Upload attachment with API on VBA

Damien Lohier February 29, 2024

Hello,
I try to upload a file to a Trello card with my VBA application, but I always receive status 400 from the API.

 

Here is what I see in network tab of Firefox when I upload a file:

 

-----------------------------21770600522523212291266470825
Content-Disposition: form-data; name="dsc"

c27e21f98df1b3ed8f[...]7d49d9daf562557675dc7
-----------------------------21770600522523212291266470825
Content-Disposition: form-data; name="numOfFiles"

1
-----------------------------21770600522523212291266470825
Content-Disposition: form-data; name="fileIdx"

0
-----------------------------21770600522523212291266470825
Content-Disposition: form-data; name="file"; filename="test.txt"
Content-Type: text/plain

this is a test file


-----------------------------21770600522523212291266470825-

I tried to send a POST request with a body having the same format, but I got a status 400 (Bad request).
I have just removed the "dsc" part, I don't know what is it or how I can calculate it. Is it mandatory ?


Query: https://api.trello.com/1/cards/[my card id]/attachments

Am I doing something wrong ?

Again, the API docs are not very useful in this case:

Hi @Damien Lohier! For this type of question, I recommend you post at the Atlassian Developer Community at https://community.developer.atlassian.com/c/trello/42. This is the best place for you to get answers about issues with custom scripts you've developed using Trello's API. Also, other developers (including Trello engineers) are actively interacting there, and they might be better suited to help you with that. Thanks for your understanding!
