DROPCONTACT 250 BATCH ASYNCHRONOUSLY
Key Features and Highlights
This workflow implements batch asynchronous calls to the Dropcontact API for contact information enrichment, supporting up to 1,500 requests per hour, significantly enhancing data processing efficiency. It incorporates built-in data aggregation and transformation logic to ensure the data format complies with API requirements. By processing requests in batches with controlled waiting nodes, it effectively manages request rates to prevent API rate limit breaches. Error retry mechanisms and Slack alert notifications ensure workflow stability and real-time exception monitoring.
Core Problems Addressed
- Automatically filters target contact records from the database based on criteria (e.g., contacts with the position "Bestuurder" and missing email information).
- Efficiently performs batch calls to the Dropcontact API to enrich missing email and phone details.
- Prevents request rate limit violations through batch segmentation and asynchronous wait controls.
- Automatically updates enrichment results back into the Postgres database to keep data current.
- Captures and alerts on any Dropcontact API usage anomalies promptly.
Use Cases
- Periodic cleansing and enrichment of contact information in enterprise CRM or customer data platforms.
