iOS: Create Sticker Pack via Shortcut

[OliverRM]

I wondered, is it possible to create a sticker pack from within a scripted shortcut using the iOS integrated shortcuts app?

Feel free to have a look at the shortcut I wrote: https://www.icloud.com/shortcuts/001c7f01c5db4aa59ee308383376835a

After WhatsApp opens, I receive the message “The operation couldn’t be completed. (com.third-party-stickers error 1000.)”. Is it generally not possible, to create sticker packs from within a shortcut or is there something wrong with my code?

There are 4 things wrong with your attempt. 1. The data type for paste bin content is not being set. 2. The json you are building is wrong. 3. Not enough stickers. 4 and you shouldn’t encode into a dictionary and then decode it again. That step is useless. Just use the json as input for pastebin. Kudos for the creative approach!

Thanks for your reply :)

1. How can I set it? Or is it not possible to set it from within a shortcut?
2. Oh, right. Thanks. I sent the entire root of sticker_packs.wasticker only replacing tray_image_file with tray_image and image_file with image_data. It should be a single sticker pack as in StickerPack.swift.sendToWhatsApp(completionHandler), right?
3. Thanks for pointing that out. I will try with more. Anyone who knows what the minimum (and maximum) is?
4. I am encoding the image data, not the dictionary.

Using Shortcut app works. We have done that in the past.

Prove it!

j/k, I'll try to replicate it in a bit and post results
