I’m working with a RapidAPI service and running into a frustrating issue. Every time I make a POST request through Postman, I keep getting this error response:
{
"error": "RapidAPI application key is missing. Visit https://docs.rapidapi.com/docs/keys for information on obtaining your API key."
}
The weird part is that I’m definitely including my RapidAPI key in the request. Here’s how I’m structuring my API call:
https://eventfinderapi.p.rapidapi.com/fetchEvents?x-rapidapi-host=YYYYYYYYYYYYYYYY&x-rapidapi-key=YYYYYYYYYYYYYYYY&content-type=application/json&authToken=YYYYYYYYYYYYYYYY
I’ve already tried creating a brand new API key from my RapidAPI dashboard, but I’m still getting the same error. Has anyone else encountered this problem? What am I doing wrong here?
This exact error got me when I first started using RapidAPI. You’re putting the auth headers as query parameters in the URL instead of actual HTTP headers. Strip everything after the question mark from your URL - just keep the base endpoint. In Postman, add x-rapidapi-key and x-rapidapi-host as separate header entries. Content-type goes in headers too, not the URL. Fixed it instantly for me. Also double-check you’re copying the exact host value from the RapidAPI docs for that specific API.
had the same prob just a while ago! yeah, defo move those headers to the headers tab in postman, not url params. just keep your api call to the base endpoint. that solved it for me too!
The issue seems to stem from the placement of your RapidAPI headers. Instead of including them as URL parameters, they should be integrated into the HTTP headers. In Postman, you can do this by navigating to the Headers tab and adding ‘x-rapidapi-key’ with your API key and ‘x-rapidapi-host’ with the appropriate host value. Your API call URL should only contain the base endpoint without the query parameters. I faced a similar challenge when I began using RapidAPI, and it took me a while to resolve it. Additionally, if needed, make sure to include ‘content-type’ in your headers as well.
