Troubleshoot Customer.io form submissions

Last updated July 20, 2026

When a submission fails, Vyro returns an error code that tells you what to fix. Use this guide to resolve the most common ones.

Successful submission

A 201 response means the submission was accepted:

{ "code": "success", "description": "Form submission received. Processing is asynchronous." }

Processing is asynchronous, so allow a short delay before the enquiry appears in your dashboard.

Common errors

401 — Unauthorised

The x-api-key header is missing or wrong.

  • Confirm the header is named exactly x-api-key.
  • Confirm the key matches the one from your Account Manager, with no extra spaces.

403 — Forbidden

The submission isn't allowed for this form or showroom.

  • Check the showroom_code matches the showroom that owns the form.
  • Confirm your showroom has been enabled for the integration — ask your Account Manager if you're unsure.

400 — Bad request

The submission was authorised but the body was rejected.

  • Invalid keys: a key in values doesn't match a field on the form. Remove it or correct the spelling. See Map Customer.io fields to your Vyro form.
  • form_not_found: the form_id doesn't exist. Confirm you're sending the correct form ID.
  • Validation errors: a required field is missing or a value is the wrong format (for example, an invalid email). Correct the value and resend.

429 — Too many requests

Too many submissions arrived from the same source in a short window. Space out retries and avoid resending duplicates.

The enquiry went to the wrong dealer

  • If you used postcode routing, confirm the customer's postcode is listed in the intended dealer's primary market area.
  • If the enquiry landed on the fallback location, the postcode didn't match any dealer. See Route enquiries to the right dealer by postcode.
  • If you sent an explicit location, remember it always overrides postcode routing.
