Converting camelCase operationId to user-friendly display names in RapidAPI interface

Other Questions RapidAPI

I’m working on setting up an API through the RapidAPI platform. When I import my OpenAPI specification file, the interface automatically uses the operationId values for display names in the navigation menu. The problem is that these IDs are typically in camelCase format, which doesn’t look great for end users.

Current situation:
My OpenAPI spec looks something like this:

paths:
  /books:
    get:
      summary: Retrieve all books
      operationId: getAllBooks
      tags:
        - library

The RapidAPI interface shows “getAllBooks” in the menu, but I want it to display “Retrieve all books” instead.

What I’ve tried:
I noticed that some APIs on RapidAPI have nice readable names like “Get User Profile” or “Search Products”. I’m wondering if there’s a specific field or configuration that tells RapidAPI to use the summary field instead of operationId for display purposes.

Question:
Is there a way to make RapidAPI use human-readable names in the web interface while keeping my operationId values in standard camelCase format? Maybe there’s an extension field or another property I should be using?

Had this same problem last year with my first API deployment on RapidAPI. Yeah, the platform uses the summary field for display names, but here’s the thing - it defaults to operationId when your summary’s missing or doesn’t pass their checks. Fixed mine by making sure every operation had a short summary with no special characters. Also validate your OpenAPI spec before importing - validation errors make RapidAPI ignore summaries completely. One more heads up: re-importing after changes doesn’t always update display names right away. You might need to create a new version or hit up their support to clear the cache.

Try the x-summary extension field if the regular summary isn’t working. RapidAPI’s parser gets weird with certain characters or length sometimes. I had luck changing my operationId to snake_case during import, then switching back - sounds dumb but it worked lol. Also check if your summary has quotes or special characters, that breaks their display logic.

RapidAPI should prioritize summary over operationId for display names, but it’s inconsistent. Here’s what’s worked for me: Keep summaries under 50 characters and use clear action-object patterns. “Get all books” works better than “Retrieve all books from the library database.” Use OpenAPI 3.0+ instead of Swagger 2.0 - I’ve seen better summary recognition with newer specs. If you’re still stuck, try adding x-rapidapi-name directly to your operation. It’s not officially documented but sometimes overrides the default behavior.
