Overview
SMS_OTPas a first-class auth method discriminator.400 Error400with codeSMS_OTP_CREDENTIAL_ALREADY_EXISTS.openapi/.Endpoint Shape After This Change
No endpoint path or header changes. This adds
SMS_OTPas another discriminator branch in the existing Embedded Wallet Auth credential flows.POST /auth/credentialsnow accepts an SMS OTP create request:{ "type": "SMS_OTP", "accountId": "InternalAccount:019542f5-b3e7-1d02-0000-000000000002" }The unsigned add-credential request still returns
202 AuthSignedRequestChallenge:{ "type": "SMS_OTP", "payloadToSign": "...", "requestId": "Request:7c4a8d09-ca37-4e3e-9e0d-8c2b3e9a1f21", "expiresAt": "2026-04-08T15:35:00Z" }The signed retry returns
201 AuthMethodResponse:{ "id": "AuthMethod:019542f5-b3e7-1d02-0000-000000000001", "accountId": "InternalAccount:019542f5-b3e7-1d02-0000-000000000002", "type": "SMS_OTP", "nickname": "+14155550123", "otpEncryptionTargetBundle": "{...}", "createdAt": "2026-04-08T15:30:01Z", "updatedAt": "2026-04-08T15:30:01Z" }If the target wallet already has an SMS OTP credential,
POST /auth/credentialsreturns400 Error400:{ "status": 400, "code": "SMS_OTP_CREDENTIAL_ALREADY_EXISTS", "message": "This wallet already has an SMS_OTP credential. Delete the existing one via DELETE /auth/credentials/{id} before adding a new phone number." }POST /auth/credentials/{id}/challengetreats SMS OTP like email OTP: the request body can be empty, and the response is200 AuthMethodResponsewithtype: "SMS_OTP"plus a freshotpEncryptionTargetBundle.{}POST /auth/credentials/{id}/verifynow accepts an SMS OTP verify request:{ "type": "SMS_OTP", "encryptedOtpBundle": "{\"encappedPublic\":\"...\",\"ciphertext\":\"...\"}" }The first verify leg returns
202 AuthSignedRequestChallenge; the signed retry sends the same body withGrid-Wallet-SignatureandRequest-Id, then returns200 AuthSession. SMS OTP sessions omitencryptedSessionSigningKeybecause the client keeps the TEK private key.{ "id": "Session:019542f5-b3e7-1d02-0000-000000000003", "accountId": "InternalAccount:019542f5-b3e7-1d02-0000-000000000002", "type": "SMS_OTP", "nickname": "+14155550123", "expiresAt": "2026-04-08T16:30:01Z" }Downstream
