Problem with data formatting in Voiceflow API block POST request
Hi,
I am encountering a problem when performing POST request from voiceflow API block to my server. When I enter the data in json format in the 'Raw' section of body it works, but when I enter it in the 'Form Data', it gives a content type error.
I need to use the form data format because it allows me to send voiceflow variable to my server.
Could anyone please help me with that?

To resolve the issue you're encountering with the Voiceflow API block when performing a POST request, follow these steps:
1. Use JSON Format in 'Raw' Section:
- Ensure that your data is correctly formatted as JSON when using the 'Raw' section. This is the preferred method for sending structured data.
2. Form Data Format:
- If you need to use the 'Form Data' format to send Voiceflow variables, make sure that the content type is set correctly. The 'Form Data' format typically requires

By following these steps, you should be able to successfully send data using the 'Form Data' format in Voiceflow's API block without encountering content type errors.You can send vars in the raw body too. Just enter it like:
