Collection background image
How to set backdrop_path in user's collection using http request? (Mobile)

If I understood your question correctly...

Background images for your lists, or user collections as you say,
can only be a background image from one of the films on your list.
It is not possible to use or upload an external image.

User collections json response of single collection (https://developer.themoviedb.org/v4/reference/account-lists)

{ "account_object_id": "___", "adult": 0, "average_rating": 7.9, "backdrop_path": "/38aCLy0BdFbOAIEfuDladoITHN0.jpg", "created_at": "2024-03-06 22:47:38 UTC", "description": "Фильмы которые я посмотрел", "featured": 0, "id": 8293167, "iso_3166_1": "UA", "iso_639_1": "uk", "name": "Просмотренные", "number_of_items": 12, "poster_path": null, "public": 1, "revenue": 3294665949, "runtime": "1477", "sort_by": 1, "updated_at": "2024-05-31 16:00:05 UTC" }

By default backdrop_path == null. Can i set some string in that field using API?

For some reason i get error when trying to send json code with code style

Again, I'm not sure I understand correctly.

The _path backdrop is in the response.
"backdrop_path": "/38aCLy0BdFbOAIEfuDladoITHN0.jpg",
To access the image use the images URL.
https://developer.themoviedb.org/docs/image-basics

The request should be similar to these:

https://image.tmdb.org/t/p/[size]/[poster_path]  
https://image.tmdb.org/t/p/original/38aCLy0BdFbOAIEfuDladoITHN0.jpg  
https://image.tmdb.org/t/p/w500/38aCLy0BdFbOAIEfuDladoITHN0.jpg  

https://image.tmdb.org/t/p/original/38aCLy0BdFbOAIEfuDladoITHN0.jpg

Make sure to read the documentation around images.

I understand how to get image from response. But can i set it? So that in the future, I can get the backdrop_path that I set by myself.

I can do it on the site (https://www.themoviedb.org/list/8293167/edit?active_nav_item=step_3), but can i do the same thing using API?

I want to edit info about one of my collection, to get in the future response that i set. There is a request for this (https://developer.themoviedb.org/v4/reference/list-update), but in the request example there is no info about putting backdrop_path

I hope i said all of this correctly, just in case, sorry for bad English. Hello from Ukraine!

Hello from Brazil. :-)
English is also not my native language.

I do not think so.
It must be an image that already exists here on TMDb.
You cannot enter a URL.

No. Only on the WEB interface. You cannot do this using the API.

I have never used the V4 version of the API.
I'm not the best person to clarify details.
You'd better open a specific topic for this.
Something like API v4 - Update - How to use it?

Hi @lLump,

You can actually pass a backdrop_path param to the update list request I believe. Did you try and it failed?
