The generated Reverse API client compiles, then the host sees the wrong characters

We generated a COBOL client for the new HTTP API. The call works and the text fields are garbled. Where do we look?

Look at the code page on the Reverse API client before you blame the new service. The client is generated from a Hub REVERSE project or from OpenAPI, and the host program calls out through OLREVAPI. Set the client type and URL for the environment that will run the program, regenerate if the contract changed, and compile again. Garbled text with a successful HTTP status is usually the code page, not the route.
