What are webhooks?
Webhooks are event-driven triggers that automatically execute actions the moment something changes in your business systems.
Webhooks work like dominoes falling in sequence. When the first domino (event) falls, it automatically knocks down the next one, creating a chain reaction. When one event completes, it immediately triggers the next action without any manual intervention.
Simple webhooks explained example:
You’ve got a new deal in your CRM app => this triggered an update of your database in BigQuery => this triggered an email sending in Mailchimp, and so on.
Coupler.io’s webhook support enables event-triggered automation that connects your data flows to external workflows or triggers other data flows.
Understanding webhooks vs scheduled data refresh
The key difference between webhooks and scheduled updates is automation flow and immediacy.
Scheduled updates work like setting multiple alarms throughout the day—they execute regardless of whether anything has changed.
Webhooks work like a chain reaction—they only execute the next step when the triggering event actually occurs. This means faster responses, eliminated waiting time, and seamless workflow automation.
Here’s a real-world analogy: imagine you’re running a production line. You could have workers check every station every 15 minutes to see if the previous step is complete (scheduled updates).
Or you could set up an automatic system where completing one step immediately starts the next one (webhooks). The webhook approach creates continuous, efficient automation.
How do webhooks work in Coupler.io: Incoming vs. outgoing
Coupler.io supports both incoming and outgoing webhooks, giving you complete control over your event-driven automation workflows.
Incoming webhooks allow external systems to automatically trigger your Coupler.io data flows when specific events occur. When your CRM updates a lead status, your e-commerce platform processes a new order, or your marketing tool captures a new subscriber, these events can instantly execute data refresh in Coupler.io. This enables real-time data processing that automatically responds to business events rather than waiting for the next scheduled refresh.
Outgoing webhooks work in the opposite direction—they automatically trigger external actions when your Coupler.io data flows complete. After importing fresh sales data or updating customer records, Coupler.io can automatically execute follow-up workflows, trigger email campaigns, or run additional data processes. You can customize the webhook payload structure and add up to three different webhook URLs to any data flow. This enables you to initiate different automated actions, like executing subsequent data flows or triggering external business processes.
What you can do with Coupler.io webhooks
Here are the main ways you can use webhooks in Coupler.io to automate your data workflows:
1. Event-triggered data flows (Incoming webhooks)
Run your Coupler.io data flow instantly when something happens in an external system.
How it works: External system → Webhook trigger → Coupler.io data flow runs
Perfect for: Responding to business events in real-time instead of waiting for scheduled updates.
Real-world examples:
- New lead added to your CRM → Instantly runs your lead enrichment data flow in Coupler.io
- Order placed on Shopify → Immediately triggers your inventory update data flow
- Form submitted on website → Automatically executes your lead scoring data flow
- Payment received in Stripe → Instantly runs your financial reporting data flow
2. Sequential data flow automation
Build sophisticated automation sequences where completing one Coupler.io data flow automatically triggers the next one in your pipeline.
How it works: Data flow A completes → Triggers data flow B → Triggers data flow C (and so on)
Perfect for: Complex data processing ETL pipelines that need to run in a specific sequence.
Real-world examples:
- Customer data import completes → Triggers product usage analysis → Triggers customer health scoring → Triggers personalized marketing campaign updates
- Sales data refresh finishes → Triggers commission calculation → Triggers quarterly forecast update → Triggers executive dashboard refresh
- Support ticket analysis completes → Triggers customer satisfaction scoring → Triggers at-risk account identification → Triggers CS team notifications
3. Hybrid approach: Scheduled start + webhook chain
Combine the reliability of scheduled data flows with the flexibility of webhook automation for the most practical approach to complex data pipelines.
The problem this solves: Traditional scheduling requires guessing how long each data flow takes. If your 9:00 AM flow takes 20 minutes instead of 15, it breaks the timing for your 9:15 AM flow. You end up with complex scheduling (9:00 → 9:15 → 9:30 → 9:45) that falls apart when one step takes longer than expected.
How it works:
- Schedule only your first data flow (e.g., 9:00 AM daily)
- Configure webhooks to automatically trigger each subsequent flow when the previous one completes
- No matter how long each step takes, the chain continues seamlessly without timing conflicts
Perfect for: Complex data pipelines where you want predictable start times but flexible execution duration for each step.
Real-world examples:
- 9:00 AM: Customer data import from CRM (scheduled) → Triggers product usage analysis → Triggers customer health scoring → Triggers marketing campaign updates
- Daily financial reporting: 8:00 AM: Transaction data import (scheduled) → Triggers reconciliation process → Triggers cash flow analysis → Triggers executive dashboard update
- Weekly marketing analysis: Monday 10:00 AM: Campaign data import (scheduled) → Triggers performance analysis → Triggers ROI calculations → Triggers team reports
4. Report data flow status to the external system
Get instant notifications about your Coupler.io data flow status sent to any external system.
How it works: Data flow completes → Status webhook sent to external system → System receives success/failure notification.
Perfect for: Monitoring data flow execution and integrating status updates into your existing systems.
Real-world examples:
- Data flow finishes → Webhook notifies your monitoring dashboard about success/failure
- Import completes → Webhook updates your project management tool with execution status
- Processing fails → Webhook immediately alerts your team chat (Slack/Teams) with error details
- Scheduled report runs → Webhook confirms completion to your business intelligence platform
5. Data flow status reporting + JSON data export
Get notified when your data flow completes and automatically retrieve the processed data in JSON format.
How it works: Data flow completes → Status webhook sent to external system → If successful, JSON data retrieved
Perfect for: Applications that need both execution status and the actual processed data for further automation.
Real-world examples:
- Sales report finishes processing → Webhook notifies your dashboard app → App retrieves JSON data and updates visualizations
- Customer analysis completes → Webhook alerts your CRM system → CRM pulls JSON results and updates customer records
- Marketing campaign data processed → Webhook triggers your automation tool → Tool gets JSON data and launches targeted campaigns

Coupler.io users can generate a webhook for any data flow in their account via a straightforward process. Learn more about Coupler.io webhook support in our knowledge base.
For incoming webhooks (trigger data flows)
- Create a new data flow or open the existing one and go to the Flow settings => Webhooks.
- Generate a webhook using the respective button – this will create your unique webhook URL.
Once you’ve generated your data flow webhook URL, you can trigger the data flow run by sending a POST request to it.
For outgoing webhooks (data flows triggers external events):
- In your data flow settings, configure up to 3 different webhook URLs. These will get triggered when your data flow completes.
For sequential data flows:
- Generate incoming webhook URL for the data flow B that will be triggered by the data flow A.
- Use the generated webhook URL in the outgoing webhooks section of the data flow A.
- Chain multiple flows together for complex automation sequences.
Automate data flows and reporting with Coupler.io
Get started for freeEnsure your webhooks security
Webhooks create direct connections between systems, so proper security is essential to protect your data and maintain system integrity.
Coupler.io handles security on the platform side with:
- HTTPS encryption for all webhook URLs
- Properly configured authentication mechanisms
- SOC 2 compliance that meets enterprise-grade security standards
Coupler.io webhooks only transmit execution status, timestamps, and flow metadata. No actual data content is included in webhook payloads. This ensures your sensitive business information stays protected while still enabling automation workflows.
From the user side, treat webhook URLs as sensitive credentials:
- Never share webhook URLs publicly or include them in client-side code
- Store webhook URLs securely using environment variables or secret management systems
- Avoid logging webhook URLs in plain text logs or error messages
- Regularly rotate webhook URLs, especially if they may have been compromised
Beyond URL protection, implement additional security measures for your webhook endpoints. Set up proper authentication on receiving endpoints, monitor for webhook failures or unusual activity, and use rate limiting to prevent abuse. Always validate webhook payloads to ensure they match expected formats.
