Code templates in three formats
Generate fetch for browsers, curl for terminals, and Python for backends, with your authentication method and HTTP method applied.
Free, no sign-up, entirely in your browser
Design your API integration,
Design your API integration,
all the way to a working code template.
Simply choose the API, authentication method, trigger, and process. Generate an implementation flowchart, fetch, curl, and Python code, scheduling examples, Postman instructions, and a troubleshooting checklist in one place.
Free and no sign-up required. Your input stays on your device and is never sent externally.
Automation Builder
Design your API automation flow on the spot
Enter the details for your actual integration. Do not enter secrets such as API keys; the generated design uses environment variable names instead.

Built for Delivery
Know what to do after generating the code
Connect authentication, testing, and operational setup—the common sticking points in API integration—in a single design document.
Visualize the implementation flow
Organize each step in order: trigger, authentication, API call, response validation, storage, and error handling.
Standardize testing and troubleshooting
Export Postman setup instructions together with checks for errors such as 401, 403, 429, and 5xx responses.
Three Steps
Create an API automation design in three steps
Choose the integration details
Enter the API, endpoint, authentication method, HTTP method, and trigger. You do not need to enter any secret keys.
Review the code and instructions
Review the generated fetch, curl, and Python code, Postman testing instructions, and troubleshooting checklist.
Save it and start implementing
Save it in your browser or export it as Markdown or JSON. Use it for team sharing, future updates, and other projects.
FAQ
Frequently asked questions about the API code template generator
Is the API information I enter sent externally?
No. Generation, storage, and file exports all take place in your browser. For security, do not enter actual API keys or access tokens; manage them using environment variables instead.
Can I use the generated code in production as-is?
You can use it as a starting template. Before deploying to production, review the target API's official documentation, required parameters, terms of service, rate limits, error formats, and permission scopes, then verify the implementation in a test environment.
Does it support authentication methods other than Bearer Token?
It supports API Key Header, Basic Authentication, OAuth 2.0, and no authentication. For OAuth 2.0, it generates the API call made after obtaining an access token. Authorization code exchange and token refresh requirements depend on the service and must be checked separately.
Which environments are supported by the scheduling examples?
The tool generates examples for standard cron, GitHub Actions, and local environments. Adjust the time zone, execution permissions, and secret registration method to suit your environment.
Where are saved designs stored?
They are stored in your browser's localStorage. They are not automatically synced to other devices or browsers, so use the JSON or Markdown export to transfer or share them.
Do not start your next API integration from a blank page.
