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.

6Replay

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 "Add to Replay" from the detail/swipe menu, or tap + in the replay list.
  2. Edit method, URL, headers, body; optionally schedule or loop.
  3. Send and inspect the response; past results are kept.

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.
