Trello API and Custom Fields

We are integrating Trello with our application. When we try to update a Card with some custom fields (like Priority, Status, Attachment, LoggedDate etc.), we have to send a request for each fields separately. Can't we create a request which accepts all the custom fields and make a call to Trello API ?

For Ex: Currently I am making a Trello API call for each fields separately as shown below. However I can't make a single request to Trello with all custom fields in one shot. Please advise.

Request for Priority:




  "key": "<key>",

  "token": "<token>"


Request for Loggedby:


  "value": {"text": "<name>"},

"key": "<key>",

 "token": "<token>"

Hey Elango,

You're correct; there isn't currently a way to update multiple custom field values on a single card. Each value for each custom field must be updated by an individual call.

I'll pass along the request to add support for updating multiple custom field values on a single card with a single call, though.

Hey there Bently 👋  wondering if this ever was addressed? Having a hard time finding documentation that would suggest it was. Look forward the response ;)

It was not and, unfortunately, I do not expect it to be updated.
