Receiving 'Missing RapidAPI application key' Error despite providing key

I am currently working with RapidAPI, and when I attempt to make a POST request using Postman, I encounter an error message stating:

{
    "message": "Missing RapidAPI application key. Please consult the documentation to find out how to retrieve your API application key."
}

I have already included a RapidAPI application key in my POST request, which looks like this:

https://meetupdimashirokovv1.p.rapidapi.com/getEvents?x-rapidapi-host=XXXXXXXXXXXXXXXXXXXX&x-rapidapi-key=XXXXXXXXXXXXXXXXXXXX&content-type=application/x-www-form-urlencoded&accessToken=XXXXXXXXXXXXXXXXXXXX

Further, I attempted to create and use a new RapidAPI application key, but the issue persists. Can anyone help me troubleshoot this?

The 'Missing RapidAPI application key' error generally indicates that the API key is not being sent or not correctly recognized by the server. Here are some steps to troubleshoot the issue:

  1. Verify Key Placement: Ensure that the x-rapidapi-key is part of the HTTP headers and not the query parameters. Here’s how you can set it up in Postman:
    GET /getEvents HTTP/1.1
    Host: meetupdimashirokovv1.p.rapidapi.com
    x-rapidapi-key: YOUR_RAPIDAPI_KEY
    x-rapidapi-host: meetupdimashirokovv1.p.rapidapi.com
    content-type: application/x-www-form-urlencoded
    
  2. Check Key Validity: Double-check that the API key is active and correct by referencing your RapidAPI dashboard.
  3. Review Plan Restrictions: Sometimes limits or restrictions in your API subscription plan might affect key access.
  4. Network Interference: Check if there’s any network issue or firewall blocking outgoing requests that could lead to such errors.

By ensuring proper key placement, you can address this efficiently. If the problem persists, reaching out to RapidAPI support may provide further insights.

Make sure your API key is in the HTTP headers, not the URL. Try this setup:

POST /getEvents HTTP/1.1
Host: meetupdimashirokovv1.p.rapidapi.com
x-rapidapi-key: YOUR_RAPIDAPI_KEY
x-rapidapi-host: meetupdimashirokovv1.p.rapidapi.com
Content-Type: application/x-www-form-urlencoded

If that doesn’t work, double-check your key’s validity on RapidAPI and ensure no network issues are blocking requests. If needed, contact RapidAPI support.
