Replay HTTP Requests on iOS: Edit and Resend Captured Traffic

NetPeek can turn a captured request into a replay, let you edit its method, URL, headers, and body, then resend it. Frequently used requests can be saved as replay items for repeatable API checks.

Edit and resend a request

Save a captured request, tweak parameters and send it again — handy for API iteration and reproducing issues. One-tap create from Request Detail.

  1. Choose Replay on a captured request.
  2. Review and edit the method, URL, headers, and body.
  3. Send the request and inspect the response.
  4. Save it to the Replay list when repeat execution is useful.

What replay is for

Once you've captured a request you usually need to send it again with tweaks. Replay keeps that on the phone:

  • Reproduce a failure: fire the exact request again and find out whether it's consistent or intermittent.
  • Verify a fix: after the backend ships a change, re-send the same request and check the response.
  • Probe parameter boundaries: edit body fields, paging parameters or time ranges and watch how the server answers.
  • Change auth state: swap the token or drop the auth header to check the endpoint's permission handling.

What you can edit before sending

  • The method — switch a GET to a POST to see what the endpoint accepts.
  • The URL and query parameters: paging, filters, API version.
  • Headers: Content-Type, Authorization, your own debug headers.
  • The body, as form data, URL-encoded pairs or raw JSON.

Save one as a reusable item

  • Name a request you run often and fire it from the replay list without capturing again.
  • Schedule it or repeat it on an interval to watch an endpoint's stability over time.
  • Past results stay available, so you can compare before and after.

FAQ

Can I replay directly from a capture?

Yes. Choose Replay from the request detail or row shortcut and NetPeek pre-fills the original request.

What can I edit before replaying?

You can edit the HTTP method, URL, request headers, and body before sending.

Can a replay be reused?

Yes. Save the configuration as a replay item and run it again from the Replay list.
