2014: A contact card already exists for this phone number

A contact card already exists for this phone number. Use PATCH to update it instead of creating a new one.

A contact card already exists for this phone number. This is an HTTP 409 error indicating you attempted to create a duplicate contact card.

  • Use PATCH /v3/contact_card?phone_number={phone_number} to update the existing card instead of POST to create a new one.
  • A POST to a card whose setup never completed retries that setup rather than returning this error, so a 409 always means a working card is already in place.
