Verify API v4 Response Fields and Examples
Session Characteristics
These fields contain information about the session itself.
| Field Name | Description | Example Values | Applicable Product |
|---|---|---|---|
solved | When a session's risk level does not qualify it for transparent mode (no challenge) it is shown an interactive challenge. In that case, this field's value indicates if the challenge was successfully solved or not. If it was in transparent mode, the field value for a valid session is true. | true, false | Arkose Protect |
session | A unique token for the Arkose Labs session. A session is the whole experience from solution load to verification. | A unique token, e.g.3595d2c014d3c5f01.1116018803,or null | Arkose Detect Arkose Protect |
session_created | An ISO 8601 UTC timestamp signifying the time the session was created | e.g.2019-07-15T02:45:13+00:00,or null | Arkose Detect Arkose Protect |
check_answer | An ISO 8601 UTC timestamp signifying the time that the Enforcement Challenge user supplied answered were evaluated | e.g.2019-07-15T02:45:13+00:00,or null | Arkose Protect |
verified | An ISO 8601 UTC timestamp signifying the time that the request to the verify endpoint was made. | e.g. ``2019-07-15T02:45:13+00:00 | Arkose Detect Arkose Protect |
attempted | Whether the user attempted to solve the Enforcement Challenge, or not. | true, false | Arkose Protect |
security_level | A number that indicates the security level used for this session. Be aware that security_level can have a null value - usually because the session was an audio mode session. Audio mode does not use security_level. | A security level, e.g. 20 | Arkose Protect |
session_is_legit | Indicates if Arkose Labs certifies there are no telltales of non-legitimate activity in the session. | true, false | Arkose Detect Arkose Protect |
previously_verified | Indicates if a session has already been verified | true, false | Arkose Detect Arkose Protect |
session_timed_out | Indicates if a session timed out before it was solved | true, false | Arkose Detect Arkose Protect |
suppress_limited | Indicates if the session qualified for low security, but failed verification. Low security is when a session has qualified to run in transparent mode, or use a no wrong answer enforcement challenge, such as the pick your favorite color challenge. | true, false | Arkose Protect |
theme_arg_invalid | Whether the theme arg setting at verification matched the original theme arg passed in at session setup. A theme arg is a parameter passed by a customer to Arkose Labs. It requests a security tier or UX test mode. | true, false | Arkose Protect |
suppressed | Suppressed is the old name for transparent mode. This field shows if the the user was offered transparent mode. | true, false | Arkose Protect |
punishable_actioned | Punishable is an attack mitigation tactic, which randomly fails verification attempts, even if the response was correct. This field indicates if punishable was activated. | true, false | Arkose Protect |
telltale_user | UID for a combination of telltales that identify a particular bad user or organization. | A string such as 999b-fwh,or null | Arkose Detect Arkose Protect |
failed_low_sec_validation | Indicates that the intention was to offer the user a low security session, but they failed to qualify for it when the verification was attempted. | true, false | Arkose Protect |
lowsec_error | An identifier showing why a user was denied a low security session. | "user_credits", "rate_limit_local", "validation_checks", "rate_limit_global", or null | Arkose Detect Arkose Protect |
lowsec_level_denied | The low security level that was denied to the user. | A security level, e.g. 5 | Arkose Detect Arkose Protect |
ua | The User Agent string for the user that interacted with the EC. | "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.159 Safari/537.36“ | Arkose Detect Arkose Protect |
ip_rep_list | An identifier which specifies which IP reputation database this IP address has been seen at. | "tor", "sfs_tor", "sfs", or null | Arkose Detect Arkose Protect |
optional | An object containing optional return values such as client_encrypted_mode_key or get_pass values.Also, relevant data being sent to Arkose Labs via our accepted methods (see: Data Exchange (Requires Support login)) appears in this object. The specific keys and values inside this object vary based on implementation | {"blob": "lHpwagBqx3JOI7t9Ka0KUdIeHZbIjAYPPB72k Du2Zb5BwNiC6qJx5gS0f5c3EzcZ9d"}, or null | Arkose Detect Arkose Protect |
game_number_limit_reached | Game number limit is an optional setting that restricts the number of attempts a user can have at solving the EC. This field can show if the user reached the number of attempts allowed. | true, false | Arkose Protect |
user_language_shown | Shows the language code of the language in which the challenge was presented to the user. | A string such as “en“ or null | Arkose Protect |
telltale_list | The list of telltales that were identified as possible candidates during a session. | A string e.g. "999b-fwh", or null | Arkose Detect Arkose Protect |
device_id[Early Access] | Note: You must request that Arkose turn on device_id for your account. Otherwise, its value will always be nulldevice_id can identify changes a user's device if those two devices are distinguishable based on collected fingerprints.device_id isn't comprised of uniquely identifiable attributes and so can't be used for situations when, for example, a user switched from one iPhone 14 to another while keeping all the settings the same. | A string containing a hash value or null | |
challenge_type | The type of challenge that the end-user solved. | A string e.g. "audio", "transparent", "visual" or null | Arkose Detect Arkose Protect |
