Hello there,
I'm currently working on a client portal and I need to be completely free from Portal restrictions such as the ability to display one Entity Form from CRM on a page, but only one at a time.
I used Liquid Templating a lot in order to request data from the CRM thanks to FetchXML tags and display them as I want, with my own css and JavaScript files.
The ability to read from the CRM was really important for me, but now I need to create or update records into the CRM, but I cannot afford to use native Entity Form.
With Liquid, it is possible to call forms with the Entityform tags and calling them with their name (thing I found disturbing here : https://community.dynamics.com/crm/f/117/t/244243).
Is there a way to create my own form thanks to HTML/CSS/JS and then, on button click, access the CRM to write data where I want ? I tried to use REST, web API, OData, OAuth but everything failed, and I'm stunned about the fact you can't check native Portal source file with Online CRM...
Thanks for your very kind help,
Arthur
