Use with AI assistants
AI coding assistants write better PayLater integrations when they read these docs instead of
guessing. Every page is published as plain Markdown, with an llms.txt index, so you can point
your assistant at the docs in a few lines.
What is published
These files are rebuilt from the docs on every update, so they always match this site.
| File | What it is |
|---|---|
/llms.txt | An index of every page with a one-line summary, in the llms.txt format. Start here. |
/llms-full.txt | The whole site as one Markdown file (about 110 KB), for loading everything at once. |
/<page>.md | A Markdown copy of each page, for example /generate-payment-link.md. Every page also links to its own copy under View as Markdown. |
/docs.json | The same content as structured data, including every API endpoint with its method, URLs and parameters, for your own tools. |
Claude Code and Codex
Both read a project instructions file at the start of each session: Claude Code reads
CLAUDE.md (and can read AGENTS.md instead), Codex reads AGENTS.md.
Add this section to that file in the repository that holds your PayLater integration:
## PayLater integration
PayLater is a Buy Now, Pay Later payment provider. When working on the PayLater
integration, use the official developer docs, not memory:
- Index of all pages: https://docs.paylaterapp.com/llms.txt
- Whole site in one file: https://docs.paylaterapp.com/llms-full.txt
Read the relevant page before writing or changing API calls, webhook handling or
refunds. Use the sandbox (https://connect.uat.paylaterapp.com) while developing.
Never put live client secrets or real shopper data in code, prompts or logs.The assistant fetches the pages it needs while it works. To load everything up front instead, ask it to
read https://docs.paylaterapp.com/llms-full.txt at the start of the session.
Cursor
- Type @Docs in the chat, choose Add new doc and enter
https://docs.paylaterapp.com/. Name it PayLater and refer to it as @PayLater in your prompts. - For one topic, attach that page's Markdown copy instead, for example
https://docs.paylaterapp.com/webhooks.md.
Chat assistants
In ChatGPT, Claude, Gemini and similar assistants, either:
- download
llms-full.txtand attach it to the conversation or project, or - paste the link to a single page's Markdown copy if the assistant can browse the web.
Good practice
- Keep secrets and shopper data out of AI tools. Do not paste live client secrets, webhook secrets, or shopper names, phone numbers or emails into prompts. Use the sandbox credentials from the Test environment page while developing.
- Check what the assistant writes. Assistants can still get details wrong. Compare amounts, status values and webhook verification against the relevant page, and test the full flow in the sandbox before you go live.
- Refresh after updates. The files change when the docs change. If your tool keeps its own copy, as Cursor's indexed docs do, re-index after a new release.
