ChatGPT Actions

Integrate PayLinks with ChatGPT using OpenAI's Actions (formerly Plugins).

Overview​

ChatGPT Actions allow custom GPTs to interact with the PayLinks API. This integration lets ChatGPT users manage payment links and view analytics through natural conversation.

Setup​

1. Create a Custom GPT​

  1. Go to chat.openai.com and click "Explore GPTs" > "Create"
  2. In the Configure tab, scroll to Actions
  3. Click Create new action

2. Import the OpenAPI Spec​

PayLinks provides a public OpenAPI spec for ChatGPT Actions:

https://paylinks.ro/openapi-public.yaml

Paste this URL in the Import from URL field.

3. Configure Authentication​

  1. Set Authentication type to "API Key"
  2. Set Auth Type to "Bearer"
  3. Enter your PayLinks JWT token as the API key

4. Test the Action​

Try asking your custom GPT:

  • "List my payment links"
  • "Create a payment link for a workshop at 199 RON"
  • "Show my revenue summary"

Available Endpoints​

The public OpenAPI spec exposes a subset of the PayLinks API suitable for ChatGPT:

  • Payment link CRUD operations
  • Transaction listing
  • Analytics summary
  • Customer listing

Admin and sensitive endpoints are excluded for security.

Limitations​

  • ChatGPT Actions have a 100,000 character response limit
  • Complex multi-step operations may require multiple turns
  • File uploads are not supported through Actions
  • Token refresh requires manual intervention when expired
