Thanks, your suggestions has resolved the issue. But I got limitation over there, when am using custom text field, character limit is set to 255.

If I make any changes in the limit of text fields, will impact existing custom text fields too.

How do I increase the limit only to specific fields?

The API already returns data in JSON format.

If you want to store as JSON, write JSON into a text field.  If you want plain text, stored as JSON, you'll need to write a new custom field type that can take input and reformat it as JSON, and return it in a viewable format that you prefer (noting that if that is JSON, the API will return JSON within JSON)
