API Details

  • Carrier Registrations: Specify only the carriers and features (spamRemediation, brandedCallerId) you need (minimum one carrier with at least one feature).
    • No need to specify all three carriers. Omitted features default to false (and will return with a detailedStatus of pending.initialOptOut). Note: This differs from, and is more flexible than, the in-app CSV Upload submission process which requires all carrier columns in the template (AT&T, T-Mobile, Verizon) even if the value is "No", and takes in true/false values rather than "Yes"/"No", but the outcome will be the same.
    • Use a value of true to opt in a phone number to branding or spam remediation for a given carrier feature. Response will return with a detailedStatus of pending.initialOptIn
    • Use the GET brandedPhoneNumbers to check on the status of your phone number as it goes through the review process (pending.initialOptIn --> submitted.OptIn --> approved.OptIn or rejected.OptIn)
  • POST endpoint is only used to add a phone number for the first time; PATCH endpoint allows for updating existing registrations including changing carriers or features.
