Obtain the API Base URL and Swagger/OpenAPI Docs URL
- Determine the base URL for the API you want to connect to (e.g.,
https://api.example.com). - (Optional) Obtain the direct URL to the Swagger/OpenAPI JSON or YAML documentation (e.g.,
https://api.example.com/swagger.json). If you don't have this, the service will attempt to auto-discover it.
- Determine the base URL for the API you want to connect to (e.g.,
Choose Your Authentication Method
- Decide if your API requires an API key or username/password for authentication.
A. If your API uses an API Key:
- Find out how your API provides API keys (consult your API provider’s documentation or portal).
- Log in to your API provider's dashboard/portal.
- Locate the section for API tokens/keys (frequently found under "API", "Developers", "Access", or "Security").
- Create or view your API key.
- Copy the API key for use in the next steps.
B. If your API uses Username and Password:
- Use your usual username and password registered with your API provider.
