Developer Tools

All tools run in the browser only (no data sent to any server). Use them to build API requests, convert text, and validate WhatsApp formats.

API Request Builder

Enter URL, method, headers and body to get cURL, JavaScript, Python and PHP ready to copy.

Select method then click «Generate code».

Base64 encode / decode

Convert text or image URL to Base64 (for attachments) or decode Base64. Processed locally in the browser.

WhatsApp JID validator

Enter a phone number or full JID. The tool validates the format and outputs the API-ready JID (e.g. 966501234567@s.whatsapp.net).

Quick code generator

Pick a common endpoint and language to get copy-ready code with placeholders for API key and session.

Select endpoint and language then click «Generate code».

Format / validate JSON (webhook)

Paste webhook payload or any JSON to format and validate it.
