Hello!  It might be best to first upgrade your DNN site from 9.1.1.  That version is quite old.  It's using hundreds of deleted DNN API endpoints that you may have to fix later, and you're building and using a version of DNN which has known security bulletins.  Effectively, you're starting from a place of building a lot of technical debt.  

As for My Tokens, you may be better off trying to get support from that vendor.  While some people here do/have used that in the past, this is more of a DNN forum.  Each extension vendor tends to have a place to ask for support for their various respective extensions.  

My question is not about My tokens. I just pasted what was on the Post Data field of the Server Request action. I tried to set the post data with a json body it didnt work. I tried with key value pairs as mentioned above. Nothing works. I thought that was a DNN question.

Oh, I guess I misunderstood that, but My Tokens and Action Form aren't DNN.  They're products of DNN Sharp which get installed into DNN.    

If this is a DNN question, I'm not sure what you're trying to do.  This seems like it could be a development question then.  If it is, can you provide more details about what you're doing and how you're doing it?  Is this in a module, library, theme, or in something else?  What kind of code is creating the server request and action? 🤔 

Sujatha,
No disrespect but this is a question about “action forms” which is running on DNN. So you need to direct your question to DNN sharp. Start here. https://www.dnnsharp.com/helpcenter

Oh so Action Form isnt DNN? Sorry I am totally new to this platform. I am just trying to build a form with a few fields and a button which when clicked will make an API call. The API only accepts json. The API call works perfect when I test from Postman but the same doesnt work from the action form action called Server Request. I dont know where to ask questions about Action Form or Action Grid. Do you have any suggestions? Thank you!

Thanks Saw the other reply. WIll check the sharp forum.

No problem, and welcome to the DNN community. Please feel free to come back if you still have questions that don’t get answered. Or any other DNN topics. Since you’re new to DNN, it’s sometimes difficult to know where to look. But we will do our best to get you an answer. 🙂

PS. Echoing Will’s recommendation, you should be looking to update to a newer version. We realize now that you’re new to DNN, and still trying to figure things out, but if you really are on 9.1, that’s about 8 years old 😒
Your first step is to make sure you have a good dev/test environment.

Maybe nice to know: DNN Sharp upped their game about 7 years ago. Their modules (action grid, action form, my tokens but also scheduler and a workflow engine)  were integrated in a full force low code platform. Still running on DNN and a way to be much more productive regarding development. You can check it out on https://www.plantanapp.com/ 

For DNN context not cheap. Compared to Mendix or Outsystems really affordable.
