Workflow examples

Complete workflows, adapted from ones the Whenever team runs. Each passes the real build as printed here: copy one, swap the config names for your own, and connect the products it calls.

Sweep an inbox every hour

An interval trigger, a bound Gmail search that pages until it is done, and a batched write.

TypeScript
import {
  defineStep,
  defineWorkflow,
  every,
  manual,
  NonRetryableError,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';

export const manifest: WorkflowManifest = {
  name: 'Mark notifier emails as read',
  triggers: [every('1h', { key: 'hourly-sweep' }), manual({ key: 'sweep-now' })],
};

export const findUnreadMessages = defineStep(
  'Find unread notifier emails',
  async (ctx: WorkflowContext) => {
    const ids: string[] = [];
    let pageToken: string | undefined;
    do {
      const page = await ctx.integrations.gmail.fetchEmails({
        user_id: 'me',
        query: `from:${ctx.config.NOTIFIER_ADDRESS} is:unread`,
        ids_only: true,
        max_results: 500,
        ...(pageToken ? { page_token: pageToken } : {}),
      });
      for (const message of page.messages ?? []) {
        if (!message.messageId) {
          throw new NonRetryableError('Gmail returned a message without an identifier');
        }
        ids.push(message.messageId);
      }
      pageToken = page.nextPageToken || undefined;
    } while (pageToken);
    return ids;
  },
);

export const markMessagesRead = defineStep(
  'Mark notifier emails as read',
  async (ctx: WorkflowContext, ids: string[]) => {
    const results = [];
    // batchModifyMessages accepts at most 1,000 ids per call.
    for (let offset = 0; offset < ids.length; offset += 1000) {
      const result = await ctx.integrations.gmail.batchModifyMessages({
        userId: 'me',
        messageIds: ids.slice(offset, offset + 1000),
        removeLabelIds: ['UNREAD'],
      });
      if (!result.success) {
        throw new NonRetryableError('Gmail did not confirm a batch was marked read');
      }
      results.push(result);
    }
    return results;
  },
);

export default defineWorkflow<
  void,
  { marked: number; results: Awaited<ReturnType<typeof markMessagesRead>> }
>(async (ctx) => {
  const ids = await findUnreadMessages(ctx);
  const results = await markMessagesRead(ctx, ids);
  return { marked: ids.length, results };
});

every('1h', { key }) fires on the hour, and manual({ key }) beside it lets you run the same code on demand. The sender to sweep is a ctx.config value, so the owner sets it in Setup and the source never names a person. The write checks Gmail's own success flag before counting a batch as done.

A daily analytics digest

Reads every Google Analytics property under one account, then posts the digest to Slack and emails it.

TypeScript
import {
  daily,
  defineStep,
  defineWorkflow,
  NonRetryableError,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';

export const manifest: WorkflowManifest = {
  name: 'Google Analytics digest to Slack and Gmail',
  triggers: [daily({ key: 'morning-digest', at: '09:00', tz: 'UTC' })],
};

type Property = { property: string; name: string };

function utcDay(date: Date): string {
  return date.toISOString().slice(0, 10);
}

export const findProperties = defineStep(
  'Find Analytics properties',
  async (ctx: WorkflowContext) => {
    const properties: Property[] = [];
    let pageToken: string | undefined;
    do {
      const page = await ctx.integrations.google_analytics.listAccountSummaries(
        pageToken ? { pageToken } : {},
      );
      for (const account of page.accountSummaries ?? []) {
        if (account.account !== `accounts/${ctx.config.GOOGLE_ANALYTICS_ACCOUNT_ID}`) continue;
        for (const property of account.propertySummaries ?? []) {
          if (property.property) {
            properties.push({
              property: property.property,
              name: property.displayName ?? property.property,
            });
          }
        }
      }
      pageToken = page.nextPageToken;
    } while (pageToken);
    if (properties.length === 0) {
      throw new NonRetryableError(
        'No Analytics properties are visible under the configured account',
      );
    }
    return properties;
  },
);

export const readLastSevenDays = defineStep(
  'Read the last seven complete days',
  async (ctx: WorkflowContext, properties: Property[]) => {
    const now = new Date(ctx.now());
    const today = Date.UTC(now.getUTCFullYear(), now.getUTCMonth(), now.getUTCDate());
    const startDate = utcDay(new Date(today - 7 * 86_400_000));
    const endDate = utcDay(new Date(today - 86_400_000));
    const lines: string[] = [];
    for (const item of properties) {
      const report = await ctx.integrations.google_analytics.runReport({
        property: item.property,
        dateRanges: [{ startDate, endDate }],
        metrics: [{ name: 'activeUsers' }, { name: 'sessions' }, { name: 'screenPageViews' }],
      });
      // An explicit rowCount of 0 is a quiet week; a missing row without it is not evidence of one.
      const values =
        report.rowCount === 0
          ? ['0', '0', '0']
          : report.rows?.[0]?.metricValues?.map((metric) => metric.value);
      if (!values || values.length !== 3 || values.some((value) => value === undefined)) {
        throw new NonRetryableError(`Incomplete seven-day report for ${item.name}`);
      }
      lines.push(
        `• *${item.name}* — users ${values[0]} · sessions ${values[1]} · views ${values[2]}`,
      );
    }
    return `*Google Analytics, ${startDate} to ${endDate} (UTC)*\n${lines.join('\n')}`;
  },
);

export const postToSlack = defineStep(
  'Post digest to Slack',
  async (ctx: WorkflowContext, digest: string) => {
    const response = await ctx.integrations.http.post({
      url: 'https://slack.com/api/chat.postMessage',
      headers: { Authorization: `Bearer ${ctx.secrets.SLACK_BOT_TOKEN}` },
      body: { channel: ctx.config.SLACK_CHANNEL_ID, text: digest },
    });
    const body = response.body;
    if (typeof body !== 'object' || body === null || !('ok' in body) || body.ok !== true) {
      throw new NonRetryableError('Slack did not accept the message', {
        detail:
          typeof body === 'object' &&
          body !== null &&
          'error' in body &&
          typeof body.error === 'string'
            ? body.error
            : undefined,
        operation: 'chat.postMessage',
      });
    }
    return response;
  },
);

export const emailDigest = defineStep(
  'Email digest',
  async (ctx: WorkflowContext, digest: string) => {
    return await ctx.integrations.gmail.sendEmail({
      recipient_email: 'me',
      subject: 'Google Analytics — last 7 complete days',
      body: digest.replace(/[*_]/g, ''),
    });
  },
);

export default defineWorkflow<
  void,
  {
    digest: string;
    slack: Awaited<ReturnType<typeof postToSlack>>;
    email: Awaited<ReturnType<typeof emailDigest>>;
  }
>(async (ctx) => {
  const properties = await findProperties(ctx);
  const digest = await readLastSevenDays(ctx, properties);
  const slack = await postToSlack(ctx, digest);
  const email = await emailDigest(ctx, digest);
  return { digest, slack, email };
});

A schedule hands the run no input, so the date range comes from ctx.now() rather than from ctx.input. A report with an explicit row count of zero is a quiet week; a report with no rows and no count is incomplete, and the step throws rather than posting zeros it cannot vouch for. The Slack token is a workflow secret; Gmail and Analytics are connections the owner grants in Setup.

Announce new contacts in Slack

A plain inbound webhook, for any service that can POST JSON to a URL.

TypeScript
import {
  defineStep,
  defineWorkflow,
  NonRetryableError,
  webhook,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';

export const manifest: WorkflowManifest = {
  name: 'Announce new contacts in Slack',
  triggers: [webhook({ key: 'contact-created', name: 'New contact' })],
};

type ContactInput = Record<string, unknown> | null | undefined;

export const announceContact = defineStep(
  'Post new contact to Slack',
  async (ctx: WorkflowContext<ContactInput>, email: string) => {
    const result = await ctx.integrations.http.post({
      url: 'https://slack.com/api/chat.postMessage',
      headers: { Authorization: `Bearer ${ctx.secrets.SLACK_BOT_TOKEN}` },
      body: { channel: ctx.config.SLACK_CHANNEL_ID, text: `New contact: ${email}` },
    });
    const body = result.body;
    if (typeof body !== 'object' || body === null || !('ok' in body) || body.ok !== true) {
      throw new NonRetryableError('Slack did not confirm the notification');
    }
    return result;
  },
);

export default defineWorkflow<
  ContactInput,
  Awaited<ReturnType<typeof announceContact>> | { ignored: string }
>(async (ctx) => {
  const input = ctx.input;
  // The endpoint is unverified, so anything can arrive: accept only the shape you expect.
  if (input === null || input === undefined) return { ignored: 'empty delivery' };
  const data = input.data;
  if (
    typeof data !== 'object' ||
    data === null ||
    !('contactEmail' in data) ||
    typeof data.contactEmail !== 'string' ||
    data.contactEmail.trim() === ''
  ) {
    throw new NonRetryableError('The delivery carries no data.contactEmail');
  }
  return await announceContact(ctx, data.contactEmail);
});

webhook({ key }) checks no signature, so treat every body as untrusted: narrow it before reading a field, and ignore what you do not expect. The key is the endpoint's identity; keep it fixed and the URL stays the same across edits.

Log Discord app installs

A sender helper verifies each delivery, and the run branches on the sender's own event name.

TypeScript
import {
  defineStep,
  defineWorkflow,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';
import { discordAppEventsWebhook } from '@wix/whenever-workflow-sdk/webhooks';

type AuthorizationInput = {
  application_id: string;
  event: {
    type: 'APPLICATION_AUTHORIZED';
    timestamp: string;
    data: {
      user: { id: string; username: string };
      scopes: string[];
      guild?: { id: string; name: string };
    };
  };
};

type Authorization = {
  user: { id: string; username: string };
  server: string | null;
  scopes: string[];
};

export const manifest: WorkflowManifest = {
  name: 'Log Discord app installs',
  triggers: [discordAppEventsWebhook({ key: 'discord-app-events' })],
};

export const logAuthorization = defineStep(
  'Log Discord app authorization',
  async (ctx: WorkflowContext<AuthorizationInput>): Promise<Authorization> => {
    const { user, guild, scopes } = ctx.input.event.data;
    const authorization = {
      user: { id: user.id, username: user.username },
      server: guild?.name ?? null,
      scopes,
    };
    ctx.log('Discord app authorized', authorization);
    return authorization;
  },
);

export default defineWorkflow<AuthorizationInput, Authorization | { ignored: string }>(
  async (ctx) => {
    if (ctx.trigger.eventType !== 'APPLICATION_AUTHORIZED')
      return { ignored: 'not an authorization' };
    return await logAuthorization(ctx);
  },
);

discordAppEventsWebhook comes from @wix/whenever-workflow-sdk/webhooks. The platform checks Discord's signature with the app's public key from Setup before the run starts, and ctx.trigger.eventType carries Discord's event name. A workflow that only reads and logs needs no connected product at all.

Reply on WhatsApp

Answers every incoming WhatsApp message with a quote of the day, through the Cloud API.

TypeScript
import {
  defineStep,
  defineWorkflow,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';
import { metaAppWhatsAppWebhook } from '@wix/whenever-workflow-sdk/webhooks';

type WhatsAppInput = {
  object: 'whatsapp_business_account';
  entry: Array<{
    id: string;
    changes: Array<{
      field: 'messages';
      value: {
        metadata: { display_phone_number: string; phone_number_id: string };
        messages?: Array<{ from: string; id: string; type: string; text?: { body: string } }>;
      };
    }>;
  }>;
};

export const manifest: WorkflowManifest = {
  name: 'WhatsApp quote of the day',
  triggers: [metaAppWhatsAppWebhook({ key: 'whatsapp-messages' })],
};

const quotes = [
  'Small steps still take you somewhere.',
  'Give your attention to what you can grow today.',
  'A little progress is a reason to keep going.',
  'Rest is part of moving forward.',
];

export const replyWithQuote = defineStep(
  "Reply with today's quote",
  async (
    ctx: WorkflowContext<WhatsAppInput>,
    to: string,
    phoneNumberId: string,
    messageId: string,
    quote: string,
  ) => {
    return await ctx.integrations.http.post({
      url: `https://graph.facebook.com/${ctx.config.GRAPH_API_VERSION}/${phoneNumberId}/messages`,
      headers: { Authorization: `Bearer ${ctx.secrets.WHATSAPP_ACCESS_TOKEN}` },
      body: {
        messaging_product: 'whatsapp',
        to,
        type: 'text',
        text: { body: `Quote of the day: “${quote}”` },
        context: { message_id: messageId },
      },
    });
  },
);

type Receipt = Awaited<ReturnType<typeof replyWithQuote>>;

export default defineWorkflow<WhatsAppInput, { replies: Receipt[] }>(async (ctx) => {
  const quote = quotes[Math.floor(ctx.now() / 86_400_000) % quotes.length]!;
  const replies: Receipt[] = [];
  for (const entry of ctx.input.entry) {
    for (const change of entry.changes) {
      for (const message of change.value.messages ?? []) {
        replies.push(
          await replyWithQuote(
            ctx,
            message.from,
            change.value.metadata.phone_number_id,
            message.id,
            quote,
          ),
        );
      }
    }
  }
  return { replies };
});

metaAppWhatsAppWebhook runs only for deliveries that carry messages; status receipts never start a run. The reply goes out through http.post with the access token from ctx.secrets, and the run returns Meta's receipt for each reply, which records that Meta accepted the message, not that it was delivered.

One workflow, a webhook and five schedules

Records issue events as they arrive, and posts yesterday's totals every weekday morning.

TypeScript
import {
  defineStep,
  defineWorkflow,
  NonRetryableError,
  webhook,
  weekly,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';

export const manifest: WorkflowManifest = {
  name: 'Weekday issue report',
  triggers: [
    webhook({ key: 'issue-events' }),
    weekly({ key: 'report-monday', day: 'monday', at: '08:30', tz: 'Europe/Vilnius' }),
    weekly({ key: 'report-tuesday', day: 'tuesday', at: '08:30', tz: 'Europe/Vilnius' }),
    weekly({ key: 'report-wednesday', day: 'wednesday', at: '08:30', tz: 'Europe/Vilnius' }),
    weekly({ key: 'report-thursday', day: 'thursday', at: '08:30', tz: 'Europe/Vilnius' }),
    weekly({ key: 'report-friday', day: 'friday', at: '08:30', tz: 'Europe/Vilnius' }),
  ],
};

type Input = Record<string, unknown> | void;
type Report = { day: string; opened: number; closed: number };

const vilnius = new Intl.DateTimeFormat('en-CA', { timeZone: 'Europe/Vilnius' });
const localDay = (value: number | string) => vilnius.format(new Date(value));

// Monday reports on Friday; every other weekday reports on the day before.
function reportDay(now: number, monday: boolean): string {
  const day = new Date(`${localDay(now)}T00:00:00Z`);
  day.setUTCDate(day.getUTCDate() - (monday ? 3 : 1));
  return day.toISOString().slice(0, 10);
}

export const recordEvent = defineStep(
  'Record issue event',
  async (ctx: WorkflowContext<Input>, day: string, action: 'opened' | 'closed', number: number) => {
    return await ctx.integrations.googlesheets.spreadsheetsValuesAppend({
      spreadsheetId: ctx.config.REPORT_SPREADSHEET_ID,
      range: 'Events!A:D',
      valueInputOption: 'RAW',
      values: [[day, action, number, ctx.trigger.deliveryId ?? '']],
    });
  },
);

export const countEvents = defineStep(
  'Count yesterday’s events',
  async (ctx: WorkflowContext<Input>) => {
    const day = reportDay(ctx.now(), ctx.trigger.key === 'report-monday');
    const read = await ctx.integrations.googlesheets.valuesGet({
      spreadsheet_id: ctx.config.REPORT_SPREADSHEET_ID,
      range: 'Events!A:B',
    });
    let opened = 0;
    let closed = 0;
    for (const row of read.values ?? []) {
      if (row[0] !== day) continue;
      if (row[1] === 'opened') opened++;
      if (row[1] === 'closed') closed++;
    }
    return { day, opened, closed };
  },
);

export const postReport = defineStep(
  'Post report to Slack',
  async (ctx: WorkflowContext<Input>, report: Report) => {
    const sent = await ctx.integrations.http.post({
      url: 'https://slack.com/api/chat.postMessage',
      headers: { Authorization: `Bearer ${ctx.secrets.SLACK_BOT_TOKEN}` },
      body: {
        channel: ctx.config.SLACK_CHANNEL_ID,
        text: `Issues on ${report.day}: ${report.opened} opened, ${report.closed} closed.`,
      },
    });
    if (
      typeof sent.body !== 'object' ||
      sent.body === null ||
      !('ok' in sent.body) ||
      sent.body.ok !== true
    ) {
      throw new NonRetryableError('Slack did not accept the report');
    }
    return sent;
  },
);

export default defineWorkflow<
  Input,
  | { event: Awaited<ReturnType<typeof recordEvent>> }
  | { report: Report; slack: Awaited<ReturnType<typeof postReport>> }
  | { ignored: string }
>(async (ctx) => {
  if (ctx.trigger.type === 'webhook') {
    const input = ctx.input;
    if (typeof input !== 'object' || input === null) return { ignored: 'empty delivery' };
    const issue = input.issue;
    if (
      typeof issue !== 'object' ||
      issue === null ||
      !('number' in issue) ||
      typeof issue.number !== 'number'
    ) {
      throw new NonRetryableError('The issues event has no issue number');
    }
    if (
      input.action === 'opened' &&
      'created_at' in issue &&
      typeof issue.created_at === 'string'
    ) {
      return { event: await recordEvent(ctx, localDay(issue.created_at), 'opened', issue.number) };
    }
    if (input.action === 'closed' && 'closed_at' in issue && typeof issue.closed_at === 'string') {
      return { event: await recordEvent(ctx, localDay(issue.closed_at), 'closed', issue.number) };
    }
    return { ignored: 'neither opened nor closed' };
  }
  const report = await countEvents(ctx);
  const slack = await postReport(ctx, report);
  return { report, slack };
});

Every trigger carries its own key, and the run reads the one that fired from ctx.trigger: type tells the webhook path from the scheduled one, and key tells Monday, which reports on Friday, from the other weekdays. The webhook's deliveryId goes into the sheet with each event, so a delivery recorded twice can be told apart from two events.

A Telegram assistant with tools

The model decides which read-only tool to call; the workflow runs each call and loops until it has an answer.

TypeScript
import {
  defineStep,
  defineWorkflow,
  NonRetryableError,
  type AiMessage,
  type WorkflowContext,
  type WorkflowManifest,
} from '@wix/whenever-workflow-sdk';
import { telegramBotWebhook } from '@wix/whenever-workflow-sdk/webhooks';

ai.generateText with messages and tools is one turn of a conversation. On finishReason: 'tool-calls' the workflow appends the model's message, runs each call through its own step, and answers with a tool message per call. The platform keeps no conversation and never runs a tool itself, so the loop, its turn cap and the argument checks are all in your code. The chat check matters too: this bot reads its owner's inbox, so it answers only the owner's private chat — a group id would let every member in.

What every example assumes

Each ctx.integrations.<product>.<operation> call other than http, mcp, ai and postgres exists only after you bind that operation, and runs only once the owner connects the product. Every ctx.config.NAME and ctx.secrets.NAME the source spells out becomes a value the owner fills in Setup before the workflow can publish. A coding agent connected to the Whenever MCP server does both: it binds each operation it writes, and hands the owner the one Setup link the rest needs.
