Ideas for Marketing or Automation

• Build Birthday Campaigns (clients with upcoming birthdays)

• Send Loyalty Rewards (clients with completed_visits >= 10)

• Remind inactive clients (e.g., "last_visit_before": "2023-01-01")

• Create birthday campaigns (extend API with birthday field if needed)

• Target VIP clients who spend more frequently

• Export segmented client lists to Mailchimp or any email platform

• Trigger SMS via Twilio for last-minute promos

Notes

• Important: for polling-based setup, all new records will be fetched together, which could lead to duplication unless filtered appropriately, please keep a record of those that have been contacted if you are using this for notifications

• dob_year, dob_month, and dob_day are separate fields.

• Search Behavior: The search field performs a partial match across first name, last name, email, and mobile phone.

• Dates must be in YYYY-MM-DD format.

• Pagination: Default per_page is 100 if not specified. Maximum allowed is 1000 per page.

• Rate Limiting: Please ensure reasonable usage to avoid throttling. It is recommended to poll no faster than once per minute.
