WhosOff Integrations — Frequently Asked Questions

Question 1

What platforms can WhosOff integrate with?

Accepted Answer

WhosOff integrates with a wide range of platforms across four categories. For real-time automation via Webhooks, WhosOff connects to Microsoft Teams, Slack, Google Chat, Zapier, Make (formerly Integromat), AirOps, and any custom endpoint that accepts an HTTP POST request. For calendar synchronisation, WhosOff supports Google Calendar, Microsoft Outlook, Apple Calendar, Fantastical, and any iCal-compatible application. For Single Sign-On, WhosOff supports Microsoft Azure Active Directory, Google Workspace (SAML), Okta, OneLogin, Auth0, and Google Social Sign-On. WhosOff also exports data to Microsoft Excel and CSV, and provides a REST API for fully custom integrations.

Question 2

Does WhosOff integrate with Microsoft Teams?

Accepted Answer

Yes. WhosOff integrates with Microsoft Teams via real-time Webhooks. When a leave or overtime event occurs in WhosOff — such as a request being submitted or approved — a structured notification is delivered to a Teams channel of your choice within seconds. Common use cases include posting formatted Adaptive Cards to a dedicated leave-requests channel on every submission, sending direct messages to the relevant line manager instantly, syncing approved leave to Outlook calendars via Power Automate, and automatically escalating unanswered requests after 48 hours. Both native Teams Incoming Webhooks (zero-code) and Power Automate flows are supported.

Question 3

Does WhosOff integrate with Slack?

Accepted Answer

Yes. WhosOff integrates with Slack via Incoming Webhooks, which require no code to configure. Paste a Slack Webhook URL into WhosOff and richly formatted Block Kit messages will appear in any channel or direct message the moment a leave or overtime event fires. Typical use cases include posting all leave and overtime events to a centralised #hr-requests feed, routing overtime approvals directly to a #payroll channel, and enabling managers to respond to and approve requests without leaving Slack. Slack Workflow Builder is also supported for interactive, multi-step approval flows.

Question 4

Does WhosOff integrate with Google Chat?

Accepted Answer

Yes. WhosOff connects to Google Chat Spaces via native Space Webhooks — no code required for basic setup. Structured Card messages are delivered to your chosen HR Space when leave or overtime events occur. For Google Workspace organisations, the integration extends further: Google Apps Script or Cloud Functions can receive the Webhook to log every event to Google Sheets, auto-create Google Calendar entries when leave is approved, and keep threaded manager conversations within a single auditable Chat thread.

Question 5

Can I use Zapier or Make with WhosOff?

Accepted Answer

Yes. Zapier and Make (formerly Integromat) are fully supported as Webhook destinations for WhosOff. Pointing your WhosOff Webhook at a Zapier Catch Hook or Make HTTP trigger allows a single WhosOff event to cascade into actions across multiple connected platforms simultaneously — all without writing any code. Use cases include fanning one leave submission event out to both a Slack message and an HRIS record update at the same time, filtering so only approved overtime events notify your payroll team, logging every WhosOff event to Airtable or Google Sheets for audit reporting, and sending branded confirmation emails to employees via SendGrid.

Question 6

What is AirOps and how does WhosOff integrate with it?

Accepted Answer

AirOps is a platform for building AI-powered workflows. WhosOff connects to AirOps via Webhooks, enabling AI-driven steps to run against leave and overtime event payloads. This makes it possible to auto-generate plain-English team coverage impact summaries for managers to review before approving a request, draft personalised decline messages in your organisation's brand voice, surface weekly overtime anomalies by department for HR review, and power an internal HR assistant with live WhosOff event data as its source.

Question 7

Can I send WhosOff Webhooks to a custom or internal system?

Accepted Answer

Yes. WhosOff Webhooks work with any platform that accepts an inbound HTTP POST request — including HRIS platforms, payroll systems, internal HR portals, serverless functions such as AWS Lambda, Vercel, or Cloudflare Workers, and bespoke internal tooling. Every payload is optionally signed with HMAC-SHA256 so your receiving endpoint can verify the request originated from WhosOff before processing it.

Question 8

How quickly does WhosOff deliver Webhook payloads?

Accepted Answer

WhosOff delivers Webhook payloads in under 2 seconds of the triggering event occurring. Webhooks fire in real time with no batch delay or scheduled flush. If your endpoint is temporarily unavailable and returns a non-2xx HTTP response, WhosOff will automatically retry delivery up to 3 times using exponential backoff to ensure events are not lost during brief outages.

Question 9

How many Webhook trigger events does WhosOff support?

Accepted Answer

WhosOff currently supports six Webhook trigger events: leave request submitted, leave request approved or declined, leave request cancelled, overtime request submitted, overtime request cancelled, and overtime request approved or declined. These cover the full leave and overtime request lifecycle. Individual Webhooks can be scoped to fire on one or multiple events, and different events can be routed to different endpoints — for example, sending all leave submissions to Microsoft Teams while routing overtime approvals only to a Slack payroll channel.

Question 10

Are WhosOff Webhooks secure?

Accepted Answer

Yes. All WhosOff Webhook payloads are optionally signed using 256-bit HMAC-SHA256 cryptographic signing with a secret key that you configure. Your receiving endpoint can verify the signature on each incoming payload to confirm it genuinely originated from WhosOff and has not been tampered with in transit. This prevents third parties from spoofing fake events into your connected automation workflows.

Question 11

Does WhosOff sync leave with Google Calendar?

Accepted Answer

Yes. WhosOff generates a live iCal feed that Google Calendar can subscribe to. Once subscribed, all approved leave appears automatically in Google Calendar — for an individual employee, a team, or your entire organisation — with no manual data entry required. The feed stays live, so any updates in WhosOff are reflected in Google Calendar automatically. For more advanced use, WhosOff Webhooks can also trigger Google Apps Script to create calendar entries the moment leave is approved.

Question 12

Does WhosOff sync leave with Microsoft Outlook Calendar?

Accepted Answer

Yes. WhosOff provides a live iCal feed that Microsoft Outlook can subscribe to, bringing approved leave into Outlook alongside meetings and other calendar events. For Microsoft 365 organisations, Power Automate can extend this further by automatically creating Outlook calendar blocks the moment a leave request is approved via a WhosOff Webhook, removing the need for any manual calendar management by managers or HR.

Question 13

Which other calendar applications does WhosOff support?

Accepted Answer

WhosOff supports any calendar application that accepts an iCal feed subscription, including Apple Calendar, Fantastical, and Calendly. A single WhosOff iCal URL subscription keeps leave data current across every calendar tool in your organisation with no additional configuration required per application.

Question 14

Does WhosOff support Single Sign-On?

Accepted Answer

Yes. WhosOff supports Single Sign-On through five identity providers: Microsoft Azure Active Directory (SAML-based, for Microsoft 365 environments), Google Workspace (via a custom SAML app), Okta, OneLogin, and Auth0. A lighter-touch Google Social Sign-On option is also available, allowing team members to log in to WhosOff using a personal Google account without a full SAML configuration. SSO gives IT teams centralised access control, removes orphaned credentials when staff leave, and removes the friction of a separate WhosOff password for end users.

Question 15

Does WhosOff support SSO with Microsoft Azure Active Directory?

Accepted Answer

Yes. WhosOff integrates with Microsoft Azure Active Directory for enterprise-grade SAML-based Single Sign-On across Microsoft 365 environments. This allows IT teams to manage WhosOff access centrally through Azure AD — controlling who can log in, enforcing multi-factor authentication policies, and automatically revoking access when employees leave the organisation. A step-by-step integration guide is available in the WhosOff knowledgebase.

Question 16

Does WhosOff support SSO with Google Workspace?

Accepted Answer

Yes. WhosOff supports Single Sign-On with Google Workspace by creating a custom SAML application within the Google Workspace Admin console. Once configured, your team can sign in to WhosOff using their existing Google Workspace credentials. For organisations that prefer a simpler setup, Google Social Sign-On is also available, allowing individual Google accounts to be linked to WhosOff without a full SAML configuration.

Question 17

Can I export WhosOff data to Microsoft Excel or CSV?

Accepted Answer

Yes. Almost every screen within WhosOff — including leave reports, overtime summaries, and employee records — can be exported to XLSX or CSV format. These files can be opened directly in Microsoft Excel or imported into Google Sheets, Power BI, Looker Studio, or any other data analysis and reporting tool.

Question 18

Does WhosOff have a REST API for custom integrations?

Accepted Answer

Yes. WhosOff provides a dedicated REST API that enables organisations to build fully custom integrations. Using the API, you can pull employee data, leave balances, and request history directly into your own internal systems, dashboards, HRIS platforms, or payroll tools. The WhosOff API is particularly suited to organisations with bespoke internal systems that are not covered by the named platform integrations. Full documentation is available at whosoff.com/features/api.

Question 19

Is WhosOff free to try?

Accepted Answer

Yes. WhosOff is free to try with no credit card required. All integration features — including Webhooks, calendar sync, Single Sign-On, and REST API access — are available to explore during the free trial. You can sign up at whosoff.com/sign-up or book a personalised 20-minute demo with the WhosOff team to see the platform and its integrations in action.

Question 20

What should I do if the integration I need is not listed?

Accepted Answer

If your HRIS, payroll platform, or communication tool is not listed on the WhosOff integrations page, there are two routes to explore. First, many platforms work out of the box today via WhosOff Webhooks — any tool that can receive an HTTP POST request can be connected without dedicated integration work. Second, the WhosOff REST API enables fully custom connections to any system. If neither approach covers your requirement, the WhosOff team can be contacted directly at whosoff.com/contact-us to discuss your specific use case.
