Hello Acumatica Community,
Starting in Acumatica 23r200 we plan to remove the 17.200 and 18.200 endpoints.
Please note that these are the last endpoints to support the SOAP API, so when it is removed integrations built using SOAP will no longer function..
We recommend updating solutions to use the latest endpoint, the REST API, and OData v4.
For more information see page 6 of the 23r2 Developer Release notes.
