Cmdlet Tips

BookingBusinessId: It’s crucial to use the correct BookingBusinessId rather than the BusinessId to ensure accurate data retrieval.
Filtering: When using the -Filter parameter, ensure that the datetime values are in ISO 8601 format (YYYY-MM-DDTHH:MM:SSZ) as improper formatting may result in errors.

Possible Errors & Solutions

Error 1: InvalidAuthenticationToken

Cause: The access token used is invalid or expired.

Solution: Re-authenticate by running Connect-MgGraph to obtain a new token.

Error 2: Request_BadRequest

Cause: This error typically occurs when the filter criteria are incorrect, such as improper date formatting.

Solution: Ensure the filter values, especially datetime, are in the correct ISO 8601 format. Review the filter syntax and correct any mistakes.

Error 3: ResourceNotFound

Cause: The specified BookingBusinessId does not exist, or the user does not have permission to access it.

Solution: Verify that the BookingBusinessId is correct and that the user has appropriate permissions.

Use Cases

Appointment Tracking: Retrieve appointments for reporting and auditing purposes.
Customer Insights: Analyze booking data to gain insights into customer behavior and preferences.
Integration: Integrate booking data with other business systems for enhanced functionality and automation.
