Submit JSON provides a backend for HTML forms and a notification API for application events. A site or application sends a payload to an endpoint, and the service stores submissions and delivers notifications through email, webhooks or supported integrations. A JavaScript client and REST interface let it work with static pages as well as frontend frameworks and server-side applications.
The public feature list includes project-level endpoint organization, custom notification templates, submission search and export, and configurable recipients. Integrations include Slack, Discord, Telegram, Zapier and Google Sheets. Anti-spam options include CAPTCHA services, honeypot fields, origin restrictions and API-key settings. Those controls need to be configured for the intended form; their presence is not a promise that every endpoint is secure by default. Submit JSON offers free signup and is intended for contact forms, feedback, surveys and operational events where a developer wants submission handling without building the entire storage and notification workflow.
