Hi @rawagmbh,
Welcome to the forum!
I don’t think you can upload images directly to an external collection in Airtable.
You could try the workaround (I assume you have an image picker and upload button)
- create external collection (Airtable)
- add temporary Image property to user
- on “upload” button, add an action to update logged-in user with the image from image picker
- create a custom action to create new record in airtable (POST), and construct the JSON in a way, that it gets image URL from logged-in user temp image’s URL.
- with this, airtable will “copy” the image to the collection.
I tried this approach, worked for me.
You can also have a look at this thread: Downloading images from an Adalo collection - #7 by rregueira
Using Integromat might be a possible solution as well.
Best regards, Victor.
