REST API Monitoring Tool
With Postman-like Builder
Build, test, and monitor API endpoints visually. No more guessing headers or hand-crafting JSON. GoPinger gives you a full request builder with auth helpers — then watches your REST API endpoints 24/7.
Start Monitoring APIs FreeVisual Key-Value Editors
No more raw JSON textareas. Add headers, query parameters, and form fields using an intuitive key-value editor with toggle switches, inline validation, and autocomplete for common headers.
- Toggle individual headers on/off without deleting them
- Query params sync bidirectionally with the URL field
- Bulk import from cURL or raw HTTP
Built-in Auth Helpers
Configure authentication without manually crafting headers. Select your auth type, enter credentials, and GoPinger handles the rest — generating the correct headers automatically for every check.
- Bearer Token — auto-generates Authorization header
- Basic Auth — username/password with Base64 encoding
- API Key — header or query parameter placement
Multiple Body Types
Send any payload format your API expects. Switch between JSON, XML, form-urlencoded, and raw body types with syntax validation and automatic Content-Type headers.
- JSON — validated textarea with syntax error detection
- Form URL-encoded — visual key-value editor
- XML & Raw — freeform text editors
- Auto Content-Type — set automatically based on body type
Every HTTP Method. Every Use Case.
Monitor any REST API endpoint with the right HTTP method for your use case.

We Run It — and Alert You the Moment It Breaks
Building the request is only half of it. GoPinger fires your API check as often as every 30 seconds on Pro from multiple global locations. If the status code changes, the response isn’t what you expect, or the endpoint goes down, you get an alert in under 60 seconds — by email, Slack, Teams, or webhook.
