Clay Rate Limits

Overview

Clay enforces rate limits at the plan level, webhook level, and enrichment provider level. Understanding these limits prevents data loss, credit waste, and integration failures.

Prerequisites

• Clay account with known plan tier
• Webhook URL(s) for your tables
• Understanding of your data volume requirements

Instructions

Step 1: Understand Clay Rate Limit Tiers

Key insight: The 50K webhook submission limit is per-webhook, not per-table. Once exhausted, create a new webhook on the same table.

Step 2: Implement Webhook Rate Limiting

// src/clay/rate-limiter.ts — respect Clay's plan-level rate limits
import PQueue from 'p-queue';

interface RateLimiterConfig {
  maxPerHour: number;     // Plan limit (e.g., 400 for Explorer)
  maxPerSecond: number;   // Practical burst limit
  webhookLimit: number;   // 50K per webhook lifetime
}

const PLAN_LIMITS: Record<string, RateLimiterConfig> = {
  explorer: { maxPerHour: 400, maxPerSecond: 2, webhookLimit: 50_000 },
  pro:      { maxPerHour: Infinity, maxPerSecond: 10, webhookLimit: 50_000 },
  enterprise: { maxPerHour: Infinity, maxPerSecond: 20, webhookLimit: 50_000 },
};

class ClayRateLimiter {
  private queue: PQueue;
  private submissionCount = 0;
  private hourlyCount = 0;
  private hourlyResetAt: Date;
  private config: RateLimiterConfig;

  constructor(plan: keyof typeof PLAN_LIMITS) {
    this.config = PLAN_LIMITS[plan];
    this.queue = new PQueue({
      concurrency: 1,
      interval: 1000,
      intervalCap: this.config.maxPerSecond,
    });
    this.hourlyResetAt = new Date(Date.now() + 3600_000);
  }

  async submit(webhookUrl: string, data: Record<string, unknown>): Promise<Response> {
    // Check webhook lifetime limit
    if (this.submissionCount >= this.config.webhookLimit) {
      throw new Error(
        `Webhook submission limit (${this.config.webhookLimit}) reached. Create a new webhook.`
      );
    }

    // Check hourly limit
    if (Date.now() > this.hourlyResetAt.getTime()) {
      this.hourlyCount = 0;
      this.hourlyResetAt = new Date(Date.now() + 3600_000);
    }
    if (this.hourlyCount >= this.config.maxPerHour) {
      const waitMs = this.hourlyResetAt.getTime() - Date.now();
      console.log(`Hourly limit reached. Waiting ${(waitMs / 1000).toFixed(0)}s...`);
      await new Promise(r => setTimeout(r, waitMs));
      this.hourlyCount = 0;
    }

    return this.queue.add(async () => {
      const res = await fetch(webhookUrl, {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify(data),
      });

      if (res.status === 429) {
        const retryAfter = parseInt(res.headers.get('Retry-After') || '60');
        console.log(`429 rate limited. Waiting ${retryAfter}s...`);
        await new Promise(r => setTimeout(r, retryAfter * 1000));
        return this.submit(webhookUrl, data); // Retry
      }

      this.submissionCount++;
      this.hourlyCount++;
      return res;
    });
  }

  getStats() {
    return {
      totalSubmissions: this.submissionCount,
      hourlyRemaining: this.config.maxPerHour - this.hourlyCount,
      webhookRemaining: this.config.webhookLimit - this.submissionCount,
    };
  }
}

Step 3: Handle 429 Responses with Backoff

// src/clay/backoff.ts
async function withClayBackoff<T>(
  operation: () => Promise<T>,
  maxRetries = 5
): Promise<T> {
  for (let attempt = 0; attempt <= maxRetries; attempt++) {
    try {
      return await operation();
    } catch (error: any) {
      if (attempt === maxRetries) throw error;

      // Clay returns 429 for plan-level rate limits
      const status = error.status || error.response?.status;
      if (status !== 429 && (status < 500 || status >= 600)) throw error;

      const baseDelay = 1000 * Math.pow(2, attempt); // 1s, 2s, 4s, 8s, 16s
      const jitter = Math.random() * 500;
      const delay = Math.min(baseDelay + jitter, 60_000); // Max 60s

      console.log(`Clay rate limited (attempt ${attempt + 1}). Retrying in ${(delay / 1000).toFixed(1)}s`);
      await new Promise(r => setTimeout(r, delay));
    }
  }
  throw new Error('Unreachable');
}

Step 4: Manage Webhook Lifecycle

// src/clay/webhook-manager.ts
interface WebhookState {
  url: string;
  submissionCount: number;
  createdAt: Date;
}

class WebhookManager {
  private webhooks: Map<string, WebhookState> = new Map();
  private readonly LIMIT = 50_000;
  private readonly WARN_THRESHOLD = 45_000;

  registerWebhook(tableId: string, url: string) {
    this.webhooks.set(tableId, { url, submissionCount: 0, createdAt: new Date() });
  }

  async getWebhookUrl(tableId: string): Promise<string> {
    const state = this.webhooks.get(tableId);
    if (!state) throw new Error(`No webhook registered for table ${tableId}`);

    if (state.submissionCount >= this.LIMIT) {
      throw new Error(
        `Webhook for table ${tableId} exhausted (${this.LIMIT} submissions). ` +
        `Create a new webhook in Clay UI: Table > + Add > Webhooks > Monitor webhook`
      );
    }

    if (state.submissionCount >= this.WARN_THRESHOLD) {
      console.warn(
        `Webhook for ${tableId} at ${state.submissionCount}/${this.LIMIT} submissions. ` +
        `Plan to create a replacement soon.`
      );
    }

    return state.url;
  }

  recordSubmission(tableId: string) {
    const state = this.webhooks.get(tableId);
    if (state) state.submissionCount++;
  }
}

Step 5: Enrichment Provider Rate Limits

Enrichment providers within Clay have their own limits. When using Clay's managed accounts, Clay handles throttling internally. When using your own API keys, you inherit the provider's rate limits:
