Upload image together with message

[renja-g]

Hi, right now I have an endpoint where I can upload images (following the file-upload-guide)
I also have an endpoint where I can create a message, a I have also made a relation to the image entity.
But If I now would like to send a message with an Image, I would have to make two requests.

Is there a way how I can make an endpoint that is wrapping the two endpoints together or what would you recommend?

Hello,
You need to create a resource containing both the message and the image and follow this guide: https://api-platform.com/docs/core/file-upload/#uploading-to-an-existing-resource-with-its-fields.

At the end I would have:
Message entity (json)
Image entity (multipart/form-data)
and
MessageImage entity (multipart/form-data)
right?

That's right. The MessageImage resource can also be retrieved in JSON(-LD).

But don't I need from-data to upload a file?

[alanpoulain]

Yes you need it. But you can also add JSON(-LD) (not for creation).
