# How to Integrate Retool with Webex Events - Tool: Retool - Difficulty: Intermediate - Time required: 20 minutes - Last updated: April 2026 ## TL;DR Connect Retool to Webex Events by creating a REST API Resource with Webex's API base URL (https://webexapis.com/v1) and a Bot token or OAuth 2.0 Integration credentials. Build queries to list events, track registrations, manage attendee lists, and view engagement metrics — creating an event management panel that combines Webex event data with CRM records for a unified attendee operations view. ## Why Connect Retool to Webex Events? Webex Events provides a capable platform for large-scale virtual events, but post-event operations — exporting attendee lists, identifying no-shows vs. attendees, triggering follow-up sequences in your CRM, and building attendance reports for event sponsors — typically require multiple manual steps across Webex, your CRM, and email tools. A Retool Webex Events integration centralizes these operations into a single internal panel that your events team can use without accessing multiple systems. For event managers running recurring webinars or virtual conferences, a Retool dashboard brings operational clarity: seeing all upcoming events in one table, monitoring registration counts against capacity targets, and viewing real-time attendee join rates during live events. After each event, the panel enables one-click export of attendance data, automated comparison of registrants vs. actual attendees, and routing of attendee engagement scores to your CRM — workflows that would otherwise require manual data entry or custom scripting. The Webex API uses the same authentication system across all Webex products (messaging, meetings, events, calling), which means a single Retool resource configuration can support both Webex communication monitoring and Webex Events management dashboards. This unification is a key advantage of the Cisco Webex platform — your Retool integration investment extends across the full Webex product portfolio rather than requiring separate credentials and resource configurations for each Webex surface. ## Before you start - A Webex account with Event Host or Admin permissions (Webex Events requires a Webex plan that includes large meeting or webinar hosting capabilities) - A Webex Bot token (created at https://developer.webex.com/my-apps, type 'Bot') — for server-side event data access without user login - OR a Webex Integration with OAuth 2.0 and the 'spark:events_read' and 'meeting:participants_read' scopes for user-context event data - At least one completed or upcoming Webex Event or Webinar in your account for testing queries - A Retool account (Cloud or self-hosted) with permission to add Resources ## Step-by-step guide ### 1. Set up Webex API access for Events data Webex Events data is accessed through Cisco's unified Webex API — the same API used for Webex messaging and meetings. Navigate to the Webex developer portal at https://developer.webex.com/my-apps. For a Bot token (recommended for internal dashboards): Click Create a New App, select 'Bot'. Fill in Bot Name (e.g., 'Retool Events Dashboard'), choose a username (e.g., events-dashboard@webex.bot), and add a description. Click Add Bot. On the confirmation page, copy the Access Token immediately — it will only be shown once and does not expire unless regenerated. For OAuth 2.0 Integration (required for user-context event data like private registrant details): Click Create a New App, select 'Integration'. Set the Redirect URI to https://oauth.retool.com/oauth/oauthcallback (for Retool Cloud). In the Scopes section, select the scopes needed for events: - spark:events_read — read event data - meeting:participants_read — read participant/attendee data - meeting:schedules_read — read meeting schedules Copy the Client ID and Client Secret shown on the app page. For testing Webex API responses before building queries, use the Webex developer portal's interactive Try It section at https://developer.webex.com/docs/api/v1/events — enter your token and run live API calls to understand the response structure before writing Retool transformers. Note: Webex Events (for large webinars with registration) and Webex Meetings (standard meetings) are distinct API entities. Events use /events endpoints; Meetings use /meetings. Verify which type your use case requires and check that your Webex plan includes Webex Events hosting (not just standard meeting hosting). **Expected result:** You have either a Webex Bot Access Token or OAuth 2.0 Integration credentials (Client ID + Client Secret) ready to configure in Retool. ### 2. Create a REST API Resource in Retool for Webex Events Navigate to Settings (gear icon) in Retool → Configuration Variables. Add a new variable: - Name: WEBEX_TOKEN - Value: your Webex Bot Access Token (or leave for OAuth configuration) - Secret: checked Click Save. Go to the Resources tab. Click Add Resource. Type 'REST' in the search and select REST API. Configure: - Name: 'Webex Events API' - Base URL: https://webexapis.com/v1 For Bot token authentication: In the Authentication section, select 'Bearer Token'. In the Token field, enter {{ retoolContext.configVars.WEBEX_TOKEN }}. For OAuth 2.0 Integration: In the Authentication section, select 'OAuth 2.0'. Fill in: - Client ID: your Integration's Client ID - Client Secret: your Integration's Client Secret - Authorization URL: https://webexapis.com/v1/authorize - Token URL: https://webexapis.com/v1/access_token - Scopes: spark:events_read meeting:participants_read meeting:schedules_read Click Connect to authenticate via the OAuth popup window. In the Headers section for both methods, add: - Content-Type: application/json - Accept: application/json Click Save Changes. Verify connectivity: create a test query with Method GET and Path /events (or /meetings for standard meetings). A successful response confirms the resource is configured correctly. **Expected result:** The Webex Events API Resource appears in Retool's Resources list. A test query returns a 200 response confirming authentication is configured correctly. ### 3. Build a query to list Webex events and registrations Open or create a Retool app. In the Code panel, click + to add a new query. Select your Webex Events API resource. Configure the events listing query: For Webex Webinars (large events with registration): - Method: GET - Path: /meetings - Query Parameters: - meetingType: webinar - state: {{ stateFilter.value || 'inProgress,scheduled,ended' }} - from: {{ dateRange.start || new Date(Date.now() - 30 * 24 * 60 * 60 * 1000).toISOString() }} - to: {{ dateRange.end || new Date().toISOString() }} - max: {{ pagination.pageSize || 50 }} For Webex Events (if your account uses the /events endpoint): - Method: GET - Path: /events - Query Parameters: add resource, type, actorId, and from/to for filtering Add a JavaScript transformer to normalize the response from the 'items' array into a flat format suitable for Retool's Table. Set the query to run automatically and name it 'eventsQuery'. Drag a Table component onto the canvas. Set Data to {{ eventsQuery.data }}. Configure columns: title, state, startTime, endTime, durationMinutes, hostDisplayName, inviteeCount, and registrationCount. Add a date range picker component (from/to) above the table that filters the query's date parameters. Add a state filter Select with options for scheduled, inProgress, and ended. ``` // Transformer to normalize Webex meetings/events response const items = data.items || []; return items.map(event => { const startTime = event.start ? new Date(event.start) : null; const endTime = event.end ? new Date(event.end) : null; const durationMs = startTime && endTime ? endTime - startTime : 0; const durationMinutes = Math.round(durationMs / 60000); return { id: event.id, title: event.title || event.subject || 'Untitled Event', state: event.state || event.status || 'unknown', meetingType: event.meetingType || 'meeting', startTime: startTime ? startTime.toLocaleString() : 'N/A', endTime: endTime ? endTime.toLocaleString() : 'N/A', startTimeRaw: event.start || null, durationMinutes: durationMinutes || 'N/A', hostDisplayName: event.hostDisplayName || event.hostEmail || 'N/A', hostEmail: event.hostEmail || '', inviteeCount: event.inviteeCapacity || event.maxAttendees || 0, registrationUrl: event.links?.registration || event.webLink || '', isPublic: event.publicMeeting || false, registrationRequired: event.requireRegistration || false }; }); ``` **Expected result:** A Table displays upcoming and recent Webex events with title, state, start time, duration, and host information. Date range filters update the query and refresh the table. ### 4. Fetch registrants and attendees for a selected event To build the core attendee management functionality, create queries that fetch registrant and attendee data for whichever event is selected in the events table. Create a registrants query: - Method: GET - Path: /meetings/{{ eventsTable.selectedRow.id }}/registrants (for webinars with registration) - Query Parameters: max: 100 - Run mode: Automatic when inputs change; Only run when inputs have valid values Create a separate attendees query for who actually joined: - Method: GET - Path: /meetings/{{ eventsTable.selectedRow.id }}/attendees - Query Parameters: max: 100 Add transformers to both queries to normalize the 'items' arrays. The registrants response includes registration details (when they registered, custom form fields they filled in). The attendees response includes join time, leave time, and duration in session. Build a tabbed detail view below the events table with two tabs: 'Registrants' and 'Attendees'. In the Registrants tab, show a Table with displayName, email, registrationTime, and status. In the Attendees tab, show displayName, email, joinTime, leaveTime, and durationMinutes. Add a summary KPI row between the events table and the detail tabs: Stat components showing registrant_count, attendee_count, and attendance_rate (attendees / registrants * 100). Calculate these from the query data using JavaScript in a separate query or direct component expressions. For joining with CRM data, create a third query using your internal database resource that looks up contacts by email: SELECT * FROM contacts WHERE email IN ({{ JSON.stringify((attendeesQuery.data || []).map(a => a.email)) }}). Use a JOIN in a JavaScript transformer to merge CRM fields (contact ID, deal stage, account name) with the Webex attendee record. ``` // Transformer for Webex attendees response const items = data.items || []; return items.map(attendee => { const joinTime = attendee.joinedTime ? new Date(attendee.joinedTime) : null; const leaveTime = attendee.leftTime ? new Date(attendee.leftTime) : null; const durationMs = joinTime && leaveTime ? leaveTime - joinTime : 0; return { id: attendee.id, displayName: attendee.displayName || 'Guest', email: attendee.email || 'N/A', joinTime: joinTime ? joinTime.toLocaleTimeString() : 'N/A', leaveTime: leaveTime ? leaveTime.toLocaleTimeString() : 'N/A', durationMinutes: Math.round(durationMs / 60000) || 0, isHost: attendee.host || false, isPanelist: attendee.panelist || attendee.coHost || false, device: attendee.clientUserAgent ? attendee.clientUserAgent.split(' ')[0] : 'Unknown' }; }); ``` **Expected result:** Selecting an event row loads the registrant and attendee tables. KPI stats show registration count, attendee count, and attendance rate. The no-shows list identifies registrants who did not join the event. ### 5. Build post-event follow-up workflow and export functionality After events end, marketing teams need to trigger follow-up sequences and export attendance data. Build two capabilities: an immediate CSV export button and an automated post-event Workflow. For CSV export: Retool's Table component has a built-in export feature. Right-click the attendees Table header and enable 'Allow users to download as CSV'. Alternatively, create a custom 'Export CSV' button that opens a JavaScript query generating a CSV string from the attendee data, then triggers a file download using Retool's built-in download action. For automated post-event processing, create a Retool Workflow: 1. Navigate to Workflows in the Retool sidebar. Click New Workflow. 2. Add a Webhook trigger. Note the webhook URL displayed — you will call this URL from a Webex Webhook (created in the Webex developer portal) that fires when a meeting ends. 3. In the Workflow, add a Resource Query block using the Webex Events API resource to fetch the completed meeting's attendees list (the meeting ID arrives via startTrigger.data.meetingId from the webhook payload). 4. Add a Code block that filters attendees by duration (e.g., those who stayed for at least 50% of the event) for a high-engagement segment. 5. Add a Resource Query block using your CRM API resource to create or update contact records for each attendee with an 'Attended Webex Event' tag and the event title. 6. Add a final Slack notification block to post the attendance summary to your events team channel. Publish the Workflow with Publish Release. Then configure a Webex Webhook (via POST /webhooks with resource=meetings, event=ended, targetUrl=your Retool Workflow webhook URL) to trigger this Workflow automatically whenever an event ends. For complex CRM sync and multi-system post-event workflows, RapidDev's team can help architect your Retool solution. ``` // Code block: segment attendees by engagement level const attendees = block1.data.items || []; const eventDurationMinutes = startTrigger.data.durationMinutes || 60; const highEngagement = []; const lowEngagement = []; const noShow = []; attendees.forEach(a => { const durationMs = (new Date(a.leftTime) - new Date(a.joinedTime)) || 0; const durationMinutes = durationMs / 60000; const engagementPct = eventDurationMinutes > 0 ? (durationMinutes / eventDurationMinutes) * 100 : 0; const record = { email: a.email, displayName: a.displayName, durationMinutes: Math.round(durationMinutes), engagementPercent: Math.round(engagementPct) }; if (engagementPct >= 50) highEngagement.push(record); else lowEngagement.push(record); }); return { highEngagement, lowEngagement, totalAttendees: attendees.length }; ``` **Expected result:** The Workflow is published with an active webhook trigger. When a Webex event ends, Webex automatically calls the Retool webhook URL, which fetches attendees, segments them by engagement, updates the CRM, and posts a summary to Slack — completing the post-event process without manual intervention. ## Best practices - Use a Webex Bot token rather than personal access tokens for Retool event dashboards — Bot tokens are permanent and suitable for server-side use, while personal tokens expire every 12 hours requiring frequent manual refresh. - Store your Webex token in a Retool configuration variable marked as secret (Settings → Configuration Variables) and reference it via {{ retoolContext.configVars.WEBEX_TOKEN }} in the resource Bearer Token field rather than pasting it directly. - Always test attendee queries against a completed event (state=ended) during dashboard development — in-progress events may return partial data or different field structures than completed event reports. - Add a 15-30 minute processing delay after event end before querying attendee data — build this expectation into your dashboard with a last-updated timestamp so event managers know when data becomes available. - Implement no-show calculation by comparing registrant emails against attendee emails in a JavaScript query — this segment is valuable for re-engagement campaigns and should be an explicit view in your attendee management panel. - For the post-event CRM sync workflow, always match on email address as the join key rather than display name — Webex allows users to change their display names, but email is a reliable identifier across Webex and CRM systems. - Monitor Webex API rate limits when building event dashboards that pull registrant and attendee data for many events simultaneously — implement query caching and avoid polling endpoints more frequently than every 5 minutes for live event monitoring. ## Use cases ### Build an event registration and attendance tracker Create a Retool dashboard that lists all upcoming and past Webex events, showing registration count, event capacity, attendee rate (actual attendees divided by registrants), and average join time. Event managers can click into any event to see the full registrant list, filter by attendee status (registered, attended, no-show), and export the filtered list for follow-up campaigns. A heat map chart shows attendance patterns by hour of day to optimize future event scheduling. Prompt example: ``` Build an event tracker that queries GET /events from Webex API, displays events in a Table with title, start_time, registrant_count, attendee_count, attendance_rate, and status. Clicking a row loads registrant details via GET /events/{id}/registrants. Add status filter buttons (All, Attended, No-Show) and an export button that downloads the filtered list as CSV. ``` ### Attendee CRM sync panel with follow-up workflow Build a Retool app that fetches completed Webex event attendees and matches them against your internal CRM database by email address. The panel shows which attendees are existing CRM contacts (marked green) and which are new leads (marked yellow). Marketing coordinators can select new leads and click 'Add to CRM' to trigger a batch import, or select high-engagement attendees (based on session duration or poll responses) to add to a priority follow-up list in your CRM. Prompt example: ``` Create an attendee sync panel that fetches Webex event attendees for a selected event and joins them with the CRM contacts table (PostgreSQL resource) by email. Display matched contacts and unmatched new leads in separate Table sections. Add an 'Import New Leads' button that loops through unmatched attendees and POSTs each as a new contact to the CRM API resource. ``` ### Live event monitoring dashboard Build a real-time Retool dashboard for event coordinators to monitor a live Webex event in progress. The dashboard polls the Webex API every 30 seconds to show current attendee count, peak attendance, participant join/leave timestamps, and Q&A engagement metrics. A chart updates in near-real-time showing the attendance curve over the event duration. A Slack integration button lets coordinators send mid-event updates to a marketing Slack channel. Prompt example: ``` Build a live event monitor that polls GET /meetings/{meetingId}/attendees every 30 seconds (auto-refresh enabled), displays current_attendee_count in a large Stat component, and shows a line Chart of attendance count over time (using Retool's event handler to append new data points to a local state variable on each poll). Add a 'Post to Slack' button that sends the current attendance count to a Slack channel. ``` ## Troubleshooting ### GET /meetings returns an empty items array or does not include webinar-type events Cause: The meetingType=webinar parameter may not be supported for your Webex plan, or your events are classified as 'largeMeetings' rather than 'webinars' depending on your Webex account tier. Solution: Try the query without the meetingType filter first to see all meeting types returned. Also try meetingType=scheduledMeeting and meetingType=personalRoomMeeting to identify what types your account uses. For Webex Events specifically, check if your account uses the /events endpoint versus /meetings — run both and compare the responses to determine where your event data lives. ### Registrants endpoint returns 404 or 'Meeting not found' for a valid meeting ID Cause: Not all meeting types support registration — only Webex Webinars and events configured with 'Require Registration' enabled have registrant data accessible via the /meetings/{id}/registrants endpoint. Solution: Confirm the meeting has registration enabled by checking the meeting's 'requireRegistration' field in the meetings list response. For standard meetings without registration, use the /meetings/{id}/attendees endpoint which returns participants who joined directly without a formal registration step. ### Attendees query returns data for live events but shows empty after the event ends Cause: Webex may move attendee data to a separate post-meeting report endpoint after the event ends, or there may be a processing delay before post-event data is available via the API. Solution: Allow 15-30 minutes after an event ends before querying attendee data — Webex processes attendance reports after the event concludes. Also check if post-event data is available via a different path: try GET /meetings/{id}/attendees?hostEmail={host} or check if your account requires accessing recording/attendance reports through the Webex Control Hub API rather than the standard meetings API. ### Webex Webhook does not trigger the Retool Workflow when a meeting ends Cause: The Webex Webhook may not have been created with the correct resource ('meetings') and event ('ended') combination, or the targetUrl may not be accessible from Webex's servers, or the webhook was created with an expired token that has since been invalidated. Solution: In the Webex developer portal, verify your webhook configuration using GET /webhooks — check that the webhook shows status 'active', resource='meetings', event='ended', and the targetUrl matches your Retool Workflow's webhook URL exactly. If the status is inactive, delete and recreate the webhook. Ensure the Retool Workflow is in 'Published' state (not just saved) for the webhook endpoint to be active. ## Frequently asked questions ### Does a Webex Bot token give access to all events in an organization, or only events the Bot hosts? A Webex Bot token allows access to events and meetings that the Bot is either hosting or has been invited to as a co-host or attendee. For organization-wide event data (all events hosted by any user in the org), you need a Webex Integration with admin-level OAuth scopes or a Webex Control Hub admin token — contact your Webex admin for the appropriate credentials and scope access. ### Can Retool access Webex Events attendee data in real time during a live event? Yes, the /meetings/{id}/attendees endpoint returns current participant data for an in-progress event. Set your Retool query to auto-refresh every 30 seconds using Retool's 'Refresh query every X seconds' setting to simulate real-time monitoring. Note that Webex may impose rate limits on polling frequency — stay at 30-60 second intervals to avoid 429 errors. ### How do I export the attendee list from a Webex Event to a CSV file using Retool? Enable the 'Download as CSV' option on the attendees Table component in Retool (right-click a column header and look for export options), or create a JavaScript query that converts attendeesQuery.data to a CSV string and triggers a file download using Retool's utils.downloadFile() function. The CSV includes all columns displayed in your transformer output. ### What is the difference between the /events and /meetings endpoints in the Webex API? The Webex /events endpoint returns audit-type events (messages sent, memberships created, files uploaded) in Webex Spaces — these are not meeting events. For Webex Webinar and large meeting data with registrants and attendees, use the /meetings endpoint with meetingType=webinar or meetingType=scheduledMeeting. The naming is confusing but the two endpoints serve entirely different purposes. ### Can I send confirmation emails to registrants directly from Retool using the Webex API? Webex handles registration confirmation emails automatically when users register for a webinar — you cannot suppress or customize these via the API. For custom follow-up emails (post-event thank you, no-show re-engagement), use a separate email resource in Retool (SendGrid, Mailchimp, or SMTP) combined with the attendee list from the Webex API. Webex's API does not expose an email-sending endpoint for event communications. --- Source: https://www.rapidevelopers.com/retool-integrations/webex-events © RapidDev — https://www.rapidevelopers.com/retool-integrations/webex-events
