Hey there! Documint pack creator here
You actually don’t need to even use or create a pack to ingest a URL and store it locally in Coda.
As long as you have the hosted image url you can simply push it into an an image/file type column and Coda will automatically fetch the image, host it on their servers, thus storing it locally in a table
For example, if you catch a webhook with an image URL in a payload and pass its results to a file type or image column, Coda will do all the work for you.
That’s how documint does it. Simply returns an Amazon url into a coda file type column which converts and stores the new pdf locally.
As I said, you dot. Even need a pack. You could just use a Coda ModifyRows() button to push a string url into a file type column and Coda will fetch the file/image stored elsewhere and store it locally.
Ask away if you have any more questions!
