Build and validate common WeChat Official Account API requests in your browser, with URL, JSON preview, and copyable curl commands.
Used to debug the underlying credential acquisition process, usually just fill in the AppID and AppSecret.
JSON format extended parameters are supported; the tool automatically replaces {{appId}}, {{appSecret}}, {{accessToken}}, {{openId}} in the template.
This API uses GET and does not require a request body.
Please fill in: AppID、AppSecret
When developing custom menus, customer-service messages, or user-information features for a WeChat Official Account, a single incorrect endpoint, query parameter, or JSON field can cause a request to fail. This tool builds common Official Account API requests in the browser so developers can verify required fields, JSON structure, request URLs, and HTTP methods, then copy a generated curl command.
The tool only assembles and previews requests locally; it does not send them to WeChat on your behalf. AppSecret and Access Token values are sensitive credentials. Use them only on a trusted device, do not include them in screenshots or shared links, and clear the inputs after debugging.
Why does the tool generate a command instead of calling the API directly? WeChat APIs involve cross-origin restrictions, approved domains, and credential-protection requirements. A transparent request preview and curl command make it easier to inspect the parameters and execute the request from your own backend or secure terminal.
What should I do when the JSON is invalid? Make sure property names and strings use double quotes, remove trailing commas, and check that all brackets and braces are paired.
