This article describes how to utilize the PDF Scout™ Inspector Tool API to check or pre-flight PDF files.
- PDF files are uploaded to Scout.
- A Scout process will analyze the PDF for pre-configured checks such as file size, known corrupted PDF data, page dimensions, etc
- Scout results are available via the url /api/scout (POST) in json format
Scout checks are required before PDF files can be used for plan review in EPR.
Best Practices
e-PlanREVIEW® (EPR) will not accept plan review documents rejected by Scout. All plan review documents must be submitted in PDF format.
