Dear Customers, We would like to advise of a change affecting ArcGIS REST export requests that use map extent (bounding box) parameters.
What has changed? We have identified that some ArcGIS REST services may no longer recognise the uppercase parameter name: BBOX= and instead require the parameter to be specified in lowercase as: bbox= Requests using the uppercase parameter may fail or return errors indicating that the bounding box parameter has not been supplied.
Action required If you are constructing ArcGIS REST requests manually or through custom applications, scripts, integrations, or third-party clients, please ensure that the bounding box parameter is supplied using lowercase: Supported: bbox=,,, Not recommended: BBOX=,,,
Best practice To maximise compatibility with current and future ArcGIS releases, we recommend using the parameter names as documented by ESRI, including: • bbox • bboxSR • imageSR • size • dpi • format • layers • transparent • f
Further information Although there is no formal ESRI communication regarding this issue, the ArcGIS REST API documentation specifies the parameter as bbox (lowercase). While parameter names have historically been accepted in different cases by many ArcGIS services, customers should now use the documented lowercase parameter names to ensure consistent operation across ArcGIS environments. Our apologies for any inconveniences this may cause.
