Authentication

Phone Location Verification v1 supports either Basic Authentication or Bearer HMAC Authentication.

Basic Authentication

Send the provisioned merchant username and password in Authorization and include the provisioned Merchant-Key header.

Bearer HMAC Authentication

Send the provisioned Bearer token in Authorization and include Timestamp and Signature. The signature is the Base64 representation of #client_id:#hmac_base64; calculate the HMAC-SHA256 input from timestamp:client_id:POST:body_md5_base64.

Never expose credentials or signing secrets in client-side applications.
