(PLATFORM error 580022.) - Invalid request parameter: Payer Email cannot be blank

[glaidler]

We are getting the above intermittently with one of our customers.

Can you clarify what the validation rules are for payerEmail field - is it allowing empty strings but not null (the sample on Tim Messerschmit's blog has an emptry string), and considering the whole approach of paypal here, surely an email is not required?

Hi Graham,

Can you give us the following information to help us debug the issue:

• Platform: iOS or Android?
• What version of the app is the user using?
• Do you have an example request that reproduces the error?

[lernerb]

If you look at our documentation here we note the validation rule that you are looking for:

Sending an invoice field with no value (for example, sending “payerEmail”: “”) will cause unexpected behavior, so remove any fields that lack a value.

Many thanks - sure that wasn't there before, but may well be wrong.

All I would say is update the sample on the blog - this has a blank payerEmail.

Will do, I've sent an email to Tim to update his blog.

Thanks @glaidler and @lernerb - I've updated the gist to reflect the payerEmail field changes.
