Get members's avatarHash when getting cards from Trello

Question

According to the Trello API documentation, it is possible to return a member's avatarHash as part of the data for the cards on a list. I should be able to use the feed from either of the following:

• https://trello.com/1/lists/[LIST_ID]/cards?member_fields=all
• https://trello.com/1/lists/[LIST_ID]/cards?member_fields=avatarHash

However, for me anyway, the data is exactly the same with or without the query paramaters. I have also tried adding my application key and a token to the URL, but still no success.

What I actually want to do is get the URI for a member's avatar, and I believe I can build the correct one with the hash. Any help to do this or any pointers as to what I am doing wrong will be greatly appreciated.

Answer 1

Trello's documentation for their API shows that there are optional fields, but it isn't clear or even stated (although fairly obvious after reading) that for the member_fields parameter to be valid, there should also be members=true specified as part of the URI.

I came across this when inspecting the API calls Trello make themselves and having removed everything but member_fields, things even went missing for them, but adding members back in worked as expected.

Right now, my API call is finally working and looks like this:

• https://trello.com/1/lists/[LIST_ID]/cards?members=true&member_fields=avatarHash
