Hi,

I am trying to connect to an API with a custom connector.

I have it working in postman but for some reason the Custom connector is complaining about a missing parameter when it is clearly defined in the swagger code.

swagger:

i have done other post requests before, but this one is causing me a whole lot of problems.

What is going on ?

Help please?

passing the parameter as a single body string :
{
{"username" : "API_USER"}
}

Hi @DragonLord ,
What is expected content type by your API? Power Automate passed this request with 'application/json' content-type and you can see the actual body toggling 'Raw Body' option, the error message was generated by the backend API.
Please note, if the endpoint requires 'application/x-www-form-urlencoded' content, it is not fully supported. A workaround for this would be to have a single string body parameter and its complete value generated manually.
Best regards,
Dmitry
