a read.
- [Manage ads](https://docs.apostra.com/v3/manage-ads): Buying, selling, and reporting without writing software.
- [Claude and Cowork](https://docs.apostra.com/v3/client-setup#claude-and-cowork): Use the hosted MCP connector. Regular Claude and Cowork do not use the developer plugin.
- [Public marketplace](https://github.com/apostra-public/apostra): Current packages and installation instructions.

## Build your workflow

- [Choose your operating loop](https://docs.apostra.com/v3/choose-your-loop): Decide which interface, decisions, scheduling, and recovery your software owns.
- [Build an agent](https://docs.apostra.com/v3/build-an-agent): Start with a read-only prototype and add buying steps with approval.
- [Bring data in](https://docs.apostra.com/v3/bring-data-in): Events, creative assets, inventory, and seller materials.
- [Reporting pipeline](https://docs.apostra.com/v3/reporting-pipeline): Read and export delivery into your own application.
- [Authentication](https://docs.apostra.com/v3/authentication): Interactive OAuth and credentials for deployed software.

## Use an SDK from a coding agent

- [TypeScript and Python SDK guide](https://docs.apostra.com/v2/sdk): Generated client surfaces, account targeting, errors, pagination, and handoffs.
- [V3 HTTP API](https://docs.apostra.com/v3/http-api): The public operation contract and OpenAPI source behind both SDKs.
- [Authentication](https://docs.apostra.com/v3/authentication): Choose credentials and keep them in server-side configuration.
- [Generated documentation corpus](https://docs.apostra.com/llms-full.txt): The full current documentation and generated API references.

After installing either SDK, read its packaged `SKILL.md` for the
language-specific job-to-method map. The public documentation above remains the
source of truth for inputs, results, permissions, and operation behaviour.

## Current contracts and complete reference

- [V3 tool reference](https://docs.apostra.com/v2/setup/v3/tool-reference): Use with the live tools/list schemas for the authenticated account.
- [V3 limitations](https://docs.apostra.com/v2/setup/v3/limitations): Current capability and account boundaries.
- [Supported V2 REST references](https://docs.apostra.com/v2/build-with-apostra): Existing integrations and direct HTTP operations remain supported.
- [Generated documentation corpus](https://docs.apostra.com/llms-full.txt): Full documentation, including shared guides and generated API references.
