Frequently asked questions

MockLane is a developer platform for webhook testing and mock API creation. It lets you capture incoming webhooks, build mock API endpoints with dynamic responses, replay captured requests, and receive test emails via sandbox inboxes.

No. The free plan is completely free with no credit card required. You can start capturing webhooks and creating mock APIs in seconds.

MockLane combines webhook capture, mock API creation, request replay, and email sandboxes in a single platform. Most tools only handle one of these. Plus, our template engine ships 121 data generators powered by Faker.

Create an endpoint in your dashboard, and you'll get a unique URL. Point your webhook provider (Stripe, GitHub, Shopify, etc.) to that URL, and MockLane captures every request with full headers, body, and metadata.

Yes. Click any captured request and hit 'Replay' to resend it to any URL. You can modify headers and body before replaying, making it easy to debug and test edge cases.

Captured requests are kept until you delete them or delete your account — there is no per-plan expiry. The exception is a capture URL created without an account, which is deleted along with everything captured at it 24 hours after it is created. You can export captures at any time.

Mock endpoints let you create fake API responses without writing backend code. Define a path, method, status code, and response body — MockLane serves it instantly. Great for unblocking frontend development.

Yes. Use template variables like {{faker.name()}}, {{faker.email()}}, {{randomInt(1,100)}}, or {{request.body.userId}} to generate realistic, dynamic responses. We ship 121 Faker-based generators, plus direct access to any Faker method.

Response sequences let a mock endpoint return different responses on successive calls. For example: first call returns 200, second returns 429, third returns 500. Perfect for testing error handling and retry logic.

Yes. Upload your OpenAPI/Swagger spec and MockLane auto-generates mock endpoints for every path. Go from spec to working mock API in seconds.

Email sandboxes give you a dedicated email address (e.g., myapp@inbox.mocklane.com) that captures all incoming emails. Use it to test email-sending features like signup confirmations, notifications, and transactional emails.

Yes. Each sandbox comes with SMTP credentials. Configure your app to use our SMTP server, and all emails land in your sandbox inbox — no real emails are sent.

Not yet. Pro and Team are coming soon. Until then every feature is free on the Free plan, within its limits, and no card is needed. Press "Notify me" on the pricing page and we'll email you when they launch.

Everyone who signs up before paid plans launch gets 50% off their first year of Pro or Team.

No. Every feature stays on the Free plan, and so do its limits. Paid plans only add higher limits and faster support.

Yes, once paid plans launch: email info@mocklane.com within 14 days of your purchase for a full refund. No questions asked. See the contact page for what to include.
