## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `ONETAPCHECKIN_ADD_PARTICIPANTS` | Add Participants | Add one or more existing profiles to one or more lists without checking them in. This deliberately excludes add-all-profiles and initial attendance fields to prevent unexpectedly broad or historical mutations. |
| `ONETAPCHECKIN_CREATE_LIST` | Create List | Create an event/check-in list. The provider currently creates open registration even when disabled during creation, so this tool does not expose that unreliable flag; update the list afterward when registration must be changed. |
| `ONETAPCHECKIN_CREATE_PROFILE` | Create Profile | Create one person profile without adding it to a list. OneTapCheckIn automatically creates a global passport. This tool does not send a confirmation email. |
| `ONETAPCHECKIN_CREATE_PROFILES` | Create Profiles | Create 1 to 25 person profiles in input order using one provider request per profile. Confirmation emails are always disabled. Provider validation or conflict failures are reported per item and later profiles are still attempted, so partial creation is possible and successful creations are not rolled back. Authentication, rate-limit, server, and malformed-success failures abort the batch. |
| `ONETAPCHECKIN_DELETE_LIST` | Delete List | Permanently delete one list by ID. This is intentionally limited to one known list and never invokes the provider's bulk or delete-all operation. |
| `ONETAPCHECKIN_DELETE_PROFILE` | Delete Profile | Permanently delete one profile. This also removes the profile's automatically created global passport and never invokes the provider's bulk or delete-all operation. |
| `ONETAPCHECKIN_FIND_LISTS` | Find Lists | Get one list by exact ID or search the connected organization's lists. Search returns one page and a continuation cursor. |
| `ONETAPCHECKIN_FIND_PARTICIPANTS` | Find Participants | Get one participant by exact ID or search attendance records by list, profile, status, text, or date range. Search returns one page and a continuation cursor. |
| `ONETAPCHECKIN_FIND_PROFILES` | Find Profiles | Get one profile by ID or search profiles by identity, list, passport, or check-in code. Returns one page and a continuation cursor. |
| `ONETAPCHECKIN_GET_ORGANIZATION` | Get Organization | Return the organization associated with the connected API key. The response does not expose the organization's subscription tier. |
| `ONETAPCHECKIN_GET_PROFILE_CUSTOM_FIELDS` | Get Profile Custom Fields | Return the organization's configured profile custom-field definitions so an agent can use valid field names and value types when creating or updating profiles. |
| `ONETAPCHECKIN_LIST_ALERTS` | List Alerts | Return one page of organization alert and automation rules together with outbound check-in confirmation settings. |
| `ONETAPCHECKIN_LIST_PASSPORTS` | List Passports | List one page of standard passports for exactly one profile or participant. Use next_page to continue when a full page is returned; the provider does not support an unfiltered list-all call. |
| `ONETAPCHECKIN_REMOVE_PARTICIPANT` | Remove Participant | Remove one participant record from its list. This deletes the list membership and attendance record, not the underlying profile. |
| `ONETAPCHECKIN_UPDATE_LIST` | Update List | Partially update a list. Omitted fields are preserved even though the provider uses PUT. |
| `ONETAPCHECKIN_UPDATE_PARTICIPANT` | Update Participant | Update metadata on one participant record without performing check-in or checkout. Omitted fields are preserved. |
| `ONETAPCHECKIN_UPDATE_PARTICIPANT_ATTENDANCE` | Update Participant Attendance | Check in, check out, undo check-in, or undo checkout for one known participant. These operations change attendance history; undo actions retain attachments. This tool never sends visitor alerts. |
| `ONETAPCHECKIN_UPDATE_PARTICIPANT_ATTENDANCE_BATCH` | Update Participant Attendance Batch | Apply one shared check-in, checkout, undo check-in, or undo checkout operation to 1 to 25 participants in input order, using one provider request per item. Items execute independently: validation, not-found, and conflict failures are reported per item and do not stop later items, so partial updates are possible and successful changes are not rolled back. Authentication, rate-limit, server, unexpected client, and malformed-success failures abort the batch. Check-in never sends visitor alerts. |
| `ONETAPCHECKIN_UPDATE_PROFILE` | Update Profile | Partially update one profile. Omitted fields are preserved even though the provider uses PUT. |
