How do I get an application id for Paypal?

Question

In order to go live, you need to register your application with PayPal to obtain an application ID.

When you submit your application to PayPal for review, the application is quickly scanned for the requests to PayPal operations. If no "advanced" operations are found, PayPal issues an AppID for the production servers at the time you submit the application.

Just because PayPal docs are kind of messy like @Deekor said in the comments, I think it would be good to leave the following links in case anybody like me is wondering where the hell do you REALLY get an AppID (e.g.: for adaptive payments).

• Just go to PayPal Developer, once you log in, go to Create and manage Classic API apps or directly to PayPal Apps.
• Create an app, once created you get a Sandbox ID which is you AppID and the LiveID as pending.

Hi All - I will update this since it's been a while. Please note this is for the classic Adaptive Payment APP ID (NVP/SOAP APIs) process and not for the REST APP or BrainTree V.Zero SDK.

Do the following:

1. Go to developer.paypal.com
2. Log in with PayPal Account email and password
3. Click the 'Dashboard' tab up top
4. Click 'My APPs & Credentials'
5. Click 'Create & Manage NVP/SOAP API apps link
6. On the redirect to the classic developer portal, Login to PayPal account you want to apply for the APP ID with (a business PayPal account is highly suggestive for underwriting approval)
7. For Live APP IDs it takes between 24-48 hours; you should get notified when approved. If you don't, contact business support. The number is in your paypal account / contact us section (pending status)
8. For SandBox you'll get the APP ID right away, regardless of how you applied; live or sandbox
9. You should see the APP ID in the classic developer portal in the 'manage your apps' section.
