It stopped working on April 13 at noon. The request succeeds (200) but returns no data. The key is valid through August 2. I tried creating new keys including one with every privilege, but they don’t work either. I see the same behavior via the Python API using API keys, but the query works as expected with username password authentication. Two questions:</P><P>(1) Did something happen to the API on April 13? Or what could have changed with the feature layer?</P><P>(2) What is the right way to set up an api key for querying a feature service?</P> Sat, 13 Jun 2026 01:03:15 GMT https://community.esri.com/t5/arcgis-survey123-questions/api-key-stopped-working/m-p/1708011#M66396 GFA_Nonprofit 2026-06-13T01:03:15Z https://community.esri.com/t5/arcgis-survey123-questions/api-key-stopped-working/m-p/1709016#M66453 <P>Not sure if you saw this post.
