# Made Card Partners API > Offer Made Card to your customers: a Made-hosted application, a customer link that stays valid until Made revokes it, launch URLs that open Made Card signed in, and read-only card data. No endpoint moves money. Read the For AI agents page first. Keep client_secret, the partner JWT, and every link_ token on the server. API keys name their mode: pk_test_ and sk_test_ for Test mode, pk_live_ and sk_live_ for Live mode. Keys issued before these prefixes keep working. A key sent to the other mode's API gets PRTN_0106, naming the API base it belongs to. ## Docs - [Overview](https://api.madecard.com/partners/docs/overview.md): What the partner API does and how the pieces fit. - [Quickstart](https://api.madecard.com/partners/docs/quickstart.md): Connect one customer end to end with curl and Made Link. - [Environments](https://api.madecard.com/partners/docs/environments.md): Base URLs for Test mode and Live mode. - [Test data](https://api.madecard.com/partners/docs/test-data.md): Test customers for Test mode: emails and phone numbers whose codes show on screen, SSNs, and decisions. - [Auth and tokens](https://api.madecard.com/partners/docs/authentication.md): API key formats (pk_test_, pk_live_), partner JWTs and the token lifetimes. - [Apply and link](https://api.madecard.com/partners/docs/apply-and-link.md): Start a link session, open Made Link, and store the customer token. - [Web SDK](https://api.madecard.com/partners/docs/web-sdk.md): Load Made Link in the browser, open the Made window, and handle every outcome. - [Launch URLs](https://api.madecard.com/partners/docs/launch.md): Open Made Card signed in, and the allowed target paths. - [Customer data](https://api.madecard.com/partners/docs/customers.md): Which customers you can see and the read-only endpoints. - [Webhooks](https://api.madecard.com/partners/docs/webhooks.md): Signed events when a link, application or card account changes, and how to verify them. - [Errors](https://api.madecard.com/partners/docs/errors.md): The response envelope and every error code. - [Testing and go-live](https://api.madecard.com/partners/docs/go-live.md): Test mode, retries, rate limits, status checks, and the go-live checklist. - [For AI agents](https://api.madecard.com/partners/docs/ai-agents.md): Rules, call sequence, and a starter server for coding agents. ## API - [OpenAPI spec](https://api.madecard.com/partners/openapi.json): every partner endpoint, request, response, and error - [Swagger UI](https://api.madecard.com/partners/swagger): the same spec in the classic Swagger layout, for browsing every endpoint - [All docs in one file](https://api.madecard.com/partners/llms-full.txt): every guide as one markdown file - [Interactive reference](https://api.madecard.com/partners/docs): the same docs and API reference, read-only in Live mode
