## An error occurred when calling Get All

### Unsupported content type: application/vnd.api+json

I am stuck. I keep getting this error

An error occurred when calling Get All  
Unsupported content type: application/vnd.api+json

And I don’t know how to convert it to simple “application/json” if that’s ever a solution.

Could someone please help?

Hi Chris,

Welcome to the Community! 🥳

The content type is ONLY supposed to be:

application/json

Thanks for the reply.

The api I have has application/vnd.api+json in the header. I’m unable to change this.

Is there a workaround?

Can you take a screenshot of your API request setup?

Remember to blur any confidential information. (API key, account #, etc…)
