The Get a Customer's Information endpoint retrieves detailed information about a specific customer using their unique ID. This allows merchants to access and review customer data for management and operational purposes.

Key Features

Retrieve Specific Customer Details: Fetch all stored data for a specific customer by their customer_id.
Integration with Payment Methods: View a customer's associated payment methods using the Get all Payment Methods for a Customer endpoint.
Data for Updates: Retrieve data that can be used with the Update Customer Information or Delete a Customer endpoints.

Usage Notes

Required Parameter: The customer_id is mandatory to locate and fetch the customer record.

Payment Method Details: This endpoint does not include payment methods. Use the Get all Payment Methods for a Customer endpoint to retrieve them.

Use Case: Ideal for scenarios where detailed customer information is needed for review, updates, or integrations.

Response Structure

Code	Response	Description
200	Success	Returns the full customer record.
400	Bad Request	Invalid or missing `customer_id`.
401	Unauthorized	API key invalid or missing.
404	Not Found	No customer found with the provided `customer_id`.
500	Internal Server Error	An unexpected error occurred on the server.

Important Considerations

Customer Deletion: If the deleted_at field in the response is non-null, the customer has been soft-deleted and will not appear in general customer lists.
Data Completeness: Ensure the customer ID provided matches an existing record. A non-matching ID will result in a 404 response.
Data Sensitivity: Avoid exposing sensitive customer data in your application's front end.

Best Practices

Use this endpoint in conjunction with the Update Customer Information endpoint to maintain accurate records.
For operations involving payment methods, follow up this call with the Get all Payment Methods for a Customer endpoint.
Log or cache customer data judiciously to avoid repetitive API calls.
