How Can I Fix A Transaction Error In Ios Iap?

Hello! so i've been having this problem on my app, android IAP is working fine but on iOS I keep getting this transaction error there is nothing wrong with the product Id I put it, I can't seem to find the problem help please?

 

Have you created a Sandbox User in iTunes Connect?
Are you logged in with the Sandbox User Apple ID on your device?

 

nope, but I am going to try

 

It won’t connect unless you use a Sandbox user.

 

how do I use my sandbox tester? I am new to publishing to IOS lol.

 

You have to log into iTunes Connect, Go to Users, Create Sandbox User.
Confirm the Apple ID, then log in on your phone using that ID, then try your purchase.

 

okay ty

 

AaroArts, it says iTunes account creation not allowed?

 

Do you have an Apple License?
You should be able to Log In to your iTunes Connect Account and go to the Users and Roles section to create one.
Use an email that doesn’t have an Apple ID yet.

 

yep. I just need to log on my sandbox tester account on iTunes & App Store right?

 

Ok, once you’ve logged into iTunes Connect online, and created a Sandbox User, you might have to verify the account via email.
Then you log out of your Apple ID on your device and log in using your Sandbox User.
Then go to your App and test the IAP.

 

yep, I did create one verified it too. and whenever I try to log it in it says "iTunes account creation not allowed."

 

Uh, I just logged it in and tested my app and it still says Transaction Error what did I do wrong.

 

Have you added your IAP in the App Build section of your App in iTunes Connect? (So the purchase is live).

 

yes, I did.

 

Well, if you've done the following:

• Signed all Apple Dev Documents and have a License,
  
• IAP IDs match in BuildBox/iTunes Connect,
• Added IAPs to App so they're live,
• Created a SANDBOX User in "Users and Roles",
• Confirmed your new User via email,
• Logged into your Sandbox Apple ID on your Device,
• Booted the latest BB Build,

I don't see why it isn't working.
It should work on the simulator AND real devices.

 

I think I just found the problem, thanks a ton for helping!

 

ugh, it still doesn't work I double checked every single thing and still won't work!

 

This error usually appears if you dont add your in-app purchases to the app settings on itunes connect for transmitting your build for review.

 

I did.I really don't know on what is wrong I double checked everything. I don't know what's the problem been trying to figure this out for weeks. help please! this is really frustrating.
